WhiteMatter, a cybersecurity startup focused on AI agent governance, announced on Tuesday that it has raised $20 million in a Series A funding round. The investment brings the company’s total funding to $24 million.
The round was led by Blumberg Capital, with additional participation from existing investors Crew Capital and Sprout & Oak. Founded in 2024 and previously operating as QuilrAI, WhiteMatter has developed a platform that enables organizations to secure and govern every AI agent running in their environments.
According to the company, enterprises can route all AI agents through its platform to gain visibility into where agents are built and used across endpoints, cloud, SaaS, and code. The solution deploys and governs every agent, model, and MCP server, observes and secures each action, and optimizes traffic through a single gateway.
WhiteMatter can deploy a dedicated guardian agent for every agent running in the environment. These guardian agents scale automatically if AI agents multiply autonomously, ensuring continuous policy-driven control.
The company plans to use the new capital to accelerate research and development, expand its go-to-market organization, and build out its executive team.
“Despite all the discussion about pausing AI development, enterprises are doing the opposite,” said founder and CEO Vidit Arora. “AI technology is too powerful, the opportunity is too significant, and the competitive pressure is too real to put it back in the box.”
Arora added that companies slowing AI adoption risk being overtaken by competitors that move fast while staying secure. WhiteMatter maintains headquarters in San Francisco and Austin.
