| Debt | 4. DebtCustomers Bank Credit Facility In December 2022, the Company entered into a loan and security agreement with Signature Bank, which was subsequently succeeded by Customers Bank, (the “Customers Loan Agreement”). Under various amendments to the Customers Loan Agreement, the Company issued the lender a warrant that was exercisable for up to 58,420 shares of Series B convertible preferred stock at an exercise price of $6.93 per share (the “Series B Warrant”) and a warrant that was exercisable for up to 20,375 shares of Series C convertible preferred stock at an exercise price of $10.74 per share (“Series C Warrant”). The number of shares exercisable under the Series B Warrant and Series C Warrant were subject to certain revenue and debt draw milestones. In connection with the close of the Company's IPO on July 24, 2025, all of the outstanding shares of convertible preferred stock were converted into common stock. As a result, the warrants to purchase convertible preferred stock became exercisable into shares of common stock. Refer to Note 2 for additional information regarding the reclassification of certain warrants from liability classified to equity classified during the year ended December 31, 2025 as well as the exercise of the Series B Warrant and Series C Warrant during the three months ended March 31, 2026. On October 29, 2025, the Company amended the Customers Loan Agreement (the “Fifth Amendment”) to expand the credit facility to include (i) a term loan in the principal amount of up to $50.0 million (the “Term Loan”), $17.5 million of which is contingent upon the achievement of requisite revenue milestones, and (ii) a $10.0 million non-formula revolving line of credit (the “Non-Formula Revolving Line”), provided that the aggregate borrowings under the Term Loan and the Non-Formula Revolving Line may not exceed $50.0 million. The maturity date of the Term Loan was extended to October 15, 2030, with an interest-only period through October 15, 2027, followed by principal repayment over 36 months thereafter. Upon achievement of a certain revenue milestone, the interest-only period and repayment terms of the Term Loan may be extended through April 15, 2028 followed by principal repayment over 30 months, and upon achievement of an additional revenue milestone, may be further extended through October 15, 2028, followed by principal repayment over 24 months thereafter. The Non-Formula Revolving Line will mature on October 15, 2028. The applicable per annum interest rate did not change as a result of the Fifth Amendment and remains as the greater of (a) WSJ Prime Rate + 0.25% or (b) 5.25%, and resulted in a 7.00% interest rate as of March 31, 2026. On December 23, 2025, the Company amended the Customers Loan Agreement (the “Sixth Amendment”) to permit the Company to maintain certain limited deposit accounts outside of Customers Bank. No other terms of the Customers Loan Agreement were affected by the Sixth Amendment. The Fifth and Sixth Amendments were accounted for as debt modifications with no gain or loss recognized. The carrying value of amounts outstanding under the Customers Loan Agreement approximates its fair value as of March 31, 2026. The fair value of the Term Loan is classified as a Level 2 measurement as it is based on observable market inputs, including interest rates charged for similar financial instruments with comparable terms and maturities. As of March 31, 2026, $15.6 million of principal was outstanding under the Term Loan that will mature on October 15, 2030 and there were no borrowings outstanding under the Non-Formula Revolving Line. As of March 31, 2026, an aggregate $26.9 million remained available for borrowing under the Term Loan and the Non-Formula Revolving Line, net of amounts outstanding of $15.6 million. The Company was in compliance with all applicable Customers Loan Agreement covenants. Interest expense on the Customers Loan Agreement was $0.3 million and $0.4 million for the three months ended March 31, 2026 and 2025, respectively. Of these amounts, less than $0.1 million and $0.1 million were related to amortization of the debt discount and issuance costs for the three months ended March 31, 2026 and 2025, respectively. The effective interest rate was 7.60% as of March 31, 2026. The following table summarizes contractual principal payments as of March 31, 2026:
