7AI

7AI is the swarming architecture bet in the AI SOC lane, from the team with the heaviest pedigree in it. Founded in Boston in 2024 by Lior Div and Yonatan Striem-Amit, the co founders of Cybereason, the company launched from stealth in February 2025 with a $36 million seed and closed a $130 million Series A in December 2025 led by Index Ventures with Greylock, CRV, and Spark, reported as the largest cybersecurity Series A on record, for roughly $166 million raised in its first eighteen months. It was named to the Fortune 2026 Cyber 60.

Where rivals route an alert through a single investigating agent, 7AI deploys a swarm: more than sixty purpose built agents specialized across five domains, endpoint, identity, cloud, email, and network, working the same alert in parallel, an endpoint agent enriching device context while an identity agent checks user behavior. The platform covers the full lifecycle, ingesting and triaging alerts, enriching signals, investigating across systems, threat hunting, and driving response, and positions explicitly against playbook based SOAR: agents reason through alerts case by case, including novel threats, rather than executing pre written rules. A managed service, PLAID, layers 7AI's agents with human expertise for teams that want outcomes rather than software, and the platform sells via contact sales and AWS Marketplace.

Independent coverage calls 7AI one of the most experimental platforms in the category: the architecture is impressive, performs well in large EDR and cloud estates, and rewards innovation driven teams with engineering capacity to tune it, while teams wanting turnkey supervised triage may find simpler overlay analysts faster to trust. No pricing is published. The bet buyers are underwriting is that swarming domain specialists, from the team that built Cybereason, become the architecture the category converges on.
