Palo Alto Networks in talks to buy AI agent security startup Clutch for $500 million

Palo Alto Networks is in talks to acquire Clutch Security, a startup that secures AI agents' access to company systems, for $500 million in cash plus milestone-based payouts, TechCrunch reports, citing a person familiar with the discussions. The three-year-old company was valued at $85 million when it raised a $20 million Series A in January 2025, led by Lightspeed and SignalFire, and is approaching $10 million in annual recurring revenue. That would price Clutch at about 50 times ARR. The premium reflects a market racing to protect software against attackers using AI; another startup, Upwind, recently turned down a Datadog offer that valued it at roughly 40 times ARR. If completed, it would be Palo Alto Networks' seventh acquisition this year. Neither company commented; The Information first reported the talks. Three years from founding to a half-billion-dollar exit is quick even by Silicon Valley standards.
