| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| The Company | The Company NeuroPace, Inc., or the Company, was incorporated in the state of Delaware on November 19, 1997. The Company is a medical device company that has developed the RNS System, the only commercially available brain-responsive neuromodulation system designed for treating drug-resistant focal epilepsy by delivering personalized, real-time treatment at the seizure source. The Company began commercializing its products in the United States in 2014. At-the-Market Equity Offering In November 2022, the Company filed a shelf registration statement on Form S-3 with the Securities Exchange Commission, or the SEC, for up to $150.0 million of securities, including up to $50.0 million under an at-the-market, or ATM, equity program pursuant to a sales agreement with Leerink Partners LLC, or Leerink (formerly SVB Securities LLC). The Company agreed to pay Leerink commissions of up to 3.0% of the gross proceeds. The Company’s common stock were issued at prevailing market prices. In January 2025, the Company sold 18,590 shares under the ATM program for net proceeds of $0.2 million. In February 2025, the Company terminated the Sales Agreement and the ATM program. At termination, $38.3 million remained available under the ATM program. Follow-On Offering In February 2025, the Company completed a follow-on offering of 7,475,000 shares of common stock, including 975,000 shares issued upon exercise of the underwriters’ option, at $10.00 per share. The net proceeds were $69.7 million after underwriting discounts, commissions and offering expenses. The Company used $49.5 million of the net proceeds to repurchase all of the 5,270,845 shares held by its significant stockholder (a related party), KCK Ltd., at $9.40 per share. The repurchased shares became authorized but unissued shares. Liquidity and Capital Resources The Company has incurred operating losses and negative cash flows from operations since its inception and had an accumulated deficit of $559.1 million as of March 31, 2026. For the three months ended March 31, 2026 and 2025, the Company used $5.9 million and $7.5 million of cash in its operating activities, respectively. As of March 31, 2026, the Company had cash, cash equivalents and short-term investments of $54.0 million. Historically, the Company has funded its operations principally through the sales of its products, issuance of equity securities and debt financing. The Company’s condensed financial statements have been prepared on the basis of the Company continuing as a going concern for the next 12 months. Management believes that the Company’s cash, cash equivalents and short-term investments will allow the Company to continue its planned operations for at least the next 12 months from the date of the issuance of these unaudited interim condensed financial statements. The MidCap Credit Agreement (see Note 6) financial covenants require the Company to maintain an Applicable Liquidity Threshold no less than (a) $60.0 million until June 30, 2027, and (b) $40.0 million thereafter; or provided the Company earns at least $90.0 million net revenue from the RNS System in 2026, liquidity shall be no less than $35.0 million thereafter. If liquidity falls below the Applicable Liquidity Threshold, the Company must satisfy minimum annual trailing net RNS System revenue, tested quarterly, starting from $69.2 million over a trailing 12-month period ending June 30, 2025, and increasing to $87.3 million for the trailing 12-month period ending March 31, 2030. The Company’s trailing 12-month net RNS System revenue was $85.2 million as of March 31, 2026, exceeding the $71.9 million minimum per the MidCap Credit Agreement. The MidCap Credit Agreement also requires the Company to maintain a Minimum Liquidity balance of $25.0 million. Liquidity is defined as cash and cash equivalents, short-term investments, and following the initial borrowing under the Revolver (see Note 6), the available Revolver balance. Failure to comply with these covenants could result in acceleration of the debt and requires the Company to obtain additional capital and may raise doubt about the Company’s ability to continue as a going concern. As of March 31, 2026, the Company was in compliance with all covenants of the MidCap Credit Agreement.

| Accounting Policies [Abstract] | |
| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The unaudited interim condensed financial statements have been prepared in conformity with generally accepted accounting principles in the United States, or GAAP. Unaudited Interim Financial Information The condensed balance sheet as of December 31, 2025 was derived from the Company’s audited financial statements, but does not include all disclosures required by GAAP. The accompanying unaudited condensed financial statements as of March 31, 2026 and for the three months ended March 31, 2026 and 2025, have been prepared by the Company, pursuant to the rules and regulations of the SEC for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2025 and notes thereto, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC on March 3, 2026. In the opinion of management, all normal recurring adjustments necessary for a fair presentation have been included. The results for the three months ended March 31, 2026 are not necessarily indicative of the results for the year ending December 31, 2026. Use of Estimates The preparation of unaudited interim condensed financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts and disclosures. The Company uses significant judgments when making estimates related to the provision for excess and obsolete inventories. Actual results may ultimately materially differ from these estimates and assumptions. Concentration of Credit Risk, and Other Risks and Uncertainties Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents, short-term investments and accounts receivable to the extent of the amounts recorded on the balance sheets. The Company’s accounts receivable, with the exception of $0.1 million, are due from a variety of health care organizations in the United States. For the three months ended March 31, 2026 and 2025, there were no customers that represented 10% or more of revenue. As of March 31, 2026 and December 31, 2025, no customer represented 10% or more of the Company’s accounts receivable. Remaining Performance Obligation and Contract Liabilities The Company’s contract liabilities consist of deferred revenue of $0.1 million as of March 31, 2026 and December 31, 2025. Revenue recognized during the three months ended March 31, 2026 and March 31, 2025 that was included in the deferred revenue balance at the beginning of the year was $0.1 million and $0.2 million, respectively. As of March 31, 2026, the aggregate amount of the transaction price allocated to the remaining performance obligations that are unsatisfied or partially unsatisfied was $1.9 million, which the Company expects to recognize as revenue by June 2028 pursuant to customer contract terms. Government Programs The Company continues to receive funding under its National Institutes of Health, or NIH, grant and recognizes funding as a reduction in research and development expenses in an amount equal to the qualifying expenses incurred in each period up to the amount awarded by the NIH. The Company received $0.2 million and $0.1 million in funding during the three months ended March 31, 2026 and 2025, respectively. Qualifying expenses incurred by the Company in advance of funding by the NIH are recorded within prepaid expenses and other current assets on the balance sheets. As of March 31, 2026, the Company recorded prepaid expenses and other current assets of less than $0.1 million related to the fifth year of funding. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In July 2025, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2025-05, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, providing a practical expedient to measure credit losses on current accounts receivable and current contract assets under Accounting Standards Codification 606, Revenue from Contracts with Customers. The practical expedient assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This ASU is effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods and should be applied prospectively. The Company adopted this ASU effective January 1, 2026. The adoption of this ASU did not have an impact on the Company’s financial statements and related disclosures. Recent Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosure (Subtopic 220-40): Clarifying the Effective Date. ASU 2024-03 is intended to provide more detailed information about specified categories of expenses (including employee compensation, depreciation, and amortization) included in certain expense captions presented on the face of the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted, and may be applied either prospectively to financial statements issued for reporting periods after its effective date or retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact this standard will have on its financial statement disclosures. In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities, providing authoritative guidance on the recognition, measurement, presentation, and disclosure of government grants received by business entities. The standard introduces a framework for determining when grants should be recognized, distinguishing between asset-related and income-related grants, and allows entities to present grants either as a reduction of related expenses or as a separate income line item. Expanded disclosures about the nature, terms, and conditions of grants are required. This ASU is effective for annual reporting periods beginning after December 15, 2028 and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statements and related disclosures.

| Fair Value Measurements | Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The Company uses the following hierarchy to classify inputs used in measuring fair value: Level 1Quoted prices in active markets for identical assets or liabilities. Level 2Observable inputs other than Level 1 Level 3Unobservable inputs The Company measures fair value using the market approach based on observable market data for identical or comparable instruments. The following tables summarize the Company’s financial assets (cash equivalents and marketable securities) at fair value:
There were no liabilities measured at fair value on a recurring and non-recurring basis as of March 31, 2026 and December 31, 2025. The money market funds are highly liquid and primarily invest in short-term fixed income securities issued by the U.S. government and U.S. government agencies. The fixed income mutual fund is a short-term investment which primarily invests in debt securities issued by the U.S. government and U.S. government agencies and corporate bonds and notes. Interest income from short-term investment is recorded in interest income. During the three months ended March 31, 2026 and 2025, the Company recognized $0.2 million and $0.1 million in unrealized losses from its short-term investment, respectively. The Company’s short-term investment had a cumulative unrealized net gain of $0.0 million and $0.2 million as of March 31, 2026 and December 31, 2025, respectively.

| Commitments and Contingencies Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Commitments and Contingencies | Commitments and Contingencies Facility Lease The Company leases combined office and manufacturing facilities in Mountain View, California under a non‑cancelable operating lease originally entered into in 2011 and amended most recently in 2022 to extend the term through June 2030. The lease includes an option to extend for an additional five‑year period through June 30, 2035. The renewal terms have not been included in the lease term used to calculate the right-of-use assets and lease liability as it is not reasonably certain that the Company will exercise the option. In connection with the lease, the Company maintains a letter of credit of $0.2 million in lieu of a security deposit. The terms of the facility lease provide for rental payments on a graduated scale; however, rent expense is recognized on a straight-line basis over the lease term. The maturities of operating lease liabilities are as follows:
Operating lease cost was $0.7 million for the each of the three months ended March 31, 2026 and 2025. As of March 31, 2026, the remaining term for the operating lease in Mountain View, California was 4.25 years, and the discount rate used to measure the lease liability for such operating lease upon recognition was 8.5%. During the three months ended March 31, 2026 and 2025, cash paid for amounts included in operating lease liabilities of $0.8 million and $0.7 million, respectively, was included in cash flows from operating activities on the condensed statements of cash flows. Distribution Agreement In August 2022, the Company entered into an exclusive distribution agreement, or the Distribution Agreement, with DIXI Medical USA Corp, or DIXI Medical, for its stereo electroencephalography product line, with an initial term through September 30, 2025. The Distribution Agreement required annual purchase commitments, which increased by 10% each year during the term. The Company satisfied these purchase commitment. The Distribution Agreement provided for automatic one-year renewals unless either party gave at least 180 days notice of non-renewal. In March 2025, the Company provided notice of its intent not to renew and the Distribution Agreement terminated on September 30, 2025. Following expiration, the Company was permitted to sell remaining inventory during a wind-down period, after which DIXI Medical was required to buy back, at cost, any DIXI product inventory with at least six months remaining shelf life held by the Company. In December 2025, the Company and DIXI Medical amended the Distribution Agreement to end the wind-down period and cease commercial partnership activities on December 31, 2025. The Company has substantially completed the return of remaining inventory and had $0.4 million DIXI inventory as of March 31, 2026. As discussed in Note 12, the Company expects to complete the return of all remaining DIXI inventory to DIXI Medical and cease all commercial partnership activities related to its Distribution Agreement with DIXI Medical by June 30, 2026. Indemnifications In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and indemnification provisions. The Company’s exposure under these arrangements is unknown, as it involves potential future claims. The Company also indemnifies its directors and officers, subject to certain limits, as permitted under Delaware law and its governing documents. These obligations extend through the duration of any related proceedings, and the maximum potential payments are not estimable. The Company believes that the fair value of such obligations is minimal and has not recognized any liabilities as of March 31, 2026 and December 31, 2025. Contingencies From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities. The Company records a liability for contingent obligations when a loss is probable and reasonably estimable. No accrual was required as of March 31, 2026 and December 31, 2025. Legal Proceedings The Company is not involved in any material legal proceedings. From time to time, the Company may be involved in litigation arising in the ordinary course of business. The Company regularly evaluates current information and records accruals as appropriate. Legal costs are expensed as incurred. No material accruals were recorded as of March 31, 2026 and December 31, 2025.

| Debt | Debt CRG Term Loan In September 2020, the Company entered into a Term Loan Agreement with CRG Partners IV L.P. and its affiliates, or the CRG Term Loan, and borrowed $50.0 million. The CRG Term Loan initially bore interest at a rate of 12.5% per year and was interest-only through maturity on September 30, 2025. In February 2023, the CRG Term Loan was amended which increased the annual interest rate to 13.5% effective March 1, 2023. In May 2024, the maturity date was extended to September 30, 2026. Interest was payable quarterly at the end of each calendar quarter. The CRG Term Loan was collateralized by substantially all of the Company’s assets and included customary covenants and default provisions. In June 2025, the Company repaid the CRG Term Loan in full using the proceeds from MidCap Term Loan (as defined below). Total repayment amounted to $61.9 million, including principal of $56.0 million, interest of $1.4 million and backend fee of $4.5 million, which was reduced from 10% to 8% upon repayment. The repayment was accounted for as a debt extinguishment and the Company recorded a loss on extinguishment of $0.5 million included in other income (expense), net in the statements of operations and comprehensive loss. During the three months ended March 31, 2025, the Company recorded interest expense and interest expense related to debt discount and debt issuance costs of the CRG Term Loan of $2.2 million and less than $0.1 million, respectively. MidCap Term Loan In June 2025, the Company entered into a credit, security and guaranty agreement (see Note 1), or MidCap Credit Agreement, with MidCap Funding IV Trust, as agent, MidCap Financial Trust, as term loan servicer and the financial institutions and other entities from time to time party thereto, or the Lenders. The MidCap Credit Agreement provides for a first lien senior secured credit facility consisting of (i) a $60.0 million term loan facility, or MidCap Term Loan, which was funded at closing of the MidCap Credit Agreement, and (ii) a revolving credit facility in an aggregate principal amount not to exceed $15.0 million, or the Revolver, and together with the MidCap Term Loan, the Loans. The Loans mature on June 4, 2030 with principal due at maturity. The MidCap Term Loan bears interest at an annual rate of the 30-day forward-looking term Secured Overnight Financing Rate, or SOFR, plus 5.5%, subject to a 2.0% SOFR floor. Borrowings under the Revolver will accrue interest at an annual rate of the 30-day forward-looking term SOFR plus 3.75%, subject to a 2.0% SOFR floor. Following the initial borrowing of the Revolver, the Company will pay an unused line fee equal to 0.25% per annum of the average unused portion of the Revolver. Interest and unused line fee, if any, are payable monthly in arrears. The Company may repay the Loans, in whole or in part, at any time, subject to a prepayment premium of 3.0%, 2.0%, and 1.0% in the first, second and third years, respectively, and 0% thereafter. In addition, the MidCap Term Loan is subject to a 2% exit fee upon repayment. In addition, the Company shall pay an annual administrative fee, payable in advance, equal to 0.25% of the aggregate outstanding principal of the MidCap Term Loan. The Loans are collateralized by substantially all of the Company’s assets and subject to customary covenants and default provisions (see Note 1 for its financial covenants). The Company incurred $1.5 million of debt issuance costs, recorded as a discount on the MidCap Term Loan and amortized over the life of the loan using the effective interest method. Interest expense on the MidCap Term Loan was $1.5 million for the three months ended March 31, 2026, including interest expense related to debt discount and debt issuance costs of the MidCap Term Loan of $0.1 million. The Revolver has not been drawn upon as of March 31, 2026. The following table sets forth the Company’s future minimum payments for the MidCap Term Loan as of March 31, 2026. Estimated future interest payments are calculated using the effective interest rate of 10.8% at March 31, 2026.

| Income Tax Disclosure [Abstract] | |

| Subsequent Events | Subsequent Events As noted in Note 5, the Company and DIXI Medical amended the Distribution Agreement to end the wind-down period and cease commercial partnership activities on December 31, 2025. The Company has substantially completed the return of remaining inventory and had $0.4 million DIXI inventory as of March 31, 2026. During the period from April 1, 2026 to May 12, 2026, the Company returned $0.1 million DIXI inventory. As of May 12, 2026, the Company holds $0.3 million DIXI inventory, which it expects to return by June 30, 2026. Based on the facts and circumstances, management believes that the termination of its Distribution Agreement with DIXI Medical represents a strategic shift that is expected to have a major effect on the Company’s operations and financial results. The Company has evaluated the termination of the Distribution Agreement under the guidance in ASC 205-20 and expects that upon return of the remaining $0.3 million DIXI inventory, the criteria for presentation as discontinued operations will be met. Accordingly, the Company expects to present the operating results of the Distribution Agreement with DIXI Medical as discontinued operations in its condensed statements of operations and comprehensive loss in future periods, which may begin in the quarter ending June 30, 2026 and the applicable comparable periods presented. The following information presents selected historical operating results of the Distribution Agreement with DIXI Medical for informational purposes only and does not represent discontinued operations presentation for the periods presented.

Summary of Significant Accounting Policies (Policies) |
3 Months Ended |
|---|---|
Mar. 31, 2026 | |
| Accounting Policies [Abstract] | |
| Basis of Presentation and Unaudited Interim Financial Information | Basis of Presentation The unaudited interim condensed financial statements have been prepared in conformity with generally accepted accounting principles in the United States, or GAAP. Unaudited Interim Financial Information The condensed balance sheet as of December 31, 2025 was derived from the Company’s audited financial statements, but does not include all disclosures required by GAAP. The accompanying unaudited condensed financial statements as of March 31, 2026 and for the three months ended March 31, 2026 and 2025, have been prepared by the Company, pursuant to the rules and regulations of the SEC for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2025 and notes thereto, which are included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC on March 3, 2026. In the opinion of management, all normal recurring adjustments necessary for a fair presentation have been included. The results for the three months ended March 31, 2026 are not necessarily indicative of the results for the year ending December 31, 2026.
|
| Use of Estimates | Use of Estimates The preparation of unaudited interim condensed financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts and disclosures. The Company uses significant judgments when making estimates related to the provision for excess and obsolete inventories. Actual results may ultimately materially differ from these estimates and assumptions.
|
| Concentration of Credit Risk, and Other Risks and Uncertainties | Concentration of Credit Risk, and Other Risks and Uncertainties Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents, short-term investments and accounts receivable to the extent of the amounts recorded on the balance sheets. The Company’s accounts receivable, with the exception of $0.1 million, are due from a variety of health care organizations in the United States. For the three months ended March 31, 2026 and 2025, there were no customers that represented 10% or more of revenue. As of March 31, 2026 and December 31, 2025, no customer represented 10% or more of the Company’s accounts receivable.
|
| Government Programs | Government Programs The Company continues to receive funding under its National Institutes of Health, or NIH, grant and recognizes funding as a reduction in research and development expenses in an amount equal to the qualifying expenses incurred in each period up to the amount awarded by the NIH. The Company received $0.2 million and $0.1 million in funding during the three months ended March 31, 2026 and 2025, respectively. Qualifying expenses incurred by the Company in advance of funding by the NIH are recorded within prepaid expenses and other current assets on the balance sheets. As of March 31, 2026, the Company recorded prepaid expenses and other current assets of less than $0.1 million related to the fifth year of funding.

| Recent Accounting Pronouncements Adopted and Not Yet Adopted | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In July 2025, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, No. 2025-05, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, providing a practical expedient to measure credit losses on current accounts receivable and current contract assets under Accounting Standards Codification 606, Revenue from Contracts with Customers. The practical expedient assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This ASU is effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods and should be applied prospectively. The Company adopted this ASU effective January 1, 2026. The adoption of this ASU did not have an impact on the Company’s financial statements and related disclosures. Recent Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosure (Subtopic 220-40): Clarifying the Effective Date. ASU 2024-03 is intended to provide more detailed information about specified categories of expenses (including employee compensation, depreciation, and amortization) included in certain expense captions presented on the face of the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted, and may be applied either prospectively to financial statements issued for reporting periods after its effective date or retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact this standard will have on its financial statement disclosures. In December 2025, the FASB issued ASU No. 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities, providing authoritative guidance on the recognition, measurement, presentation, and disclosure of government grants received by business entities. The standard introduces a framework for determining when grants should be recognized, distinguishing between asset-related and income-related grants, and allows entities to present grants either as a reduction of related expenses or as a separate income line item. Expanded disclosures about the nature, terms, and conditions of grants are required. This ASU is effective for annual reporting periods beginning after December 15, 2028 and interim reporting periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact this guidance will have on its financial statements and related disclosures.
