7AI emerged from stealth in February, announcing a $36 million Seed round from Greylock Partners, Spark Capital, and CRV. The company was founded by Div, the longtime CEO of Cybereason, and Striem-Amit, the company’s former CTO; both hold the same roles at 7AI. The company develops AI agents capable of fully automating the entire cyber incident-response process. It is headquartered in Boston and operates an R&D center in Israel.

Cybereason, the founders’ previous company, was established in 2012 and became known for its XDR (Extended Detection and Response) platform, its threat-intelligence team, and its DFIR (Digital Forensics and Incident Response) capabilities. It quickly grew into one of Israel’s most promising cyber startups, raising hundreds of millions of dollars. In its peak fundraising round in July 2021, one of the largest cyber rounds in Israel, Cybereason was valued at approximately $3 billion, a valuation that dropped to about $300 million just one year later.

In 2022-2023, amid the shutdown of the IPO market, the company faced difficulties and conducted three significant rounds of layoffs between 2022 and 2024. Last month, Cybereason was acquired for an undisclosed amount by LevelBlue, the world’s largest managed security services provider (MSSP).

“With attackers harnessing the power of AI to unleash unprecedented levels of cyber assaults, the time has come to equip defenders with the same cutting-edge technology. Our mission is clear: to arm these defenders with AI, turning the tide in the cybersecurity battle,” Striem-Amit wrote on LinkedIn back in February.
