Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	Organization and Description of Business Description of Business Remitly Global, Inc. (the “Company” or “Remitly”) was incorporated in the State of Delaware in October 2018 and is headquartered in Seattle, Washington, with various other global office locations. The Company provides integrated financial services to immigrants, including helping customers send money internationally in a quick, reliable, and more cost-effective manner by leveraging digital channels. Remitly supports cross-border transmissions across the globe. Unless otherwise expressly stated or the context otherwise requires, the terms “Remitly” and the “Company” in these notes to the condensed consolidated financial statements refer to Remitly Global, Inc. and its wholly-owned subsidiaries. Initial Public Offering and Private Placement In September 2021, the Company completed its initial public offering (the “IPO”), in which the Company issued and sold 7,000,000 shares of its common stock at $43.00 per share. Concurrently, 5,162,777 shares were sold by certain of the Company’s existing stockholders. In addition, the Company issued 581,395 shares of common stock to an existing stockholder in a private placement at the same offering price as the IPO. The Company received net proceeds of $305.2 million for the IPO and private placement, after deducting underwriting discounts and other fees of $20.8 million. In connection with the IPO, 127,410,631 shares of outstanding redeemable convertible preferred stock automatically converted into an equivalent number of shares of common stock on a one-to-one basis.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP and therefore the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the historical audited annual consolidated financial statements and related notes included in the Company’s final prospectus dated September 22, 2021 and filed with the SEC pursuant to Rule 424(b)(4) (the “Final Prospectus”). The accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company's consolidated financial position, results of operations, comprehensive loss, and cash flows for the interim periods. The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or for any other future annual or interim period. Principles of Consolidation The condensed consolidated financial statements include the accounts of Remitly Global, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. These estimates and assumptions include, but are not limited to, revenue recognition including the treatment of sales incentive programs, reserves for transaction losses, stock-based compensation expense including the estimated fair value per share of common stock, the carrying value of operating lease right-of-use assets, the recoverability of deferred tax assets, and capitalization of software development costs. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Actual results could differ from these estimates and assumptions, and these differences could be material to the condensed consolidated financial statements. Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, disbursement prefunding, restricted cash, and customer funds receivable. The Company maintains cash and cash equivalents and restricted cash balances that may exceed the insured limits by the Federal Deposit Insurance Corporation. In addition, the Company funds its international operations using accounts with institutions in the major countries where its subsidiaries operate. The Company also prefunds amounts which are held by its disbursement partners, which typically include India, Philippines and Mexico. The Company has not experienced any significant losses on its deposits of cash and cash equivalents, disbursement prefunding, restricted cash or customer funds receivable in the nine months ended September 30, 2021 and 2020. For the three and nine months ended September 30, 2021 and 2020, no individual customer represented 10% or more of the Company’s total revenues. As of September 30, 2021 and December 31, 2020, no individual customer represented 10% or more of the Company’s customer funds receivable. Advertising Advertising expenses are charged to operations as incurred and are included as a component of marketing expenses. Advertising expenses totaled $25.6 million and $15.9 million during the three months ended September 30, 2021 and 2020, respectively, and are used primarily to attract new customers. Advertising expenses totaled $70.1 million and $42.5 million during the nine months ended September 30, 2021 and 2020, respectively. Summary of Significant Accounting Policies The Company’s significant accounting policies are discussed in Note 2, “Basis of Presentation and Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements as of December 31, 2020 and 2019 and for the years ended December 31, 2020 and 2019 included in the Final Prospectus. There have been no significant changes to these policies during the nine months ended September 30, 2021, except as noted below. Deferred Offering Costs Prior to the IPO, deferred offering costs, which consist of direct incremental legal, accounting, and consulting fees relating to the IPO, were capitalized and included in other non-current assets on the condensed consolidated balance sheets. Upon completion of the IPO in September 2021, the Company reclassified $4.3 million of deferred offering costs to additional-paid-in capital offsetting the IPO proceeds. As of September 30, 2021, approximately $1.9 million of IPO costs were unpaid.

Recent Accounting Pronouncements Accounting Pronouncements Not Yet Adopted In 2021, The Financial Accounting Standards Board (“FASB”) issued ASU 2021-04, Earnings per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The FASB is issuing this update to clarify and reduce diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The amendments affect entities when a freestanding equity-classified written call option (such as a warrant) is modified or exchanged and remains equity classified after the modification or exchange. In addition, the amendments impact the recognition and measurement of earnings per share for certain modification and exchange transactions. The new standard is effective for the Company for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently assessing the impact of the guidance on its consolidated financial statements. There are other new accounting pronouncements issued by the FASB that we have adopted or will adopt, as applicable. We do not believe any of these accounting pronouncements have had, or will have, a material impact on our condensed consolidated financial statements or disclosures.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue The Company’s revenue is generated on transaction fees charged to customers and foreign exchange spreads between the foreign exchange rate offered to customers and the foreign exchange rate on the Company's currency purchases. Revenue is recognized when control of these services is transferred to the Company’s customers, which is the time the funds have been delivered to the intended recipient in an amount that reflects the consideration the Company expects to be entitled to in exchange for services provided. The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) Revenue from Contracts with Customers (Topic 606), which includes the following steps: (1) identification of the contract with a customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, the Company satisfies a performance obligation. Revenue is derived from each transaction and varies based on the funding method chosen by the customer, the size of the transaction, the currency to be ultimately disbursed, the rate at which the currency was purchased, and the countries to which the funds are transferred. The Company’s contract with customers can be terminated by the customer without a termination penalty up until the time the funds have been delivered to the intended recipient. Therefore, the Company’s contracts are defined at the transaction level and do not extend beyond the service already provided. The Company’s service comprises a single performance obligation to complete transactions for the Company’s customers. Using compliance and risk assessment tools, the Company performs a transaction risk assessment on individual transactions to determine whether a transaction should be accepted. When the Company accepts a transaction and processes the designated payment method of the customer, the Company becomes obligated to its customer to complete the payment transaction. The Company recognizes transaction revenue on a gross basis as it is the principal for fulfilling payment transactions. As the principal to the transaction, the Company controls the service of completing payments on its payment platform. The Company bears primary responsibility for the fulfillment of the payment service, is the merchant of record, contracts directly with its customers, controls the product specifications, and defines the value proposition of its services. The Company is also responsible for providing customer support. Further, the Company has full discretion over determining the fee charged to its customers, which is independent of the cost it incurs in instances where it may utilize payment processors or other financial institutions to perform services on its behalf. These fees paid to payment processors and other financial institutions are recognized as transaction expenses in the consolidated statements of operations. The Company does not have any deferred contract acquisition costs. Deferred Revenue The deferred revenue balances from contracts with customers were as follows: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Deferred revenue, beginning of the period $ 1,126 $ 274 $ 1,105 $ 137 Deferred revenue, end of the period 1,269 1,010 1,269 1,010 Change in deferred revenue during the period 143 736 164 873 Revenue recognized during the three month periods ended September 30, 2021 and 2020 from amounts included in deferred revenue at the beginning of the period were $0.3 million and $0.2 million, respectively. Revenue recognized during the nine month periods ended September 30, 2021 and 2020 from amounts included in deferred revenue at the beginning of the period were $0.3 million and $0.1 million , respectively. Deferred revenue represents amounts received from customers for which the performance obligations are not yet fulfilled. Deferred revenue is included within accrued expenses and other current liabilities and other non-current liabilities on the consolidated balance sheets. Sales Incentives The Company provides sales incentives to customers in a variety of forms. Cash incentives given to customers are accounted for as reductions to revenue, up to the point where net historical cumulative revenue, at the customer level, is reduced to zero. Those additional incentive costs that would have caused the customer level revenue to be negative are classified as advertising expenses and are included as a component of marketing expenses. In addition, referral credits given to a referrer are classified as marketing expenses. During the three months ended September 30, 2021 and 2020, payments made to customers resulted in reductions to revenue of $4.3 million and $3.7 million, respectively, and charges to sales and marketing expense of $2.6 million and $2.4 million, respectively. During the nine months ended September 30, 2021 and 2020, payments made to customers resulted in reductions to revenue of $13.4 million and $12.2 million, respectively, and charges to sales and marketing expense of $8.4 million and $7.6 million, respectively.

Debt Disclosure [Abstract]
Debt	Debt Secured Revolving Credit Facility New Revolving Credit Facility On September 13, 2021, Remitly Global, Inc. and Remitly, Inc. (U.S. subsidiary) entered into a new credit agreement (the “New Revolving Credit Facility”), as co-borrowers, with certain lenders and JPMorgan Chase Bank, N.A. acting as administrative agent and collateral agent, that provides for revolving commitments of $250.0 million and terminated its existing Revolving Credit Facility. Proceeds under the New Revolving Credit Facility are available for working capital and general corporate purposes. As part of the refinancing, the Company performed a debt modification analysis, utilizing the borrowing capacity test within ASC 470-50, Debt — Modification and Extinguishment , on a lender-by-lender basis, resulting in the capitalization of $1.4 million of new debt issuance costs incurred in connection with the New Revolving Credit Facility, of which $0.4 million remained accrued and unpaid as of September 30, 2021. Such amounts were capitalized and recorded within other long-term assets, net in the condensed consolidated balance sheet, and will be amortized to interest expense over the term of the New Revolving Credit Facility. The Company previously had $0.5 million of unamortized debt issuance costs associated with its existing Revolving Credit Facility. As a result of the debt modification analysis, the Company will continue to amortize $0.4 million of unamortized debt issuance costs over the term of the New Revolving Credit Facility. The remaining $0.1 million was expensed as a debt extinguishment cost within interest expense in the condensed consolidated statement of operations for the three and nine months ended September 30, 2021. The New Revolving Credit Facility was used to refinance its existing Credit Agreement. The New Revolving Credit Facility provides for access to $250.0 million in revolving borrowings and has a maturity date of September 2026. Borrowings under the New Revolving Credit Facility accrue interest at a floating rate per annum equal to, at the Company’s option, (1) the Alternate Base Rate (defined in the New Revolving Credit Facility as the rate per annum equal to the highest of (a) the Prime Rate in effect on such day, (b) the NYFRB Rate in effect for such day plus 0.50% and (c) the Adjusted LIBO Rate plus 1.00%, subject to a floor of 1.00% plus 0.50% or (2) the Adjusted LIBO Rate (subject to a floor of 0.00%) plus 1.50%. In addition, there is an unused commitment fee, which accrues at a rate per annum equal to 0.25% of the unused portion of the revolving commitments, and is payable quarterly. The New Revolving Credit Facility contains customary conditions to borrowing, events of default and covenants, including covenants that restrict the ability to dispose of assets, merge with other entities, incur indebtedness, grant liens, pay dividends or make other distributions to holders of its capital stock, make investments, enter into restrictive agreements or engage in transactions with affiliates. As of September 30, 2021, financial covenants in the New Revolving Credit Facility include (1) a requirement to maintain a minimum Adjusted Quick Ratio of 1.50:1.00, which is tested quarterly and (2) a requirement to maintain a minimum Liquidity of $100.0 million, which is tested quarterly. The obligations under the New Revolving Credit Facility are guaranteed by the Company’s material domestic subsidiaries, subject to customary exceptions, and are secured by substantially all of the assets of the borrowers and guarantors thereunder, subject to customary exceptions. Amounts of borrowings under the New Revolving Credit Facility may fluctuate depending upon transaction volumes and seasonality. The Company was in compliance with all financial covenants as of September 30, 2021. The Company had no outstanding borrowings under the New Revolving Credit Facility as of September 30, 2021. The Company had unused borrowing capacity of $250.0 million under the New Revolving Credit Facility as of September 30, 2021. In addition, the New Revolving Credit Facility includes a letter of credit sub-facility. As of September 30, 2021, the Company had $19.2 million in standby letters of credit outstanding. 2020 Credit Agreement In November 2020, the Company modified its existing credit agreement (the “Credit Agreement”). As a result, the Credit Agreement provided the Company with access up to $150.0 million in revolving credit facility borrowings with the maturity date of November 16, 2023. Revolving credit facility borrowings are subject to mandatory repayment within 20 business days in an amount necessary to reduce the borrowings, in the aggregate, to an amount less than the Company’s customer funds account maintained with the lender. Interest on borrowings under the revolving credit facility accrues at a floating rate per annum equal to (i) ABR defined in the Credit Agreement as the rate per annum equal to the highest of (a) the Prime Rate in effect on such day, (b) 3.25% and (c) the Federal Funds Effective Rate in effect for such day plus 0.50% plus (ii) 1.0%. In addition, an unused revolving line facility fee accrues at a floating rate equal to 0.40% of the unused portion of the line, payable monthly. As of December 31, 2020, the interest rate of the borrowings under the revolving credit facility was 4.25%. As of December 31, 2020, the Company had outstanding borrowings under the revolving credit facility of $80.0 million and an unused borrowing capacity of $70.0 million.

Earnings Per Share [Abstract]
Net Loss Per Common Share	Net Loss Per Common Share Basic and diluted net loss per share attributable to common stockholders is computed using the two-class method required for participating securities. Prior to the automatic conversion of all of its redeemable convertible preferred stock outstanding into common stock upon the completion of the IPO, the Company considered all series of the Company’s redeemable convertible preferred stock and early exercised stock options to be participating securities, as the holders of such stock have the right to receive dividends on a pari passu basis in the event that a dividend is declared on the common stock. Upon completion of the IPO, all of the Company’s redeemable convertible preferred stock was converted to common stock. After the IPO, the Company’s early exercised stock options continue to be participating in nature. Under the two-class method, basic net loss per share is computed by dividing net loss adjusted to include deemed dividends on redeemable convertible preferred stock by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income attributable to common shares by the weighted-average number of common shares determined for the basic earnings per share plus the dilutive effect of stock options, restricted stock units (“RSUs”), common stock warrants and redeemable convertible preferred stock. As the Company reported a net loss, diluted net loss per share was the same as basic net loss per share because the effects of potentially dilutive items were anti-dilutive for all periods presented. The following table presents the calculation of basic and diluted net loss per share attributable to common stockholders for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, (in thousands, except share and per share amounts) 2021 2020 2021 2020 Numerator: Net loss $ (12,962) $ (2,429) $ (22,180) $ (23,559) Deemed dividend — — — — Net loss attributable to common stockholders $ (12,962) $ (2,429) $ (22,180) $ (23,559) Denominator: Weighted-average shares used in computing net loss per share attributable to common stockholders: Basic and diluted 31,641,400 21,868,865 26,055,903 21,186,012 Net loss per share attributable to common stockholders: Basic and diluted $ (0.41) $ (0.11) $ (0.85) $ (1.11) The following potentially dilutive securities were excluded from the computation of diluted net loss per share calculations for the periods presented because the impact of including them would have been anti-dilutive: As of September 30, 2021 2020 Redeemable convertible preferred stock — 127,082,605 Common stock warrants — 256,250 Stock options outstanding 24,061,073 19,934,198 RSUs outstanding (1) 1,301,084 — Shares subject to repurchase 554,973 1,875,822 Total 25,917,130 149,148,875 (1) A portion of these RSUs were subject to a performance-based vesting condition until September 22, 2021.

Stock-Based Compensation	Stock-Based Compensation In 2011, the Company adopted the Equity Incentive Plan (the “2011 Plan”), as amended, which provided for the issuance of up to 43,899,677 incentive stock options, nonqualified stock options, restricted common stock, and RSUs and stock appreciation rights to employees, directors, officers, and consultants of the Company. In September 2021, the Company adopted the 2021 Equity Incentive Plan (the “2021 Plan”, and together with the 2011 Plan, the “Plan”) as a successor to the 2011 Plan. The 2021 Plan authorizes the award of both incentive stock options, nonqualified stock options, restricted common stock, stock appreciation rights, restricted stock units, and performance and stock bonus awards. Pursuant to the 2021 Plan, incentive stock options may be granted only to Company employees. The Company may grant all other types of awards to its employees, directors, and consultants. The 2021 Plan is administered by the Company’s board of directors, which determines the terms of the options granted, including exercise price, number of options granted, and vesting period of such options. The 2021 Plan provides for the issuance of up to 25,000,000 shares of common stock, plus any reserved shares not issued or subject to outstanding grants under the 2011 Plan, which was 552,736 on the effective date of the 2021 Plan, for a total of 25,552,736 shares reserved for issuance under the 2021 Plan. The number of shares reserved for issuance under the 2021 Plan will increase automatically on January 1 of each of 2022 through 2031 by the number of shares equal to 5% of the aggregate number of outstanding shares of all classes of common stock as of the immediately preceding December 31, or a lesser number as may be determined by the Company’s talent and compensation committee, or by the Company’s board of directors acting in place of the talent and compensation committee. In addition, in September 2021, the Company adopted the 2021 Employee Stock Purchase Plan (the “ESPP”) to enable eligible employees to purchase shares of common stock with accumulated payroll deductions. The ESPP provides for the issuance of up to 3,500,000 shares of common stock. The number of shares reserved for issuance and sale under the ESPP will increase automatically on January 1 of each of 2022 through 2031 by the number of shares equal to 1% of the aggregate number of outstanding shares of all classes of common stock as of the immediately preceding December 31, or a lesser number as may be determined by the Company’s talent and compensation committee, or by the Company’s board of directors acting in place of the talent and compensation committee. Subject to stock splits, recapitalizations, or similar events, no more than 35,000,000 shares of common stock may be issued over the term of the ESPP. The ESPP is intended to qualify under Section 423 of the Code, provided that the administrator may adopt sub-plans under the ESPP designed to be outside of the scope of Section 423 for participants who are non-U.S. residents. As of September 30, 2021, no awards have been granted under the ESPP, as the grant date criteria pursuant to ASC 718, Stock-Based Compensation, has not yet been met. The grant date for awards under the ESPP was met in October 2021, upon mutual agreement of terms and conditions, and the Company expects to recognize compensation expense related to the ESPP beginning with the fourth quarter of 2021. As of September 30, 2021 and December 31, 2020, 25,594,331 and 206,529 options remain available for issuance under the 2021 Plan and 2011 Plan, respectively. During the period ended September 30, 2021 and December 31, 2020, activity and amounts related to awards to nonemployees under the Plan were not material. Stock Options Stock options granted under the Plan generally vest over a period from two years to four years from the vesting commencement date on a monthly basis with or without a one-year cliff or, for non-employees, ratably on a monthly basis over a shorter period, depending upon anticipated duration of services. Other vesting terms are determined by the Company’s board of directors. All options granted under the Plan are exercisable for up to ten years from the grant date, subject to vesting. In the event of termination of service, option will generally remain exercisable, to the extent vested, for three months following the termination of service. The following is a summary of the Company’s stock option activity during the nine months ended September 30, 2021: Stock Options (in thousands, except share and per share amounts) Number of Options Outstanding Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life (Years) Aggregate Intrinsic Value (1) Balances as of January 1, 2021 21,034,424 $ 1.88 7.82 $ 64,604 Granted 8,219,753 7.26 Exercised (4,021,834) 1.84 66,970 Forfeited (1,171,270) 3.24 Balances as of September 30, 2021 24,061,073 3.68 7.91 785,826 Vested and exercisable as of September 30, 2021 9,397,761 1.63 6.47 320,288 Vested and expected to vest as of September 30, 2021 24,561,046 $ 3.66 7.91 $ 802,853 _________________ (1) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock options and the estimated fair value of the Company’s common stock. The fair value of each employee stock option granted during the three and nine months ended September 30, 2021 and 2020 was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions: Three Months Ended September 30, Nine Months Ended September 30, 2021 2020 2021 2020 Risk-free interest rates 0.74% to 1.1% 0.30% to 0.40% 0.32% to 1.19% 0.30% to 1.47% Expected term (in years) 5.0 to 6.5 years 5.1 to 6.1 years 3.5 to 6.8 years 5.0 to 6.1 years Volatility 49.3% to 50.5 % 37.5% to 37.9 % 37.8% to 50.5 % 37.3% to 54.0 % Dividend rate — % — % — % — % Fair value of underlying common stock Prior to the completion of the IPO, the Company’s board of directors considered numerous objective and subjective factors to determine the fair value of the Company’s common stock at each meeting in which awards were approved. The factors considered included, but were not limited to: (i) the results of contemporaneous independent third-party valuations of the Company’s common stock; (ii) the prices, rights, preferences, and privileges of the Company’s redeemable convertible preferred stock relative to those of its common stock; (iii) the lack of marketability of the Company’s common stock; (iv) actual operating and financial results; (v) current business conditions and projections; (vi) the likelihood of achieving a liquidity event, such as an initial public offering or sale of the Company, given prevailing market conditions; and (vii) precedent transactions involving the Company’s shares. After the completion of the IPO, the fair value of the Company’s common stock is determined by the closing price, on the date of grant, of its common stock, which is traded on the NASDAQ. The weighted-average grant date fair value of options granted during the three months ended September 30, 2021 and 2020, was $15.31 and $1.28, respectively, and during the nine months ended September 30, 2021 and 2020 was $5.22 and $1.00, respectively. The aggregate grant-date fair value of options vested for the three months ended September 30, 2021 and 2020 was $2.1 million and $1.4 million, respectively, and for the nine months ended September 30, 2021 and 2020 was $5.4 million and $3.8 million, respectively. Stock-Based Compensation Expense Stock-based compensation expense, included in the condensed consolidated statements of operations, net of amounts capitalized to internal-use software, as described in Note 4, was as follows: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Customer support and operations $ 40 $ 5 $ 77 $ 14 Marketing 486 216 1,207 627 Technology and development 1,698 533 3,522 1,548 General and administrative 2,516 575 4,159 1,663 Total $ 4,740 $ 1,329 $ 8,965 $ 3,852 Restricted Stock Units Prior to the IPO, the Company granted performance-based RSUs (“PRSUs”) to employees and directors that continued both service-based and performance-based vesting conditions. The service-based vesting condition for these awards is typically satisfied over four years with a cliff vesting period of one year and continued vesting quarterly thereafter. The performance-based vesting condition is satisfied on the earlier of (i) the effective date of a registration statement of the Company filed under the Securities Act for the sale of the Company’s common stock or (ii) immediately prior to the closing of a change in control of the Company. Both events were not deemed probable until consummated, and therefore, stock-based compensation expense related to these PRSUs remained unrecognized prior to the effectiveness of the IPO. Upon the effectiveness of the IPO, the performance-based vesting condition was satisfied, and therefore, the Company recognized cumulative stock-based compensation expense of $1.1 million, using the accelerated attribution method for the portion of the awards for which the service-based vesting condition has been fully or partially satisfied. The remaining grant-date fair value of these PRSUs will be recognized over the remaining requisite service period. Beginning in August 2021, the Company began granting RSUs to employees and directors with service-based vesting conditions. The service-based vesting condition for these awards is typically satisfied over four years with a cliff vesting period of one year and continued vesting quarterly thereafter. The grant-date fair value of these RSUs will be recognized over the requisite service period. Restricted stock unit activity, including PRSUs, during the nine months ended September 30, 2021 is as follows: Number of Shares Weighted-Average Grant-Date Fair Value Per Share Unvested at January 1, 2021 437,369 $ 3.54 Granted 863,715 23.16 Vested (23,235) 3.54 Cancelled/forfeited — — Unvested at September 30, 2021 1,277,849 $ 16.80 No RSUs were granted during the three or nine months ended September 30, 2020.

Related Party Arrangements

Related Party Transactions [Abstract]
Related Party Arrangements	Related Party ArrangementsThe Company had promissory note agreements with two executive employees in conjunction with their early exercise of stock options to purchase 1,800,000 shares of the Company’s common stock. The principal amount of the notes was $3.1 million, and interest accrued at 2.83% on the outstanding principal amount annually. The notes were secured by the shares that were exercised. Based on the non-recourse nature of these agreements, the agreements were accounted for as grants of options to purchase common stock. The fair value of the stock options, determined using the Black-Scholes option pricing model was being recognized over the requisite service period.The associated shares are legally outstanding and included in shares of common stock outstanding in the consolidated financial statements, but were historically excluded from the Company’s net loss per common share calculations, as these shares of common stock were considered unvested until the underlying promissory notes were repaid. On August 23, 2021, the promissory notes were paid in full, including all accrued interest. After repayment of the loan, these shares are now considered outstanding for purposes of the Company’s net loss per common share calculations to the extent the shares are vested.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company computes its tax provision for interim periods by applying the estimated annual effective tax rate to year-to-date income from recurring operations and adjusting for discrete items arising in that quarter. The Company’s effective tax rates on pre-tax income wer e (2.1)% and (8.7)% for the three months ended September 30, 2021 and 2020, respectively and (5.1)% and (2.8)% for the nine months ended September 30, 2021 and 2020, respectively. The difference between the effective tax rate and the U.S. federal statutory rate of 21% in both periods was primarily the result of foreign income taxed at different rates and changes in the U.S. valuation allowance. The Company maintains a full valuation allowance against the U.S. net deferred tax assets, as it believes that these deferred tax assets do not meet the more likely than not threshold. The Company files income tax returns in the U.S. federal jurisdiction, various state jurisdictions, and internationally. As of September 30, 2021, tax years 2011 through 2020 remain open for examination by taxing authorities. The Company has applied ASC 740, Income Taxes, and has determined that it has no uncertain tax positions during the three and nine months ended September 30, 2021 and 2020, respectively. The Company recognizes interest and, if applicable, penalties for any uncertain tax positions. Interest and penalties are recorded as a component of income tax expense. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted by the United States on March 27, 2020. The CARES Act did not have a material impact on the Company’s provision for income taxes for the three and nine months ended September 30, 2021 or 2020.

Retirement Benefits [Abstract]
401(k) Defined Contribution Plan	401(k) Defined Contribution Plan The Company has a defined contribution savings plan under Section 401(k) of the Internal Revenue Code. This plan covers substantially all domestic employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. The Company makes discretionary matching contributions that are funded in the following year. The Company matches 50% of the first 3% of compensation that a participant contributes to the 401(k) plan, up to a maximum of $1,000 per plan year. The Company contributed $0.2 million to the 401(k) plan for each of the nine months ended September 30, 2021 and 2020, respectively, which represents the current period contribution for the prior plan year. No contributions were made to the plan in the three months ended September 30, 2021 and 2020. The Company may also make discretionary profit-sharing contributions. No profit-sharing contributions were made during the three and nine months ended September 30, 2021 and 2020.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Guarantees and Indemnification In the ordinary course of business to facilitate sales of its services, the Company has entered into agreements with, among others, suppliers, and partners that include guarantees or indemnity provisions. The Company also enters into indemnification agreements with its officers and directors, and the Company’s certificate of incorporation and bylaws include similar indemnification obligations to its officers and directors. To date, there have been no claims under any indemnification provisions, therefore no such amounts have been accrued as of September 30, 2021 and December 31, 2020. Litigation From time to time, the Company may be a party to litigation and subject to claims incident to the ordinary course of business, including intellectual property claims, labor and employment claims, threatened claims, breach of contract claims, and other matters. The Company accrues estimates for resolution of legal and other contingencies when losses are probable and estimable. Although the results of litigation and claims are inherently unpredictable, the Company believes that there was not at least a reasonable possibility that it had incurred a material loss with respect to such loss contingencies, as of September 30, 2021 and December 31, 2020. Reserve for Transaction Losses The Company is exposed to transaction losses including chargebacks, unauthorized credit card use, and fraud associated with customer transactions. The Company establishes reserves for such losses based on historical trends and any specific risks identified in processing customer transactions. This reserve is included in accrued expenses and other current liabilities on the condensed consolidated balance sheets. The provision for transaction losses is included as a component of transaction expenses on the consolidated statements of operations and comprehensive loss. The table below summarizes the Company’s reserve for transaction losses for the three and nine months ended September 30, 2021 and 2020: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Beginning balance $ 2,321 $ 1,761 $ 3,250 $ 798 Provisions for transaction losses 5,492 2,652 20,065 11,277 Losses incurred, net of recoveries (6,306) (2,821) (21,808) (10,483) Ending balance $ 1,507 $ 1,592 $ 1,507 $ 1,592

Segment and Geographical Information	Segment and Geographical Information The Company determines operating segments based on how its chief operating decision maker (“CODM”) manages the business, makes operating decisions around the allocation of resources, and evaluates operating performance. The Company’s CODM is its Chief Executive Officer, who reviews the Company’s operating results on a consolidated basis. The Company operates as one segment. Based on the information provided to and reviewed by the Company’s CODM, the Company believes that the nature, amount, timing, and uncertainty of its revenue and how it is affected by economic factors are most appropriately depicted through the Company’s primary geographical locations. Revenues recorded by the Company are substantially all from the Company’s single performance obligation which are earned from similar services for which the nature of associated fees and the related revenue recognition models are substantially the same. The following table presents the Company’s revenue disaggregated by primary geographical location: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 United States $ 88,852 $ 53,486 $ 238,695 $ 139,310 Canada 15,025 9,004 39,980 19,595 Rest of world 17,367 9,300 44,675 18,034 Total revenue $ 121,244 $ 71,790 $ 323,350 $ 176,939 Revenue is attributed to the country in which the customer is located.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP and therefore the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the historical audited annual consolidated financial statements and related notes included in the Company’s final prospectus dated September 22, 2021 and filed with the SEC pursuant to Rule 424(b)(4) (the “Final Prospectus”). The accompanying unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to state fairly the Company's consolidated financial position, results of operations, comprehensive loss, and cash flows for the interim periods. The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or for any other future annual or interim period.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Remitly Global, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. These estimates and assumptions include, but are not limited to, revenue recognition including the treatment of sales incentive programs, reserves for transaction losses, stock-based
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, disbursement prefunding, restricted cash, and customer funds receivable. The Company maintains cash and cash equivalents and restricted cash balances that may exceed the insured limits by the Federal Deposit Insurance Corporation. In addition, the Company funds its international operations using accounts with institutions in the major countries where its subsidiaries operate. The Company also prefunds amounts which are held by its disbursement partners, which typically include India, Philippines and Mexico. The Company has not experienced any significant losses on its deposits of cash and cash equivalents, disbursement prefunding, restricted cash or customer funds receivable in the nine months ended September 30, 2021 and 2020.
Advertising	AdvertisingAdvertising expenses are charged to operations as incurred and are included as a component of marketing expenses.
Deferred Offering Costs	Deferred Offering CostsPrior to the IPO, deferred offering costs, which consist of direct incremental legal, accounting, and consulting fees relating to the IPO, were capitalized and included in other non-current assets on the condensed consolidated balance sheets. Upon completion of the IPO in September 2021, the Company reclassified $4.3 million of deferred offering costs to additional-paid-in capital offsetting the IPO proceeds. As of September 30, 2021, approximately $1.9 million of IPO costs were unpaid. Such amounts are recorded within accounts payable and accrued expenses and current liabilities in the Company’s condensed consolidated balance sheet.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Not Yet Adopted In 2021, The Financial Accounting Standards Board (“FASB”) issued ASU 2021-04, Earnings per Share (Topic 260), Debt — Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options. The FASB is issuing this update to clarify and reduce diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options (for example, warrants) that remain equity classified after modification or exchange. The amendments affect entities when a freestanding equity-classified written call option (such as a warrant) is modified or exchanged and remains equity classified after the modification or exchange. In addition, the amendments impact the recognition and measurement of earnings per share for certain modification and exchange transactions. The new standard is effective for the Company for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently assessing the impact of the guidance on its consolidated financial statements. There are other new accounting pronouncements issued by the FASB that we have adopted or will adopt, as applicable. We do not believe any of these accounting pronouncements have had, or will have, a material impact on our condensed consolidated financial statements or disclosures.
Revenue	Revenue The Company’s revenue is generated on transaction fees charged to customers and foreign exchange spreads between the foreign exchange rate offered to customers and the foreign exchange rate on the Company's currency purchases. Revenue is recognized when control of these services is transferred to the Company’s customers, which is the time the funds have been delivered to the intended recipient in an amount that reflects the consideration the Company expects to be entitled to in exchange for services provided. The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) Revenue from Contracts with Customers (Topic 606), which includes the following steps: (1) identification of the contract with a customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, the Company satisfies a performance obligation. Revenue is derived from each transaction and varies based on the funding method chosen by the customer, the size of the transaction, the currency to be ultimately disbursed, the rate at which the currency was purchased, and the countries to which the funds are transferred. The Company’s contract with customers can be terminated by the customer without a termination penalty up until the time the funds have been delivered to the intended recipient. Therefore, the Company’s contracts are defined at the transaction level and do not extend beyond the service already provided. The Company’s service comprises a single performance obligation to complete transactions for the Company’s customers. Using compliance and risk assessment tools, the Company performs a transaction risk assessment on individual transactions to determine whether a transaction should be accepted. When the Company accepts a transaction and processes the designated payment method of the customer, the Company becomes obligated to its customer to complete the payment transaction. The Company recognizes transaction revenue on a gross basis as it is the principal for fulfilling payment transactions. As the principal to the transaction, the Company controls the service of completing payments on its payment platform. The Company bears primary responsibility for the fulfillment of the payment service, is the merchant of record, contracts directly with its customers, controls the product specifications, and defines the value proposition of its services. The Company is also responsible for providing customer support. Further, the Company has full discretion over determining the fee charged to its customers, which is independent of the cost it incurs in instances where it may utilize payment processors or other financial institutions to perform services on its behalf. These fees paid to payment processors and other financial institutions are recognized as transaction expenses in the consolidated statements of operations. The Company does not have any deferred contract acquisition costs.
