Grego AI
A security firm that uses AI to hunt for serious bugs in smart contracts and blockchain code — the kind of flaw that, left unfound, can lead to millions of dollars stolen.

Description
Smart contract code controls real money directly, with no bank to reverse a mistake — a single overlooked bug can mean an instant, irreversible multi-million-dollar loss. Traditional audit firms review code manually or with static-analysis tools that mostly pattern-match against known bug types. Grego AI instead uses what it calls Deep Invariant Analysis: it ingests an entire codebase, builds a model of how every module and dependency actually interacts, then launches autonomous AI sub-agents that each explore a different path through that model, spinning up sandboxes to write and test real proof-of-concept exploits rather than just flagging suspicious-looking patterns.
The company, founded by a top-30-ranked bug bounty hunter and a national math olympiad medalist, has raised $63M and holds the #1 spot on the Immunefi and Hackenproof leaderboards for AI security tools — including finding a vulnerability that could have led to a $27.7M loss on a major blockchain protocol. It offers no public self-serve pricing; engagements are scoped and quoted directly, with results guaranteed within the first 48 hours of starting.
💬 Our review
The short version: Grego AI's core claim — that it finds critical vulnerabilities other scanners and even major audit firms miss — is backed by concrete, checkable results (leaderboard rankings, a documented $27.7M near-miss, $63M in funding), which is unusually strong evidence in a security-tooling space full of vague marketing claims.
It competes with established smart-contract audit firms (Trail of Bits, OpenZeppelin, CertiK) and other emerging AI-driven scanners, but its specific pitch — autonomous agents building and testing real exploits against a modeled understanding of the code, rather than pattern-matching static analysis — is a genuinely different technical approach. With no public pricing, budgeting requires a direct conversation, which is standard for this category but still worth knowing going in; for a DeFi protocol or project handling meaningful value, the documented track record makes it worth that conversation.
