Opsin Raises $21 Million Led by SYN Ventures and Race Capital to Secure and Govern AI Agents in the Workplace

Employees now build AI agents inside tools such as Microsoft Copilot, Claude and ChatGPT Enterprise, and security teams often cannot see what those agents can reach. Opsin, a San Jose company that sells security and governance software for AI agents, raised $21 million to fix that, as reported in Fortune's Term Sheet newsletter on October 16, 2026.

SYN Ventures and Race Capital led the round. Business Insider reported the round first, and the company plans to use the money to expand sales and engineering.

What the Product Does

Opsin's platform gives security teams central visibility and control over agents that employees create across different platforms. It helps identify agents with excessive access and detect behavior outside an agent's intended purpose. In effect, it treats each agent as something that needs permissions and monitoring, in the way a company manages the access of a new employee.

The Company's Own Research

Opsin says its analysis found that 93% of misaligned tools connected to agents had full, unrestricted access to the systems they interacted with, and that only one in 200 required human approval before taking action. These are the company's findings, not independent measurements, and they are the kind of statistic security vendors use to describe a market. Founders should read them as the case Opsin makes for its product and not as a verified industry figure.

The Company and Its History

James Pham is chief executive, and the cofounders are Jeremy Mailen and Oz Wasserman. Sources disagree on the earlier funding: one profile describes a $7 million seed round led by Race Capital in April 2025, while another dates a $7 million seed to June 2024, and I could not reconcile the two.

What This Means for Founders

The round shows investors expect a new security category to form around AI agents, just as earlier waves of cloud and mobile software created their own. Companies that sell into a security budget have a clear buyer, but they also face a crowded field and a buyer who wants proof that a product reduces risk.

If you are building security software for a new technology, show a specific incident your product prevents and how quickly a customer sees value. When you raise a Series A, expect each lead investor to ask how you will stay ahead of larger security vendors that can add similar features. Consider how much dilution a round of this size carries relative to the milestones it should fund.
