Equity comp at Zapata Quantum, Inc.
- Zapata Quantum completed a SPAC merger in March 2024 when Andretti Acquisition Corp. merged with Zapata Computing, Inc. and domesticated as a Delaware corporation. The company ceased operations in October 2024 due to debt obligations, filed for bankruptcy in 2025, and re-emerged as Zapata Quantum focused on quantum software after converting over $10 million of debt to equity. Pre-restructuring equity plans were substantially disrupted by the bankruptcy. As of year-end 2025, total unrecognized stock option compensation was approximately $1,849, indicating minimal active grants. The company has used stock options rather than RSUs as its primary equity vehicle both before and after restructuring.
- Vesting schedule: stock options vest monthly over four years with a one-year cliff on initial grants.
