Sequoia Capital Invests $30M in AI Security Startup Cymphony
Cymphony, a New York- and Tel Aviv-based startup focused on securing enterprise data from AI agents, has raised $30 million in funding led by Sequoia Capital. The Series A round values the company at over $100 million post-investment and follows an earlier undisclosed seed investment from Sequoia. As enterprises increasingly rely on AI tools that operate without traditional access controls, Cymphony aims to provide a unified view of both human and non-human identities within corporate systems. The startup’s platform includes a “workforce graph” combining identity, data, and activity signals to detect unauthorized access by AI agents or external collaborators. In one case, it identified 85,000 files exposed to AI tools at a U.S. public company and helped secure them before any breaches occurred. Sequoia’s investment was driven not only by Cymphony's product traction—seven figures in ARR within its first year of sales—but also the strong pedigree of co-founders Shy Dekel, Idan Berkovits, and Edi Gotlieb. The firm has been using Cymphony internally since early development stages.
