100-word summary
Cybersecurity startup Kai just raised $125 million in combined seed and Series A funding led by Evolution Equity Partners. The company is betting that defending against AI-powered attacks requires AI defenses that respond faster than humans can type. Kai hit seven-figure bookings in its first 10 months, selling into energy, pharma, automotive, and hospitality. Its acceptance into Chevron's tech program signals where the real anxiety lives: critical infrastructure operators worried about nation-state hackers who now have AI too. The pitch is simple: if attackers are automating at machine speed, your security team can't afford to wait for Monday's incident review meeting.
