AI agents need security layers — Runlayer just proved the market agrees.

Runlayer launched from stealth with $11M seed from Keith Rabois (Khosla) and Felicis to secure AI agents using Model Context Protocol.

• $11M seed, 8 unicorn customers in 4 months
• $3M revenue in first year
• MCP protocol creator joined as advisor

Founder playbook:
• Sold AI company Vowel to Zapier (2024)
• Became Zapier's AI director, built early MCP servers
• Spotted security gaps in rapid MCP adoption
• Left with 2 co-founders, recruited protocol creator
• Signed 8 unicorns while in stealth

Takeaway: Infrastructure gaps in fast-moving tech = opportunity. Move fast when you spot them.
