Subsequent Events [Abstract]
Subsequent Events	Note 18 — Subsequent Events On April 2, 2026, the Company’s board of directors approved a reverse stock split of its Class A common stock and Class B common stock at a ratio of 1-for-10 (the “Reverse Stock Split”). The Reverse Stock Split became effective at 4:00 p.m. Eastern Time on April 6, 2026, and the Company’s Class A common stock began trading on a post-split adjusted basis on April 7, 2026. The number of authorized shares and par value per share were not adjusted as a result of the Reverse Stock Split. All references to shares, options to purchase common stock, share amounts, per share amounts, and related information contained in the condensed consolidated financial statements have been retrospectively adjusted to reflect the effect of the Reverse Stock Split for all periods presented. The shares of common stock underlying outstanding stock options and other equity instruments, other than outstanding warrants, were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased in accordance with the terms of the agreements governing such securities. The number of warrants outstanding was not reduced as a result of the Reverse Stock Split. Rather, of the applicable warrant agreements, the number of shares of common stock issuable upon exercise of each outstanding warrant was proportionately reduced such that each warrant is exercisable for 1/10th of one share of common stock following the Reverse Stock Split, and the applicable exercise prices were proportionately increased, as applicable. Accordingly, the number of warrants outstanding has not been retrospectively adjusted or recast in the condensed consolidated financial statements. No fractional shares were issued in connection with the Reverse Stock Split, and cash was paid in lieu of fractional shares. On May 13, 2026, the Company entered into a First Amendment to the Securities Purchase Agreement and Senior Secured Convertible Note (the “First Amendment”) with Leviston Resources, LLC (“Leviston”), amending the Senior Secured Convertible Note originally issued on March 31, 2026 (the “Original Note”). Pursuant to the First Amendment, Leviston advanced an additional $833 to the Company, increasing the total funded amount under the Original Note to $3,333. The First Amendment increased the aggregate principal amount of the Original Note, inclusive of a 16.667% original issue discount, from $3,000 to $4,000. Interest on the incremental $1,000 of principal created by the First Amendment commenced accruing on May 13, 2026; interest on the original $3,000 principal continues to accrue in accordance with the terms of the Original Note as in effect immediately prior to May 13, 2026. The Company intends to use the proceeds for working capital and general corporate purposes. On May 13, 2026, the Company entered into an Investor Rights Agreement (the “IRA”) with Leviston, in connection with the Senior Secured Convertible Note originally entered into on March 31, 2026 and amended pursuant to the First Amendment described above. Pursuant to the IRA, the Company granted Leviston the right, but not the obligation, to purchase one or more additional senior secured convertible notes (each, an “Additional Note”) from the Company during the seven-month period commencing May 13, 2026 and ending December 13, 2026, in an aggregate principal amount not to exceed $4,000, with a corresponding maximum aggregate cash subscription amount of approximately $3,333, reflecting the same 16.667% original issue discount as the Original Note. Each Additional Note will be issued in minimum tranches of $300 of principal, will bear interest at 10% per annum (18% upon an event of default), will mature four months from its respective issuance date, and will be convertible into shares of the Company’s Class A Common Stock at a price equal to the lesser of (i) the closing price of the Common Stock on the applicable issuance date and (ii) 85% of the lowest 8-day volume-weighted average price immediately prior to and including the date of the applicable conversion notice. Any Additional Notes issued under the IRA will constitute senior secured indebtedness of the Company ranking pari passu with, and secured by the same collateral as, the Original Note. The Company intends to use any proceeds from exercises of the Investment Right for working capital and general corporate purposes. On May 18, 2026, the Company satisfied in full the entire $4,000 of outstanding principal under the Original Note, together with all accrued interest thereon, through the conversion of such amounts into an aggregate of 2,500,000 shares of Common Stock. Upon such full satisfaction, the Original Note, the Securities Purchase Agreement, dated March 31, 2026, between the Company and Leviston (as amended by the First Amendment), and the Registration Rights Agreement, dated March 31, 2026, between the Company and Leviston, terminated in accordance with their terms. On May 19, 2026, the Company entered into a Securities Purchase Agreement (the “Kips Purchase Agreement”) with Kips Bay Select, LP (“Kips”), pursuant to which the Company agreed to sell to Kips (i) 2,000 shares of Series A 10% Convertible Preferred Stock (the “Preferred Shares”) for aggregate gross proceeds of $2,400, and (ii) a Preferred Stock Purchase Warrant (the “Warrant”) to purchase up to an additional 6,000 shares of Series A 10% Convertible Preferred Stock at an exercise price of $1,000 per share. Kips funded $2,000, reflecting an original issue discount of $400, and $25 was withheld for legal fees, resulting in net proceeds to the Company of $1,975. Dividends are payable in cash, or at the Company’s option, Preferred Shares. The Preferred Shares and any shares issued upon exercise of the Warrant are convertible into shares of our Class A Common Stock in accordance with the terms of the Certificate of Designation of Preferences, Rights and Limitations of Series A 10% Convertible Preferred Stock (the “COD”). In connection with the transaction, on May 19, 2026, we also entered into a Registration Rights Agreement with Kips (the “Registration Rights Agreement”) pursuant to which we agreed to register the resale of shares of Class A Common Stock issuable upon conversion of the Preferred Shares and upon exercise of the Warrant.
