Kai Raises $125M in Funding to Scale Agentic AI Security Platform

Silicon Valley loves speed. Faster chips. Faster code. Faster exits. But in cybersecurity the bad guys have quietly been moving faster than everyone else. AI writes exploits while humans are still opening dashboards and arguing over which alert matters. That gap between machine speed offense and human speed defense is exactly where Kai decided to plant a flag.

Out of San Jose, Kai just stepped out of stealth with $125M in funding and a clear message. Security teams cannot win tomorrow’s fights with yesterday’s tooling. Congratulations to Co Founder and CEO Galina Antova and Co Founder and CTO Dr. Damiano Bolzoni for building something that looks less like another security product and more like a security engine built for the tempo of AI itself.

The round was led by Evolution Equity Partners with participation from N47. Evolution Equity Partners Founder and Managing Partner Richard Seewald knows the cybersecurity chessboard well, and backing Kai signals something important. Investors are betting that autonomous security systems will soon move from theory to necessity. Not someday. Now.

Kai calls its platform agentic AI. Translation in street terms. Software that does the security work instead of just reporting on it. The platform reasons through threats, runs threat intelligence, manages exposure, handles detection and response, profiles risk, discovers shadow IT and OT, distills threat data, and even helps with regulatory compliance. Think less alert fatigue and more automated security muscle moving at machine speed.

The founders know this territory cold. Galina Antova helped build Claroty into one of the most recognized names in industrial cybersecurity. Dr. Damiano Bolzoni co founded SecurityMatters before its acquisition by Forescout. When people who spent their careers protecting cyber physical systems decide the next step is autonomous defense, it is worth paying attention.

The market already is. Within roughly 10 months of building the platform, Kai reports 7-figure bookings and adoption across industries that cannot afford downtime or uncertainty. Energy. Pharmaceuticals. Automotive. Hospitality. Sectors where IT meets OT and where the blast radius of a breach is measured in factories, supply chains, and real world consequences.

There is a quiet elegance in the name Kai. In several cultures it signals change, movement, or the sea itself. That feels fitting. Cybersecurity has been a tide of alerts, dashboards, and fragmented tools for years. Kai seems intent on turning that tide into something more autonomous, more unified, and a lot harder for attackers to outrun.

When defense starts moving at machine speed, the entire security conversation changes. And if the early traction is any signal, the industry might already be catching the current.
