Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	1. Organization and Business Operations Organization and General AfterNext HealthTech Acquisition Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on April 12, 2021. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The Company was formed on April 12, 2021 and as of that date had not commenced operations. On May 3, 2021, the Company was funded with $25,000 for which it issued Founder Shares (as defined below). All activity for the period from April 12, 2021 (“Inception”) through December 31, 2022 relates to the Company’s formation, its initial public offering (“Public Offering”), which closed on August 16, 2021 (the “Close Date”), and the identification and evaluation of potential acquisition targets for a Business Combination. The Company will not generate operating revenues prior to the completion of the Business Combination and will generate non-operating income in the form of interest income on Permitted Investments (as defined below) from the proceeds derived from the Public Offering. The Company has selected December 31st as its fiscal year end. Going Concern If the Company does not complete an initial Business Combination within 24 months from the Close Date, the Company will (i) cease all operations except for the purposes of winding up, (ii) as promptly as reasonably possible, but not more than ten business days thereafter, redeem all of the Class A ordinary shares issued in the Public Offering at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account with Continental Stock Transfer and Trust Company acting as trustee (the “Trust Account”), including interest, net of taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish the shareholder rights of owners of Class A ordinary shares (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution, including Trust Account assets, will be less than the initial public offering price in the Public Offering. If a Business Combination is not completed within 24 months from the Close Date, the Company does not have sufficient cash flows to satisfy obligations to creditors upon liquidation and therefore, substantial doubt exists about the Company's ability to continue as a going concern. The accompanying financial statements have been prepared on a going concern basis and do not include any adjustments that might arise as a result of uncertainties about the Company’s ability to continue as a going concern. Sponsor The Company’s sponsor is AfterNext HealthTech Sponsor, Series LLC, a Delaware series limited liability company (the “Sponsor”). On May 3, 2021, the Sponsor purchased an aggregate of 20,000,000 Class F ordinary shares (“Founder Shares”) for an aggregate purchase price of $25,000, or approximately $0.001 per share. Prior to the Sponsor’s initial investment in the Company of $25,000, the Company had no assets. The purchase price per share of the Founder Shares was determined by dividing the amount of cash contributed to the Company by the Sponsor by the number of Founder Shares issued by the Company. Public Offering The Company intends to finance a Business Combination with proceeds from its Public Offering of units (“Units”) at a price of $10.00 per Unit, each consisting of one Class A ordinary share, $0.0001 par value, of the Company (“Class A ordinary shares”) and one-third of one redeemable warrant, and proceeds from the sale of private placement warrants at a price of $1.50 per warrant (“Private Placement Warrants”). The Trust Account Gross proceeds of $250,000,000 and $7,000,000 from the Public Offering and the sale of the Private Placement Warrants, respectively, less underwriting discounts of $5,000,000; and funds of $2,000,000 designated to pay the Company’s accrued formation and offering costs, ongoing administrative and acquisition search costs, plus repay notes payable of $750,000 to the Sponsor at the Close Date were placed in the Trust Account at the Close Date. On April 6, 2022 , the funds in the Trust Account were invested in specified U.S. government treasury bills with a maturity of 180 days or less and in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations (collectively “Permitted Investments”). Funds will remain in the Trust Account except for the withdrawal of interest earned on the funds that may be released to the Company to pay taxes and up to $100,000 of any dissolution expenses. The proceeds from the Public Offering and the sale of the Private Placement Warrants will not be released from the Trust Account until the earliest of (i) the completion of the Business Combination, (ii) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete the Business Combination within 24 months from the close of the Public Offering and (iii) the redemption of all of the Company’s Public Shares if it is unable to complete the Business Combination within 24 months from the close of the Public Offering, subject to applicable law. The remaining proceeds outside the Trust Account may be used to pay business, legal and accounting due diligence on prospective acquisitions, listing fees and continuing general and administrative expenses. Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating a Business Combination with (or acquisition of) a target business. Although the Company is not limited to, and may pursue targets in, any industry or geography, we intend to focus on industries that complement the Sponsor’s and management team’s background in technology, healthcare and related areas. As used herein, the target business must be with one or more target businesses that together have an aggregate fair market value equal to at least 80% of the balance in the Trust Account (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the Company signing a definitive agreement. After signing a definitive agreement for a Business Combination, the Company will provide the Public Shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares either (i) in connection with a shareholder meeting to approve the Business Combination or (ii) by means of a tender offer. Each Public Shareholder may elect to redeem their shares irrespective of whether they vote for or against the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes, divided by the number of then outstanding Public Shares, subject to the limitations described herein. The amount in the Trust Account is initially anticipated to be approximately $10.00 per Public Share. The per-share amount the Company will distribute to investors who properly redeem their shares will not be reduced by any deferred underwriting commissions payable to underwriters. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to sell their shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval under applicable law or stock exchange listing requirements. If the Company seeks shareholder approval, it will complete its Business Combination only if a majority of the outstanding Class A ordinary shares voted are voted in favor of the Business Combination. However, in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001, after payment of the deferred underwriting commission. In such an instance, the Company would not proceed with the redemption of its Public Shares and the related Business Combination, and instead may search for an alternate Business Combination. The Company has 24 months from the closing date of the Public Offering to complete its Business Combination. If the Company does not complete a Business Combination within this period, it shall (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The initial shareholders and the Company’s officers and directors have entered into a letter agreement with the Company, pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to complete the Business Combination within 24 months from the closing of the Public Offering. However, if the initial shareholders acquire Public Shares after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the Business Combination within the allotted 24-month time period. The underwriters have agreed to waive their rights to any deferred underwriting commission held in the Trust Account in the event the Company does not complete the Business Combination and those amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s Public Shares. If the Company fails to complete the Business Combination, the redemption of the Company’s Public Shares will reduce the book value of the shares held by the initial shareholders, who will be the only remaining shareholders after such redemptions. If the Company holds a shareholder vote or there is a tender offer for shares in connection with a Business Combination, a Public Shareholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes. As a result, such ordinary shares are recorded at their redemption amount and classified as temporary equity in accordance with ASC 480, “Distinguishing Liabilities from Equity.”

Organization and General

AfterNext HealthTech Acquisition Corp. (the “Company”) was incorporated as a Cayman Islands exempted company on April 12, 2021. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”).

The Company will not generate operating revenues prior to the completion of the Business Combination and will generate non-operating income in the form of interest income on Permitted Investments (as defined below) from the proceeds derived from the Public Offering. The Company has selected December 31st as its fiscal year end.

Going Concern

If the Company does not complete an initial Business Combination within 24 months from the Close Date, the Company will (i) cease all operations except for the purposes of winding up, (ii) as promptly as reasonably possible, but not more than ten business days thereafter, redeem all of the Class A ordinary shares issued in the Public Offering at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account with Continental Stock Transfer and Trust Company acting as trustee (the “Trust Account”), including interest, net of taxes (less up to $100,000 of such net interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish the shareholder rights of owners of Class A ordinary shares (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The accompanying financial statements have been prepared on a going concern basis and do not include any adjustments that might arise as a result of uncertainties about the Company’s ability to continue as a going concern.

Sponsor

The Company’s sponsor is AfterNext HealthTech Sponsor, Series LLC, a Delaware series limited liability company (the “Sponsor”). On May 3, 2021, the Sponsor purchased an aggregate of 20,000,000 Class F ordinary shares (“Founder Shares”) for an aggregate purchase price of $25,000, or approximately $0.001 per share. Prior to the Sponsor’s initial investment in the Company of $25,000, the Company had no assets. The purchase price per share of the Founder Shares was determined by dividing the amount of cash contributed to the Company by the Sponsor by the number of Founder Shares issued by the Company.

The Company intends to finance a Business Combination with proceeds from its Public Offering of units (“Units”) at a price of $10.00 per Unit, each consisting of one Class A ordinary share, $0.0001 par value, of the Company (“Class A ordinary shares”) and one-third of one redeemable warrant, and proceeds from the sale of private placement warrants at a price of $1.50 per warrant (“Private Placement Warrants”).

The Trust Account

Gross proceeds of $250,000,000 and $7,000,000 from the Public Offering and the sale of the Private Placement Warrants, respectively, less underwriting discounts of $5,000,000; and funds of $2,000,000 designated to pay the Company’s accrued formation and offering costs, ongoing administrative and acquisition search costs, plus repay notes payable of $750,000 to the Sponsor at the Close Date were placed in the Trust Account at the Close Date. On April 6, 2022 , the funds in the Trust Account were invested in specified U.S. government treasury bills with a maturity of 180 days or less and in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations (collectively “Permitted Investments”).

Funds will remain in the Trust Account except for the withdrawal of interest earned on the funds that may be released to the Company to pay taxes and up to $100,000 of any dissolution expenses. The proceeds from the Public Offering and the sale of the Private Placement Warrants will not be released from the Trust Account until the earliest of (i) the completion of the Business Combination, (ii) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend the amended and restated memorandum and articles of association to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete the Business Combination within 24 months from the close of the Public Offering and (iii) the redemption of all of the Company’s Public Shares if it is unable to complete the Business Combination within 24 months from the close of the Public Offering, subject to applicable law.

The remaining proceeds outside the Trust Account may be used to pay business, legal and accounting due diligence on prospective acquisitions, listing fees and continuing general and administrative expenses.

Business Combination

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating a Business Combination with (or acquisition of) a target business. Although the Company is not limited to, and may pursue targets in, any industry or geography, we intend to focus on industries that complement the Sponsor’s and management team’s background in technology, healthcare and related areas. As used herein, the target business must be with one or more target businesses that together have an aggregate fair market value equal to at least 80% of the balance in the Trust Account (less any deferred underwriting commissions and taxes payable on interest earned on the Trust Account) at the time of the Company signing a definitive agreement.

After signing a definitive agreement for a Business Combination, the Company will provide the Public Shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares either (i) in connection with a shareholder meeting to approve the Business Combination or (ii) by means of a tender offer. Each Public Shareholder may elect to redeem their shares irrespective of whether they vote for or against the Business Combination at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes, divided by the number of then outstanding Public Shares, subject to the limitations described herein. The amount in the Trust Account is initially anticipated to be approximately $10.00 per Public Share. The per-share amount the Company will distribute to investors who properly redeem their shares will not be reduced by any deferred underwriting commissions payable to underwriters. The decision as to whether the Company will seek shareholder approval of the Business Combination or will allow shareholders to sell their shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval under applicable law or stock exchange listing requirements. If the Company seeks shareholder approval, it will complete its Business Combination only if a majority of the outstanding Class A ordinary shares voted are voted in favor of the Business Combination. However, in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001, after payment of the deferred underwriting commission. In such an instance, the Company would not proceed with the redemption of its Public Shares and the related Business Combination, and instead may search for an alternate Business Combination.

The Company has 24 months from the closing date of the Public Offering to complete its Business Combination. If the Company does not complete a Business Combination within this period, it shall (i) cease all operations except for the purposes of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

However, if the initial shareholders acquire Public Shares after the Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the Business Combination within the allotted 24-month time period.

The underwriters have agreed to waive their rights to any deferred underwriting commission held in the Trust Account in the event the Company does not complete the Business Combination and those amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s Public Shares.

If the Company fails to complete the Business Combination, the redemption of the Company’s Public Shares will reduce the book value of the shares held by the initial shareholders, who will be the only remaining shareholders after such redemptions.

If the Company holds a shareholder vote or there is a tender offer for shares in connection with a Business Combination, a Public Shareholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes. As a result, such ordinary shares are recorded at their redemption amount and classified as temporary equity in accordance with ASC 480, “Distinguishing Liabilities from Equity.”
