Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles 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. Accordingly, they do not include all disclosures normally required in annual financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 , which was filed with the SEC on March 31, 2023 . In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as its annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of June 30, 2023, results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' equity for the three and six months ended June 30, 2023 and 2022. The results of operations for the three and six months ended June 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. Emerging Growth Company The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, EGCs can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. The Company expects to use the extended transition period for any other new or revised accounting standards during the period in which it remains an EGC. Segment Information The Company has a single operating and reportable segment. In reaching this conclusion, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources, and assess performance. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on an aggregated basis for purposes of making operating decisions, assessing financial performance and allocating resources. Significant accounting policies The Company’s significant accounting policies are disclosed in the Company’s audited financial statements and related notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2022 , which was filed with the SEC on March 31, 2023. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Such estimates and assumptions include the costs to be capitalized as internal-use software, which include determining (i) whether projects will result in new or additional functionality, (ii) the start and end date of the application development phase of projects, and (iii) their useful life, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, expected lease term, lease and non-lease component allocation, estim ates related to variable consideration in revenue arrangements, valuation of the Company’s (i) stock options, and (ii) Employee Stock Purchase Plan (“ESPP”) expense, and accounting for taxes, including estimates for indirect tax liability , deferred tax assets, valuation allowance and uncertain tax positions. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Future actual results could differ materially from these estimates. Foreign Currency The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company and its subsidiaries is USD. Transaction gains and losses that arise from exchange rate fluctuations on monetary transactions denominated in a currency other than the functional currency are included in general and administrative on the condensed consolidated statements of operations when realized. Concentrations Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, short-term investments, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and short-term investments with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the balance sheets. In addition, the Company uses City National Bank, a subsidiary of Royal Bank of Canada (“RBC”), for its banking needs. While the Company and its bank has not been directly affected by the recent failures of certain banks, the banking industry overall has experienced disruption and uncertainty, which could put additional pressures on the Company’s bank and other banks, and may negatively impact the availability and costs for various banking and investment offerings. Vendors. The Company acquires infrastructure equipment from third-party vendors. Vendors may have limited sources of equipment and supplies, which may expose the Company to potential supply and service disruptions that could harm the Company’s busine ss.

The Company derives substantially all of its revenue from the services operating on its Backblaze Storage Cloud platform: its Backblaze B2 Cloud Storage (“Backblaze B2”) and Backblaze Computer Backup (“Computer Backup”) offerings. The potential for severe impact to the Company’s business could result if the Company was unable to operate its platform or serve customers through its platform for an extended period of time. Restructuring Restructuring costs are comprised of severance costs related to workforce reductions. The Company recognizes restructuring charges when the liability is incurred. For involuntary terminations, employee termination benefits are accrued at the date management has committed to a plan of termination and employees have been notified of their termination dates and expected severance payments. For voluntary terminations, the Company recognizes a liability when the termination benefit has been irrevocably accepted by the employee. Investments The Company holds all investments on a held-to-maturity basis, and they are reported at amortized cost with realized gains or losses reported in earnings. The Company determines the appropriate classification of its investment in debt securities at the time of purchase and re-evaluates such determination at each balance sheet date. The Company’s short-term investments include investment grade commercial paper with original maturities of 365 days or less at the date of purchase. Short-term investments are recorded at amortized cost on the balance sheet. Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which requires a financial asset measured at an amortized cost basis to be presented at the net amount expected to be collected, with further clarifications made more recently. For trade receivables, unbilled receivables, loans and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2023 using the modified retrospective transition method with comparative periods continuing to be reported using the previous applicable guidance and determined that it did not have a material impact on its condensed consolidated financial statements.

Deferred Revenue Deferred revenue was $25.8 million and $25.5 million as of June 30, 2023 and December 31, 2022, respectively. Revenue recognized for the three months ended June 30, 2023 and 2022 was $9.6 million and $9.0 million, respectively, and was $15.9 million and $14.8 million for the six months ended June 30, 2023 and 2022, respectively, which was included in each deferred revenue balance at the beginning of each respective period.

ESPP In October 2021, the Company’s Board of Directors adopted the 2021 Employee Stock Purchase Plan (“ESPP”), which became effective on the date of the IPO. At its inception, the ESPP reserved and authorized the issuance of up to a total of 956,800 shares of Class A common stock to participating employees. Pursuant to its evergreen provision, the Company increased the number of shares reserved under the ESPP by 667,874 and 607,696 during January 2023 and 2022, respectively. During the six months ended June 30, 2023, 348,555 shares of Class A common stock have been purchased under the ESPP. The fair value of the purchase rights under the ESPP was estima ted using the Black-Scholes option pricing model with a similar methodology for determining inputs as the Company’s stock options, as described above. The Company recorded stock-based compensation expense under this plan of $0.9 million and $0.7 million for the three months ended June 30, 2023 and 2022, respectively, of which the Company capitalized $0.2 million and $0.1 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software. The Company recorded stock-based compensation expense under this plan of $1.9 million and $1.5 million for the six months ended June 30, 2023 and 2022, respectively, of which the Company capitalized $0.4 million and $0.2 million, respectively, of stock-based compensation expense under this plan for the development of internal-use software. As of June 30, 2023, the total unrecognized stock-based compensation expense related to the ESPP was $2.8 million and is expected to be recognized over a weighted average period of one year. As of June 30, 2023, $0.4 million had been withheld on behalf of employees, respectively. The following table summarizes the Black-Scholes option pricing model assumptions used in estimating the fair value of the stock purchase rights under the ESPP during the three and six months ended June 30, 2023 and 2022, respectively.

As of June 30, 2023, total compensation cost related to stock options and RSUs not yet vested was $15.5 million and $21.6 million, respectively, which will be recognized over a weighted-average period of two d RSUs, respectively. Bonus Plan During March 2022, the Company’s Compensation Committee approved a new bonus structure (“Bonus Plan”) for its employees. The Bonus Plan is contingent upon the achievement of 2022 corporate performance targets. Pursuant to the Bonus Plan, during February 2023 the Company’s Compensation Committee approved the issuance of approximately 288,000 RSUs that immediately vested. The Company recognized $0.6 million and $1.0 million in stock-based compensation during the three and six months ended June 30, 2022, respectively. During February 2023, the Company’s Board of Directors approved 2023 corporate performance targets under its Bonus Plan for its employees. If these performance targets are met during 2023, employees will be paid out under the plan in RSUs in 2024. As a result, the Company recognized $0.3 million and $0.9 million in stock-based compensation during the three and six months ended June 30, 2023, respectively, based on progress made towards these performance targets.

Earnings Per Share [Abstract]
Net Loss per Share Attributable to Common Stockholders	Net Loss per Share Attributable to Common StockholdersThe Company computes net loss per share using the two-class method required for multiple classes of common stock and participating securities. The rights of the holders of the Class A common stock and Class B common stock are identical, except with respect to voting and conversion. Accordingly, the Class A common stock and Class B common stock share equally in the Company’s net losses. Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share attributable to commo n stockholders is computed by giving effect to all potentially dilutive common stock equivalents during the period. For purposes of this calculation, the Company’s stock options, share purchase rights pursuant to the Company’s ESPP, and unv ested restricted stock are considered to be potential common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive. The following table presents the calculation of basic and diluted net loss per share (in thousands, except share and per share data): Three Months Ended June 30, Six Months Ended June 30, 2023 2022 2023 2022 Class A Class B Class A Class B Class A Class B Class A Class B Numerator: Net loss attributable to common stockholders $ (8,981) $ (5,356) $ (4,751) $ (6,824) $ (18,428) $ (13,022) (8,328) $ (15,777) Denominator for basic and diluted net loss per share: Weighted-average shares used in computing net loss per share attributable to common stockholders – basic and diluted 22,016,693 13,132,307 12,799,289 18,383,625 20,237,805 14,301,424 10,662,842 20,201,357 Net loss per share attributable to common stockholders – basic and diluted $ (0.41) $ (0.41) $ (0.37) $ (0.37) $ (0.91) $ (0.91) $ (0.78) $ (0.78) Since the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive. The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented are as follows: June 30, 2023 2022 RSUs 3,742,337 1,205,401 Stock options 10,970,322 13,803,643 Shares issuable pursuant to the ESPP 123,593 101,790 Total 14,836,252 15,110,834

Restructuring and Related Activities [Abstract]
Restructuring	RestructuringIn January 2023, the Company initiated measures to reduce headcount to pursue greater cost efficiency and align strategic initiatives. These measures were substantially completed during the six months ended June 30, 2023, and the total cost was $3.6 million. During the six months ended June 30, 2023, approximately 1% and 4% of the Company’s workforce terminated employment, which were voluntary and involuntary terminations, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company is subject to U.S. federal and state income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter. The effective tax rate for each of the three and six months ended June 30, 2023 and 2022 was zero as the Company has incurred continuous operating losses. The Company recorded no income tax provision or benefit during the six months ended June 30, 2023.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles 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. Accordingly, they do not include all disclosures normally required in annual financial statements prepared in accordance with GAAP. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes for the year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 , which was filed with the SEC on March 31, 2023 . In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as its annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of June 30, 2023, results of operations for the three and six months ended June 30, 2023 and 2022, cash flows for the six months ended June 30, 2023 and 2022, and stockholders' equity for the three and six months ended June 30, 2023 and 2022. The results of operations for the three and six months ended June 30, 2023 and 2022 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.
Segment Information	Segment Information The Company has a single operating and reportable segment. In reaching this conclusion, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources, and assess performance. The Company’s chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on an aggregated basis for purposes of making operating decisions, assessing financial performance and allocating resources.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Such estimates and assumptions include the costs to be capitalized as internal-use software, which include determining (i) whether projects will result in new or additional functionality, (ii) the start and end date of the application development phase of projects, and (iii) their useful life, the useful lives of other long-lived assets, impairment considerations for long-lived assets, the incremental borrowing rate for lease agreements, expected lease term, lease and non-lease component allocation, estim ates related to variable consideration in revenue arrangements, valuation of the Company’s (i) stock options, and (ii) Employee Stock Purchase Plan (“ESPP”) expense, and accounting for taxes, including estimates for indirect tax liability , deferred tax assets, valuation allowance and uncertain tax positions. The Company bases its estimates on historical experience and on assumptions that management considers reasonable. Future actual results could differ materially from these estimates.
Foreign Currency	Foreign Currency The reporting currency of the Company is the United States dollar (“USD”). The functional currency of the Company and its subsidiaries is USD. Transaction gains and losses that arise from exchange rate fluctuations on monetary transactions denominated in a currency other than the functional currency are included in general and administrative on the condensed consolidated statements of operations when realized.
Concentrations	Concentrations Credit risk. Financial instruments that potentially subject the Company to credit risk primarily consist of cash, cash equivalents, accounts receivable, short-term investments, and unbilled accounts receivable. The Company maintains its cash, restricted cash, and short-term investments with high-quality financial institutions with investment-grade ratings. In the event of a failure of any financial institutions where the Company maintains deposits, it may lose timely access to its funds at such institutions and incur significant losses to the extent its funds exceed the $250,000 limit insured by the Federal Deposit Insurance Corporation. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. For accounts receivable, the Company is exposed to credit risk in the event of nonpayment by customers to the extent of the amount recorded on the balance sheets. In addition, the Company uses City National Bank, a subsidiary of Royal Bank of Canada (“RBC”), for its banking needs. While the Company and its bank has not been directly affected by the recent failures of certain banks, the banking industry overall has experienced disruption and uncertainty, which could put additional pressures on the Company’s bank and other banks, and may negatively impact the availability and costs for various banking and investment offerings. Vendors. The Company acquires infrastructure equipment from third-party vendors. Vendors may have limited sources of equipment and supplies, which may expose the Company to potential supply and service disruptions that could harm the Company’s busine ss.

The Company derives substantially all of its revenue from the services operating on its Backblaze Storage Cloud platform: its Backblaze B2 Cloud Storage (“Backblaze B2”) and Backblaze Computer Backup (“Computer Backup”) offerings. The potential for severe impact to the Company’s business could result if the Company was unable to operate its platform or serve customers through its platform for an extended period of time.
Restructuring	Restructuring Restructuring costs are comprised of severance costs related to workforce reductions. The Company recognizes restructuring charges when the liability is incurred. For involuntary terminations, employee termination benefits are accrued at the date management has committed to a plan of termination and employees have been notified of their termination dates and expected severance payments. For voluntary terminations, the Company recognizes a liability when the termination benefit has been irrevocably accepted by the employee.
Investments	Investments The Company holds all investments on a held-to-maturity basis, and they are reported at amortized cost with realized gains or losses reported in earnings. The Company determines the appropriate classification of its investment in debt securities at the time of purchase and re-evaluates such determination at each balance sheet date.
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which requires a financial asset measured at an amortized cost basis to be presented at the net amount expected to be collected, with further clarifications made more recently. For trade receivables, unbilled receivables, loans and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. The Company adopted the guidance effective January 1, 2023 using the modified retrospective transition method with comparative periods continuing to be reported using the previous applicable guidance and determined that it did not have a material impact on its condensed consolidated financial statements.
