Kai, a cybersecurity startup developing an agentic AI platform designed to autonomously defend enterprises from digital threats, has emerged from stealth with $125m.
The company announced it has raised $125m in funding, led by Evolution Equity Partners, with participation from N47 and several strategic investors.
The investment marks the company’s public debut and underscores growing investor interest in AI-driven cybersecurity solutions capable of addressing increasingly sophisticated cyber threats.
Kai has developed what it describes as the first agentic AI cybersecurity platform capable of autonomously reasoning, acting and adapting at machine speed. The platform is designed to transform the way security teams operate by replacing fragmented tools and manual processes with intelligent AI agents that perform security tasks continuously and at scale.
The technology is built to operate across multiple areas of cybersecurity, including threat intelligence, exposure management, detection and response. By unifying these functions into a single AI-powered pipeline, the platform aims to remove traditional silos and eliminate the bottlenecks created by human-led workflows.
The newly secured funding will be used to expand the company’s go-to-market activities, strengthen its AI research capabilities and scale its platform to support increasing global demand. Kai said the investment will help it accelerate product development while growing its customer base across key industries.
Although still relatively new, the company has already reported strong early traction. Within just 10 months of writing its first line of code, Kai says it has signed multiple enterprise customers and generated seven-figure bookings, alongside building a growing sales pipeline. The platform is already being adopted across sectors including energy, pharmaceuticals, automotive and hospitality.
Kai has also participated in the Chevron Technology Ventures Catalyst Program, which focuses on advancing technologies capable of improving operations across Chevron’s business. The company said meeting the programme’s milestones validated the capabilities of its agentic platform in complex operational environments.
The firm was founded by industry veterans with experience building major cybersecurity companies. CEO Galina Antova previously co-founded Claroty, an industrial cybersecurity provider focused on protecting cyber-physical systems. CTO Dr. Damiano Bolzoni co-founded SecurityMatters, an operational technology cybersecurity firm that was later acquired by Forescout Technologies.
Kai CEO Galina Antova said, “Cybersecurity is quickly becoming a contest between AI systems. The decisive factor is which side has richer data and can act at machine speed with human expert accuracy. We’ve created a unified, agentic cybersecurity platform from the ground up. Kai replaces fragmentation with intelligent, autonomous agents that execute security work end-to-end: across multiple use cases, and we’re just getting started.”
Evolution Equity Partners founder and managing partner Richard Seewald said, “AI has ushered in a new era for cybersecurity, disrupting traditional defense while enabling new, automated attacks humans alone can’t match. Kai’s approach was designed to close that gap by letting agentic AI prioritize action and execute response. That shift is why we backed Kai, and why enterprises are moving quickly to adopt it.”
Kai CTO Dr. Damiano Bolzoni said, “Attackers don’t think in categories. Defense shouldn’t either. Kai allows enterprises to eliminate silos, transform entire security functions, and reduce risk faster than was ever possible with human-led workflows.”
