== History ==
According to ''[[Calcalist|Ctech]]'', Seven AI "was quietly founded in Boston at the end of 2023" and launched publicly in June 2024 with $36 million of seed funding led by [[Greylock Partners]], with [[CRV]] and [[Spark Capital]], both early backers of Cybereason. Div said that its valuation had already passed $100 million, although it had no product yet.<ref name="CtechSevenAI"/> ''SecurityWeek'' gives 2024 as the founding year and Boston as its base.<ref name="SecurityWeek7AI">Eduard Kovacs, [https://www.securityweek.com/7ai-raises-36-million-in-seed-funding-for-agentic-security-platform/ 7AI Launches With $36 Million in Seed Funding for Agentic Security Platform] ''SecurityWeek'', 6 February 2025, accessed 10 November 2026.</ref> Its founders had left [[Cybereason]], which ''Ctech'' said had seen hundreds of lay-offs and a 90% fall in value and had in effect been taken over by its main investor, [[SoftBank]].<ref name="CtechSevenAI"/>
