7AI
A cybersecurity startup founded by Cybereason co-founders Lior Div (CEO) and Yonatan Striem-Amit (CTO) that builds specialized AI agents to take over essential 'non-human work' in security operations -- enriching signals, triaging alerts, searching for known threats, and correlating telemetry. 7AI raised a $130 million Series A led by Index Ventures with participation from Blackstone Innovations Investments, Greylock, CRV and Spark -- the largest Series A in cybersecurity history -- just ten months after launching from stealth, with its agents having processed over 2.5 million alerts and completed more than 650,000 investigations while cutting investigation times from hours to minutes and reducing false positives by up to 99%.
