7AI

7AI is a Boston-based cybersecurity company building an agentic security platform that deploys autonomous, reasoning-based AI agents to take over the repetitive investigation work that overwhelms security operations centers. Founded in 2024 by Cybereason co-founders Lior Div and Yonatan Striem-Amit, the company ingests alerts from a customer's existing security tools, triages and investigates them at machine speed, and surfaces only real threats with full context and recommended actions - cutting mean time to respond from hours to minutes and eliminating the bulk of false positives. In December 2025 it raised a $130M Series A, described as the largest cybersecurity Series A on record.
