AI security firm 7AI secures $130m Series A

7AI

AI security company 7AI, whose platform uses dynamic AI agents to automate security investigations and outcomes, has raised a major funding round of $130m to accelerate its growth.

The firm, which launched from stealth in February 2025, has quickly gained traction among large enterprises looking to reduce alert fatigue and speed up threat response times across their security operations.

The company has secured $130m in a Series A round led by Index Ventures, with new participation from Blackstone Innovations Investments. Greylock, CRV, Spark and all existing seed investors also backed the raise, marking the largest cybersecurity Series A in history. The injection takes 7AI’s total funding to $166m and comes less than a year after launch. Following the deal, Shardul Shah, partner at Index Ventures, will join the 7AI board of directors.

7AI develops agentic AI security technology designed to automatically investigate alerts, reduce false positives, and free security teams from repetitive tasks. In its first ten months in production, 7AI’s agents have processed more than 2.5m alerts and carried out over 650,000 investigations, cutting response times from hours to minutes. The company reports that customers have reduced false positives by as much as 95–99%, with enterprises saving between 30 minutes and 2.5 hours per investigation.

The funding will support expansion of 7AI’s AI security engineering and go-to-market teams as it grows through a channel-first strategy. The firm plans to increase deployment flexibility, strengthen enterprise support and extend its PLAID model (People-Led, AI-Driven), which offers a high-touch onboarding and guidance service from its expert team. The platform’s use cases include eliminating legacy security infrastructure, enhancing threat response, and helping senior security leaders apply AI transformation strategies across large organisations.

7AI counts customers across financial services, retail, technology and healthcare, including DXC Technology, which deployed what it describes as the world’s largest agentic security system in just eight weeks. Other enterprise use cases include helping security teams redeploy staff from level-one and level-two alert handling into strategic threat hunting roles.

7AI CEO Lior Div said, “There’s a fundamental flaw in how we’ve approached security operations for the past two decades. We keep adding more people and detection tools to handle exponentially increasing threats and alerts. The math just doesn’t work.”

“We’re at an agentic security inflection point that changes the equation entirely. Instead of security teams drowning in investigations that take hours, our AI agents complete them in minutes at a speed, accuracy, and consistency that’s difficult for humans and automation to match. What sets us apart is flexibility—customers choose how they want to engage with us based on their needs. We have the proof, and it’s in production right now: our AI agents do the investigation work so security teams can finally do human work: strategic threat hunting, proactive security and innovation through AI transformation.”
