Ravelin Raises $44M Series A for Offensive Agent Red-Teaming That Continuously Stress-Tests Customer-Facing AI Systems

  • AI Security
  • Red Teaming
  • Agent Eval

Red-teaming agents that probe customer-facing AI for prompt injection, tool abuse, and data exfiltration paths—continuous campaigns with fix tickets, not annual pen-test PDFs.

“You cannot govern agents you have never attacked. We industrialize the adversary for every release train.”

— Founder

“Agent security is dual-use by nature—Ravelin productizes the defensive side of that arms race.”

— Trae Stephens · Founders Fund
