Funding and growth
WhiteMatter raised $20 million in a Series A round led by Blumberg Capital, with existing investors Crew Capital and Sprout & Oak also participating. The San Francisco-based company, formerly known as QuilrAI, said it will use the funding for research and development, go-to-market expansion and investment in its executive team.
The company says its platform is built to govern AI agents, models and interactions across enterprise environments, from development through deployment and operation. It describes the system as a way to set controls before an agent goes into production as well as monitor actions while it is running.
How the platform works
WhiteMatter says its Guardian architecture can assign a dedicated Guardian agent to each agent an enterprise deploys, enforcing policy on that agent’s actions. The company says the system can provision another Guardian when an agent multiplies, maintaining what it describes as continuous control.
The platform is intended to operate across endpoints and browsers, software-as-a-service applications, cloud environments and code, according to the company. WhiteMatter says it routes agent activity through a controlled gateway that can govern and deploy agents, models and MCP servers, while observing actions and managing agent traffic and spending.
In its description of the product’s performance, WhiteMatter says its decision architecture delivers policy decisions in 2.24 milliseconds and processes up to 7,800 actions per minute. The company also reports zero double executions in one million tests; those figures appear in its description of its own platform.
Customers and reported results
WhiteMatter says it has more than 2.25 million agents under management across customer environments and projects more than 5.5 million by year end. The company also reports that it has governed 116 billion AI interactions and saved customers more than 11 trillion tokens in the past nine months.
In 2026, the company says it tripled its customer base, grew revenue fivefold over the previous six months, and recorded approximately 200% net revenue retention with zero customer churn. It lists Sentara Health, Alter Domus, New American Funding and Concentrix among its customers, alongside Fortune 500 organizations.
Sentara Health Chief Information Security Officer Zishan Siddiqui said AI is becoming part of work across the health system’s 35,000-person workforce. He said WhiteMatter helps the organization see how AI is used, protect sensitive information at the point of use and guide employees toward appropriate tools and behaviors.
Alter Domus Chief Technology Officer Demetry Zilberg said the company has squads of industrialized agents in production and work that once took a quarter now takes a week. He said WhiteMatter checks agents before they go live and policy-checks tool calls through one gateway.
Company’s stated rationale
WhiteMatter argues that security systems designed for people and predictable software need controls suited to autonomous agents, which can access sensitive information, make decisions and move between systems. The company says many existing approaches detect risky behavior after it occurs, while its platform aims to apply controls during development and before deployment as well as at runtime.
Founder and Chief Executive Vidit Arora said enterprises are continuing to adopt AI amid competitive pressure. The company says the new funding will help it build what it describes as a security and operational layer for AI across enterprise deployments.
