Description Of Organisation And Business Operation [Abstract]
Description of organization and business operation disclosure	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Talkspace, Inc. (together with its consolidated subsidiaries, the “Company” or “Talkspace”) is a leading behavioral healthcare company enabled by a purpose-built technology platform. Talkspace provides individuals and licensed therapists, psychologists and psychiatrists with an online platform for one-on-one therapy delivered via messaging, audio and video. Talkspace, Inc. was originally incorporated as Hudson Executive Investment Corp. (“HEC”), a special purpose acquisition company, in Delaware on October 30, 2019 for the purpose of entering into a merger, share exchange, asset acquisition, stock purchase, recapitalization or other similar business combination with one or more businesses or entities. Business Combination On January 12, 2021, HEC, entered into an Agreement and Plan of Merger, dated as of January 12, 2021 (the “Merger Agreement”), with Groop Internet Platform, Inc. (“Old Talkspace”), Tailwind Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of HEC (“First Merger Sub”), and Tailwind Merger Sub II, LLC, a Delaware limited liability company (“Second Merger Sub”). On June 22, 2021, as contemplated by the Merger Agreement, First Merger Sub merged with and into Old Talkspace (the “First Merger”) with Old Talkspace surviving the First Merger, and immediately following the First Merger and as part of the same overall transaction as the First Merger, Old Talkspace merged with and into Second Merger Sub, with Second Merger Sub surviving the merger as a wholly owned subsidiary of HEC (the “Second Merger” and, together with the First Merger, the “Business Combination”). In connection with the Business Combination, HEC filed the Certificate of Incorporation and changed its name to “Talkspace, Inc.” The Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States (“GAAP”). Under this method of accounting, HEC who was the legal acquirer, is treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of Old Talkspace issuing stock for the net assets of HEC, accompanied by a recapitalization. The net assets of HEC are stated at historical cost, with no goodwill or other intangible assets recorded. Old Talkspace was determined to be the accounting acquirer based on the following predominant factors:  Old Talkspace’s shareholders represent a relative majority of the voting rights in the Company and have the ability to nominate the members of the board of directors for the Company;  Old Talkspace’s operations prior to the acquisition represent the ongoing operations of the Company; and  Old Talkspace’s senior management represents a majority of the senior management of the Company. The consolidated assets, liabilities and results of operations prior to the Business Combination are those of Old Talkspace. The shares and corresponding capital amounts and losses per share, prior to the Business Combination, have been retroactively restated based on shares reflecting the exchange ratio established in the Business Combination. See Note 3, “Business Combination,” for further details. Other On November 1, 2020, the Company completed an acquisition of Lasting, an app-based subscription for relationship and couple counseling for a total cash consideration of $ 10,685 . In addition, the Company entered into a non-competition agreement for a total consideration of $ 939 , which was recorded as an intangible asset. Operating Segments The Company operates its business in a single segment, which is how its chief operating decision maker, the Company’s Chief Executive Officer, reviews financial performance and allocates resources. The majority of the Company’s operations is based in the United States. COVID- 1 9 The global pandemic associated with COVID-19 has caused major disruption to all aspects of the global economy and daily life, particularly as quarantine and stay-at-home orders have been imposed by all levels of government. The Company has followed guidance by the United States, Israeli and other applicable foreign and local governments to protect its employees and operations during the pandemic and has implemented a remote environment for its business. The Company cannot predict the potential impacts of the COVID-19 pandemic on its business or operations, but continuously monitors performance and other industry reports to assess the risk of future negative impacts as the disruptions of the COVID-19 pandemic continue to evolve.

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2. SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. The Company’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2020, have been applied consistently in these unaudited condensed consolidated financial statements, unless otherwise stated. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the years ended December 31, 2020 and 2019 included in the Company’s final prospectus filed with the Securities and Exchange Commission (“SEC”) pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on July 13, 2021 (the “Prospectus”). Reclassifications The Company has made certain reclassifications to prior period amounts to conform to the current period presentation within the accompanying condensed consolidated financial statements and notes to the condensed consolidated financial statements. Use of estimates The preparation of consolidated financial statements, in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, it is eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with certain other public companies difficult or impossible because of the potential differences in accounting standards used. Recently adopted accounting standards In February 2016, the FASB issued ASU 2016-02, Topic 842 “Leases”. This ASU clarifies the definition of a lease and requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-to-use asset representing its right to use the underlying asset for the lease term. In November 2019, the FASB issued ASU 2020-05 which extends the effective date of ASU 2016-02 for non-public business entities, including smaller reporting companies, to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The Company adopted ASC 842 on January 1, 2021 and did not restate comparative periods. In addition, the Company elected the available practical expedients on adoption. The Company determines if an arrangement is a lease at inception. Lease classification is governed by five criteria in ASC 842-10-25-2. If any of these five criteria is met, the Company classifies the lease as a finance lease. Otherwise, the Company classifies the lease as an operating lease. As of June 30, 2021, all arrangements were classified as operating leases. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of the lease payments. Operating lease expenses are recognized on a straight-line basis over the lease term. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption for all leases with a term shorter than 12 months. This means that for those leases, the Company does not recognize ROU assets or lease liabilities, including not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition, but recognizes lease expenses over the lease term on a straight-line basis. The Company also elected the practical expedient to not separate lease and non-lease components for all of the Company’s leases. The Company does not currently have any leases with terms in excess of 12 months. The Company adopted this ASU with no impact on its financial statements or related footnotes.

Business Combinations [Abstract]
Business Combination	NOTE 3. BUSINESS COMBINATION As discussed in Note 1, on June 22, 2021, the Company completed the Business Combination pursuant to the Merger Agreement dated January 12, 2021 . The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, HEC, who was the legal acquirer, was treated as the “acquired” company for financial reporting purposes. Accordingly, the Business Combination was treated as the equivalent of Old Talkspace issuing stock for the net assets of HEC, accompanied by a recapitalization. The net assets of HEC are stated at historical cost, with no goodwill or other intangible assets recorded. Upon the Closing, among other things, all shares of Old Talkspace’s Common Stock, par value $ 0.001 per share (the “Old Talkspace Common Stock”), all shares of Old Talkspace’s Series Seed Preferred Stock, par value $ 0.001 per share, Series Seed-1 Preferred Stock, par value $ 0.001 per share, Series Seed-2 Preferred Stock, par value $ 0.001 per share, Series A Preferred Stock, par value $ 0.001 per share, Series B Preferred Stock, par value $ 0.001 per share, Series C Preferred Stock, par value $ 0.001 per share and Series D Preferred Stock, par value $ 0.001 per share (collectively, the “Old Talkspace Preferred Stock” and, together with the Old Talkspace Common Stock, the “Old Talkspace Capital Stock”) and all vested options exercisable for Old Talkspace Common Stock (“Old Talkspace Vested Options”) outstanding as of immediately prior to Closing were cancelled or assumed, as applicable, and converted into the right to receive, at the election of the holders thereof, a number of shares of Talkspace’s Common Stock, par value $ 0.0001 per share (the “Talkspace common stock”) (or, with respect to holders of Old Talkspace Vested Options, a number of vested options exercisable for Talkspace common stock “Talkspace Vested Options”) or a combination of shares of Talkspace common stock and cash (or, with respect to holders of Old Talkspace Vested Options, a combination of Talkspace Vested Options and cash), in each case, as adjusted pursuant to the Merger Agreement, which, in the aggregate with the unvested options exercisable for Old Talkspace Common Stock assumed by Talkspace and converted into unvested options exercisable for Talkspace common stock, equaled approximately $ 199.3 million in cash and 109,461,534 shares of Talkspace common stock (at a deemed value of $ 10.00 per share). The 109,461,534 shares consisted of 91,473,779 shares issued to holders of Old Talkspace capital stock and 17,987,755 options to purchase Talkspace common stock issued to holders of Old Talkspace stock options. The exchange ratio of 1.134140 was used to convert Old Talkspace capital stock and stock options into Talkspace capital stock and stock options. In connection with the Business Combination, a number of investors (each, a “Subscriber”) purchased from the Company an aggregate of 30,000,000 shares of common stock (the “PIPE”), for a purchase price of $ 10.00 per share and an aggregate purchase price of $ 300.0 million (the “PIPE Shares”), pursuant to separate subscription agreements (each, a “Subscription Agreement”) entered into effective as of January 12, 2021. In addition, in connection with the execution of the Merger Agreement, Talkspace entered into an amendment to the forward purchase agreement (as amended, the “Forward Purchase Agreement”) with HEC Master Fund LP, a Delaware limited partnership and affiliate of the Sponsor (“HEC Fund”), dated June 8, 2020. Pursuant to the Forward Purchase Agreement, HEC Fund agreed to purchase 2,500,000 forward purchase units, consisting of one share of HEC’s Class A common stock and one-half of one warrant to purchase one share of HEC’s Class A common stock, for $ 10.00 per unit, or an aggregate amount of $ 25.0 million, in a private placement that would close concurrently with the Closing and to backstop up to $ 25.0 million of redemptions by stockholders of HEC (the “Forward Purchase”). Immediately after giving effect to the redemption of 25,968,043 shares of HEC’s Class A common stock in connection with the Business Combination, the Forward Purchase and the PIPE Investment, there were 152,255,736 shares of Talkspace common stock and 33,480,000 warrants to purchase Talkspace common stock (the “Talkspace warrants”) outstanding. Upon the consummation of the Business Combination, HEC’s Class A common stock, warrants and units ceased trading on The Nasdaq Stock Market LLC (the “Nasdaq”), and Talkspace common stock and Talkspace warrants began trading on June 23, 2021 on Nasdaq under the symbols “TALK” and “TALKW,” respectively. Upon the closing of the Business Combination, the Company’s certificate of incorporation was amended and restated to, among other things, increase the total number of authorized shares of common stock to 1,000,000,000 shares, $ 0.0001 par value per share, and authorized shares of preferred stock to 100,000,000 , $ 0.0001 par value per share. Public Warrants and Private Placement Warrants As a result of the Business Combination, the Company assumed the outstanding Public Warrants to purchase 20,700,000 shares of the Company’s common stock and the outstanding Private Placement Warrants to purchase 10,280,000 shares of the Company’s common stock. Additionally, the Company issued 2,500,000 Private Placement Warrants at Closing pursuant to the Forward Purchase Agreement with HEC Fund as described above. Each whole Warrant entitles the registered holder to purchase one share of the Company’s common stock at a price of $ 11.50 per share, at any time commencing 30 days after the closure of the Business Combination. The warrants expire five years after the completion of the Business Combination. Redemption of Warrants for Cash Once the Public Warrants become exercisable, the Company may call the Public Warrants for redemption:  in whole and not in part;  at a price of $ 0.01 per warrant;  upon a minimum of thirty (30) days’ prior written notice of redemption, or the thirty (30)-day redemption period, to each warrant holder; and  if, and only if, the closing price of our common stock equals or exceeds $ 18.00 per share (as adjusted for stock splits, stock recapitalizations, reorganizations, recapitalizations and the like) for any twenty (20) trading days within a thirty (30)-trading day period ending on the third business day prior to the date on which we send the notice of redemption to the warrant holders. When the Public Warrants become redeemable, the Company may exercise the redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws. If the Company calls the Public Warrants for redemption for cash, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of common stock at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the warrants. The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of common stock issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or saleable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable for cash or on a cashless basis, at the holder’s option, and be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company determined the Public Warrants met the criteria to be classified as equity in accordance with ASC 815-40. The Company valued these warrants using the instrument’s publicly listed trading price on the date of acquisition and included $ 27.9 million related to these warrants in additional paid-in capital within stockholder’s deficit. The Private Placement Warrants are accounted for as liabilities in accordance with ASC 815-40. As of June 30, 2021 , the Company included $ 38.9 million within warrant liabilities in the accompanying condensed consolidated balance sheets. Refer to Note 5, “Fair Value Measurement” for additional information.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 5. FAIR VALUE MEASUREMENT The Company applies ASC 820, “Fair Value Measurements and Disclosures”. Under this standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various valuation approaches. ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the inputs as follows: Level 1: Valuations based on quoted prices in active markets for identical assets that the Company has the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2: Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3: Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. In connection with the consummation of the Business Combination, the Company acquired Private Placement Warrants from HEC. Additionally, there were Private Placement Warrants that were issued related to the closure of the Forward Purchase Agreement with the HEC Fund as described in Note 3. The Company measures its Private Placement Warrants at fair value on a recurring basis. The Private Placement Warrants were valued using a Modified Black Scholes Model, which is considered to be a Level 3 fair value measurement. The primary unobservable input utilized in determining the fair value of the Private Placement Warrants is the expected volatility of the Company’s common stock. The expected volatility of the Company’s common stock was estimated to be approximately 50 %. Prior to the Business Combination, Old Talkspace had issued warrants to purchase its common stock and its Series D preferred stock. In connection with the Business Combination, the warrants to purchase Old Talkspace’s common stock and its Series D preferred stock were exercised and converted into common shares of the Company during the quarter ended June 30, 2021. As of December 31, 2020, there were 60,000 outstanding warrants to purchase the Old Talkspace’s common stock for a price of $ 0.44 per share and 50,881 outstanding warrants to purchase the Company’s preferred D stock for a price of $ 2.75 per share. The inputs related to Old Talkspace’s share prices prior to the Business Combination were determined based on management’s assumptions and based on the Option Pricing Model (“OPM”). The fair value of the underlying preferred share price was determined by the board of directors, considering among others, a third-party valuation. These inputs were considered to be a Level 3 measurement. The following table presents information about the Company’s liabilities that are measured at fair value on a recurring basis at June 30, 2021 and December 31, 2020 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value. Level June 30, 2021 December 31, 2020 Liabilities: Warrant liability – Private Placement Warrants 3 $ 38,897 $ - Warrant liability – warrants to purchase Old Talkspace’s preferred D shares 3 - 444 The Private Placement Warrants are accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liabilities in the accompanying condensed consolidated balance sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within the change in fair value of warrant liabilities in the condensed consolidated statement of operations and comprehensive loss. The following table presents the changes in the fair value of warrant liabilities: Private Placement Old Talkspace Warrants Balance at December 31, 2020 $ - $ 444 Acquired in Business Combination 32,399 - Issued in connection with closure of the Forward Purchase Agreement 7,879 - Change in value ( 1,381 ) 165 Converted into equity - ( 609 ) Balance at June 30, 2021 $ 38,897 $ - In connection with the consummation of the Business Combination, the Company also acquired Public Warrants from HEC and also issued equity warrants to certain consultants. The Company determined these warrants met the criteria to be classified as equity in accordance with ASC 815-40. The Company valued these warrants using the instrument’s publicly listed trading price on the date of acquisition or issuance, where applicable, and included in additional paid-in capital within stockholder’s deficit. This is considered to be a non-recurring Level 1 measurement due to the use of an observable market quote in an active market.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	NOTE 9. SHARE-BASED COMPENSATION The Company adopted the 2014 Stock Incentive Plan (the “2014 Plan”) pursuant to which incentive and nonqualified stock options and stock purchase rights to purchase the Company’s common stock may be granted to officers, employees, directors, consultants and service providers. In connection with the closing of the Business Combination, the Company adopted the 2021 Incentive Award Plan (the “2021 Plan”) under which the Company may grant cash and equity incentive awards to eligible service providers in order to attract, motivate and retain the talent. In connection with the effectiveness of the 2021 Plan, no further awards will be granted under the 2014 Plan. Employees, consultants and directors of the Company, and employees and consultants of its subsidiaries, are eligible to receive awards under the 2021 Plan. The 2021 Plan is administered by the Company’s board of directors, which may delegate its duties and responsibilities to one or more committees of the Company’s directors and/or officers (referred to collectively as the “plan administrator”), subject to the limitations imposed under the 2021 Plan, Section 16 of the Securities Exchange Act of 1934, as amended, stock exchange rules and other applicable laws. The plan administrator has the authority to take all actions and make all determinations under the 2021 Plan, to interpret the 2021 Plan and award agreements and to adopt, amend and repeal rules for the administration of the 2021 Plan as it deems advisable. The plan administrator also has the authority to determine which eligible service providers receive awards, grant awards and set the terms and conditions of all awards under the 2021 Plan, including any vesting and vesting acceleration provisions, subject to the conditions and limitations in the 2021 Plan. An initial aggregate of 15,565,074 shares of Talkspace common stock are available for issuance under the 2021 Plan and the maximum number of shares of Talkspace common stock that may be issued pursuant to the exercise of incentive stock options granted under the 2021 Plan is 100,000,000 .

Income Tax Disclosure [Abstract]
Taxes on Income	NOTE 11. TAXES ON INCOME As a result of the Company’s history of net operating losses (“NOL”), the Company has provided for a full valuation allowance against its deferred tax assets for assets that are not more-likely-than-not to be realized. The main reconciling item between the statutory tax rate of the Company and the effective tax rate is the recognition of valuation allowance in respect of deferred taxes relating to accumulated net operating losses carried forward due to the uncertainty of the realization of such deferred taxes.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). In management’s opinion, the unaudited condensed consolidated financial statements reflect all adjustments of a normal recurring nature that are necessary for a fair presentation of the results for the interim periods presented. The Company’s interim period results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2020, have been applied consistently in these unaudited condensed consolidated financial statements, unless otherwise stated. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the years ended December 31, 2020 and 2019 included in the Company’s final prospectus filed with the Securities and Exchange Commission (“SEC”) pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, on July 13, 2021 (the “Prospectus”).
Reclassifications	Reclassifications The Company has made certain reclassifications to prior period amounts to conform to the current period presentation within the accompanying condensed consolidated financial statements and notes to the condensed consolidated financial statements.
Use of estimates	Use of estimates The preparation of consolidated financial statements, in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The Company evaluates its assumptions on an ongoing basis. The Company’s management believes that the estimates, judgment, and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Emerging growth company	Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, it is eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with certain other public companies difficult or impossible because of the potential differences in accounting standards used.
Recently adopted accounting standards	Recently adopted accounting standards In February 2016, the FASB issued ASU 2016-02, Topic 842 “Leases”. This ASU clarifies the definition of a lease and requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-to-use asset representing its right to use the underlying asset for the lease term. In November 2019, the FASB issued ASU 2020-05 which extends the effective date of ASU 2016-02 for non-public business entities, including smaller reporting companies, to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The Company adopted ASC 842 on January 1, 2021 and did not restate comparative periods. In addition, the Company elected the available practical expedients on adoption. The Company determines if an arrangement is a lease at inception. Lease classification is governed by five criteria in ASC 842-10-25-2. If any of these five criteria is met, the Company classifies the lease as a finance lease. Otherwise, the Company classifies the lease as an operating lease. As of June 30, 2021, all arrangements were classified as operating leases. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of the lease payments. Operating lease expenses are recognized on a straight-line basis over the lease term. The new standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption for all leases with a term shorter than 12 months. This means that for those leases, the Company does not recognize ROU assets or lease liabilities, including not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition, but recognizes lease expenses over the lease term on a straight-line basis. The Company also elected the practical expedient to not separate lease and non-lease components for all of the Company’s leases. The Company does not currently have any leases with terms in excess of 12 months. The Company adopted this ASU with no impact on its financial statements or related footnotes.
