Share
WhiteMatter, a cybersecurity startup, has raised $20 million in a Series A funding round to develop security and governance solutions for autonomous AI agents.
The investment brings the company’s total funding to $24 million. The round was led by Blumberg Capital, with additional support from existing investors Crew Capital and Sprout & Oak.
Formerly known as QuilrAI, WhiteMatter provides a platform designed to secure AI agents across an organisation’s infrastructure, including cloud, SaaS, endpoints, and code. The technology deploys a dedicated guardian agent for every individual AI agent in use, ensuring continuous, policy-driven control. The system is designed to scale automatically as agents multiply, monitoring actions and securing models and Model Context Protocol (MCP) servers through a single gateway.
The platform also offers visibility into where agents are built and deployed throughout the enterprise environment.
WhiteMatter founder and CEO Vidit Arora stated that the new investment will be used to accelerate research and development, expand the company’s go-to-market operations, and build out its executive team. Arora noted that despite discussions surrounding a pause in AI development, competitive pressures are driving enterprises to adopt the technology rapidly.
WhiteMatter is headquartered in San Francisco and Austin.
