AI Startup Claims Record $250K Bug Bounty

Grego AI launched today with a multi-agent system called Deep Invariant Analysis, designed to find critical software vulnerabilities that human auditors and automated tools miss. The system traces logic across multiple layers of code dependencies, deploys sandbox agents to explore different paths, and generates proof-of-concept exploits to confirm real flaws. The startup claims its AI discovered a vulnerability in an unnamed blockchain protocol that could have enabled a $27.7 million theft, earning a $250,000 bug bounty it calls the largest ever paid for an AI-found flaw. Co-founded by a top-ranked bug bounty hunter and a mathematics prodigy, Grego AI is backed by cyber•Fund and Vercel CEO Guillermo Rauch.
