Cybersecurity startup WhiteMatter on Tuesday announced raising $20 million in a Series A funding round that brings the total raised by the company to $24 million.
The investment round was led by Blumberg Capital, with additional support from previous investors Crew Capital and Sprout & Oak.
Founded in 2024 and previously known as QuilrAI, WhiteMatter has built a platform that helps organizations secure and govern every AI agent running in their environments.
According to WhiteMatter, enterprises can run every AI agent through its platform and 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, scaling if agents multiply autonomously, to ensure continuous policy-driven control.
The cybersecurity startup will use the new investment to accelerate research and development and expand its go-to-market organization. It will also build its executive team.
“Despite all the discussion about pausing AI development, enterprises are doing the opposite. AI technology is too powerful, the opportunity is too significant, and the competitive pressure is too real to put it back in the box,” said WhiteMatter founder and CEO Vidit Arora.
“Companies that slow down AI adoption risk being overtaken by competitors that move fast, stay secure, and scale AI with confidence, which is exactly why we built WhiteMatter,” Arora added.
WhiteMatter has headquarters in San Francisco and Austin.
