Mindfort

co-founder and ceo @mindfort (YC X25) - building autonomous security agents

Mindfort deploys autonomous AI agents that continuously find, validate, and patch security vulnerabilities in web applications, operating as a 24/7 AI red team for engineering and security teams at startups and public companies. The launch marks MindFort's $3M+ seed announcement , which founder Brandon Veiseh says will fund infrastructure to meet growing demand and expand the team into new security verticals. It arrives as pressure mounts on companies to prepare defenses for AI-driven attacks, with quarterly manual pentests and noisy traditional scanners struggling to keep pace. Teams point Mindfort at a live web app and thousands of agents run in parallel to surface exploitable vulnerabilities, then ship automated pull requests to fix them. The platform can run continuously, on a schedule, or inside CI, and its API exposes the same agents for tasks like triaging bug reports, validating findings, and running targeted security reviews. This launch also introduces Hill Climb, a recursive learning system that lets agents consolidate memories across runs so they become more efficient at finding real exploits over time, which addresses the false-positive problem where traditional scanners generate 30-50% false positives that typically drown engineering teams in noise. Mindfort is a Y Combinator X25 company founded in 2025 by Akul Gupta and Brandon Veiseh , based in Los Angeles, with Sam Akhavan rounding out the founding team. Veiseh leads as CEO and Gupta as CTO, both with backgrounds spanning AI and cybersecurity. Soma Capital and Y Combinator are among the backers supporting the company's push to turn continuous, autonomous pentesting into a default part of the software delivery pipeline.
