Kai was founded on a simple and radical conviction: you cannot win a machine-speed war with human-speed defenses. Not with more tools. Not with more headcount. Not with AI bolted onto the same fragmented stack. The only real answer is to stop deploying tools and start deploying intelligence – an agentic layer that executes security work end-to-end, the way attackers already operate.
The Wall Street Journal reports that Kai recently raised $125 million in a combined seed and Series A round led by Evolution Equity Partners.
Galina Antova, Co-Founder and CEO at Kai, told Cybercrime Magazine that Fortune 500 companies have on average 80 to 120 security tools. “When attackers are coming and attacking organizations, they’re not stopping at the door to ask – excuse me, what Gartner category should I get through.”
While 89 percent of security leaders say they’re prepared for AI-driven attacks, most organizations still rely on manual vulnerability management and human intervention, according to Kai’s 2026 State of Autonomous Defense Report.
“The only chance that we have is machine-to-machine, AI agent to AI agent communication, and autonomously executing on that defense,” said Antova.
