depthfirst

depthfirst is a San Francisco applied AI lab building an AI-native security platform that detects, triages and remediates software vulnerabilities before attackers can exploit them. Its 'General Security Intelligence' uses custom AI agents and purpose-trained security models to read a company's code, business logic and infrastructure, surfacing more true-positive vulnerabilities while cutting false positives and delivering developer-ready fixes. Founded in 2024 by leaders from Databricks, Google DeepMind and Faire, the company raised $120M across Series A and B within a few months of leaving stealth.
