Opsin, an AI security and governance startup, announced on October 15, 2026, that it has raised $21 million in a funding round led by SYN Ventures and Race Capital. The company helps organizations monitor where AI agents are active, what data they access, and flag risky behaviors.
As employees increasingly deploy autonomous AI agents from providers like OpenAI and Microsoft into corporate workflows, tracking their actual operations has become challenging. Opsin provides a comprehensive view of agent activities within an organization and offers continuous monitoring to identify potential risks.
The new capital will be used to expand Opsin's sales and engineering teams. CEO James Pham noted that security concerns were slowing down AI adoption, necessitating scalable solutions. Investor Glenn Chisholm highlighted that the growing use of AI products expands the attack surface, driving increased venture capital interest in cybersecurity.
