7AI Raises $130M Series A
7AI, a Boston-based cybersecurity startup specializing in autonomous AI agents for enterprise security, has raised $130 million in a Series A funding round. This financing brings the company's total funding to $166 million, following its initial launch from stealth in February 2025.
The round was led by Index Ventures, with participation from new investor Blackstone Innovations Investments, as well as existing seed investors Greylock, CRV, and Spark.
7AI plans to use the capital to expand its AI security engineering and go-to-market teams as the company continues to scale through its channel-first business model.
Founded in 2024 by CEO Lior Div, 7AI provides dynamic AI agents that autonomously investigate security alerts for large enterprises. The company's platform is designed to cut investigation times and eliminate false positives, allowing human security teams to focus on strategic threat hunting and proactive defense rather than manual triage.
