By Amit Chowdhry ● Jan 14, 2026
depthfirst, an applied AI lab focused on software security, has raised a $40 million Series A funding round as it positions its “General Security Intelligence” platform as a response to a fast-changing threat landscape shaped by AI-generated code and increasingly automated attacks. The round was led by Accel and included participation from Alt Capital, BoxGroup, Liquid 2 Ventures, Mantis VC and SV Angel, alongside angel investors Jeff Dean, Kirsten Green, Colin Evans, Logan Kilpatrick and Julian Schrittwieser, the company said.
