SAN FRANCISCO, Nov. 10, 2026 /PRNewswire/ -- AI agents are already operating across the enterprise, multiplying autonomously and acting at a speed traditional security was never built to govern. WhiteMatter, which quietly built its platform under the name QuilrAI, has raised $20M in Series A funding to secure and operationalize every agent, model, and AI interaction across the enterprise from pre-production governance and validation to securing every action at runtime.
Blumberg Capital led the round, with participation from existing investors Crew Capital and Sprout & Oak.
The problem is architectural: enterprise security was designed for humans and deterministic software that behaves predictably. AI introduces a different kind of actor – autonomous agents that can access sensitive information, create artifacts, make decisions, move across systems, and behave unpredictably, like spawning and influencing new agents. Securing that environment requires controls purpose-built for agents, but not just at runtime, rather where AI workflows are being built, deployed, and operating. Yet most of today's solutions still monitor from the outside in, detecting and escalating risky behavior after it happens rather than controlling it at the source before deployment.
"Despite all the discussion about pausing AI development, enterprises are doing the opposite," said Vidit Arora, Founder and CEO of WhiteMatter. "AI technology is too powerful, the opportunity is too significant, and the competitive pressure is too real to put it back in the box. 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."
Rather than slowing AI adoption, WhiteMatter is the platform enterprises run their AI agents through, present everywhere AI is used, built, and run: endpoint and browser, SaaS, cloud, and code. It governs and deploys every agent, model, and MCP server in the environment; secures and observes each action before and after it executes; and optimizes agent traffic as well as spend through one controlled gateway. Point solutions cover one layer. WhiteMatter covers the system.
For every agent an enterprise deploys, WhiteMatter can deploy a dedicated Guardian agent to enforce policy on every action it takes. If agents multiply autonomously, WhiteMatter scales with them, automatically provisioning a new Guardian for every new agent to ensure continuous, policy-driven control across the enterprise.
WhiteMatter is already deployed at companies including Sentara Health, Alter Domus, New American Funding, Concentrix, and many Fortune 500 organizations. In 2026, demand accelerated sharply: the company tripled its customer base, grew revenue fivefold over the past six months, and achieved approximately 200% net revenue retention with zero customer churn.
"At Sentara Health, our mission is to improve health every day, and technology is increasingly important to how we deliver on that mission. As an integrated health system with both care delivery and health plan services, we made the decision early to operationalize AI rather than simply pilot it. Today, across our 35,000-person workforce, AI is increasingly becoming part of how we work, deliver care and serve our patients, members, and communities," said Zishan Siddiqui, Chief Information Security Officer at Sentara Health. "WhiteMatter is helping us scale that adoption responsibly by providing greater visibility into how AI is being used, protecting sensitive information at the point of use, and guiding our workforce toward appropriate behaviors and tools in real time. We're not governing AI to slow innovation. We're creating the trust and guardrails that allow us to innovate responsibly, keep saying yes, and ultimately advance our mission of improving health every day."
"At Alter Domus, we scale practical AI with measured returns: squads of Industrialized Agents in production, and work that used to take a quarter now takes a week," said Demetry Zilberg, CTO of Alter Domus. "That pace is only responsible if governance keeps up. With WhiteMatter in our cyber defense stack, every agent is governed before it goes live, every tool call is policy-checked at one gateway, and the telemetry shows us where AI actually creates value. Security, adoption, and enterprise value aren't separate conversations here. They're one lifecycle, and we can see all of it."
Today, WhiteMatter has more than 2.25 million agents under management across customer environments, with over 5.5 million projected by year end. The company has governed 116 billion AI interactions and saved its customers over 11 trillion tokens in the past nine months alone.
QuilrAI, now WhiteMatter, grew out of Arora's experience building enterprise security. As a founding member of Securonix, he spent more than a decade helping build security products at scale. As AI shifted from a tool people use to agents capable of making autonomous decisions, Arora saw the traditional security model begin to break. He founded QuilrAI on the belief that companies would need to rethink enterprise control and infrastructure for a world built around agents, a thesis that has since grown into WhiteMatter's broader vision to help secure and operationalize the agentic enterprise.
"Every wave of enterprise computing eventually produced its own security layer, from the network to the cloud to identity," said Pramod Gosavi at Blumberg Capital. "Agents are the next wave and could soon outnumber employees inside enterprises, requiring a governance layer built natively for them. We backed WhiteMatter because its platform approach and Guardian agent model give enterprises the guardrails an autonomous workforce needs, at a scale no human security team could manage manually."
The funding will support research, development, and go-to-market expansion, alongside a significant investment in its executive leadership team. Together, the investments will help WhiteMatter build toward its vision of becoming the security and operational layer for AI wherever it is deployed, making every agent matter.

About WhiteMatter
WhiteMatter, formerly QuilrAI, is the first agent-native company built to secure and operationalize the agentic enterprise across the entire AI agent lifecycle. Foundation models are non-deterministic, so protecting agents only at runtime leaves every decision to the last millisecond and every alert to the security team. WhiteMatter treats AI security as a deployment problem first: every agent is assessed, governed against policy, and deployed from an approved blueprint before reaching production; while every action is governed before execution and every outcome is measured and validated.
Powered by its Guardian agent architecture, WhiteMatter brings continuous governance and control to the agents, models, tools, and integrations powering the enterprise. More than 2.25 million WhiteMatter Guardian agents run in customer environments today, governing more than 116 billion AI interactions. Its decision architecture delivers policy decisions in 2.24 milliseconds, processes up to 7,800 actions per minute, and has demonstrated zero double executions in one million tests.
WhiteMatter serves enterprises including Sentara Health, Alter Domus, New American Funding, Concentrix, and many other Fortune 500 organizations. It is currently backed by Blumberg Capital, Crew Capital, and Sprout & Oak. Headquartered in San Francisco and Austin, WhiteMatter enables enterprises to accelerate AI adoption without compromising security or control.
Govern. Secure. Optimize. Make Every Agent matter.
