Built to verify AI-generated code, the platform enables developers to pair natural language goals driven by AI agents with precise code assertions within local or CI environments. The company raised an $8M Seed round in November 2026 led co-equally by Credo Ventures and KAYA. Backed by Y Combinator's W26 batch, its angel roster includes high-profile founders from Vercel, Snowflake, Uber, and Cognition.
