Depthfirst

depthfirst is an applied AI lab that develops security solutions designed to address vulnerabilities in the AI era. The company has built what it calls General Security Intelligence, which analyzes code and business logic context to identify security vulnerabilities in software systems. The company's platform integrates with GitHub repositories to scan for critical vulnerabilities. Their approach uses AI-native defense mechanisms to counter attackers who are leveraging AI to discover and exploit vulnerabilities at increased speed and scale. The founding team includes members with backgrounds from DeepMind, Google, Databricks, and Faire. The founders bring experience from building and securing large-scale software systems across startups, hyperscalers, and research labs. One co-founder previously worked at wholesale marketplace Faire and led security and fraud prevention at Cash App, while also conducting postdoctoral security research at UC Berkeley. Another founder built developer and security products at AWS and later joined Databricks as an early leader, building infrastructure and enterprise platform security. The third founder served as a Research Engineering Lead at Google DeepMind, working on reinforcement learning for projects including Gemini and AlphaDev. The company targets organizations that need to secure software systems against AI-powered threats, offering vulnerability detection capabilities that understand both code structure and business logic.
