Why We Invested in WhiteMatter and Building the Security Layer for the Agentic Enterprise

By Pramod Gosavi and Jared Katzen

WhiteMatter, formerly QuilrAI, secures and operationalizes the agentic enterprise across the entire agent lifecycle. Blumberg Capital is proud to lead the company’s $20M Series A, with participation from existing investors Crew Capital and Sprout & Oak. The funding will accelerate WhiteMatter’s product development and go-to-market expansion as enterprises move from AI experimentation to AI deployment—and confront a fundamental challenge: traditional enterprise security was not designed to govern autonomous agents.

This transition is accelerating faster than anticipated.

A year ago, AI security meant controlling which developers had access to GitHub Copilot. Today, boards and CEOs are mandating AI adoption across entire workforces, and the tools they’re deploying including browser-based copilots, coding agents, and autonomous workflow systems don’t fit neatly into traditional security categories. A single agentic interaction can touch identity, data, endpoint, network, and application surfaces simultaneously. As autonomous agents become more prevalent, enterprises need a new security layer built specifically for them.

The AI security market is projected to reach $15B by 2028, reflecting the growing demand for solutions that can secure and govern AI at scale. The security leaders we speak with aren’t looking for another point solution. They want an AI security platform.

The problem is architectural.

Traditional security was designed for human users and predictable software, while AI agents can behave unpredictably and operate at speeds that human security teams cannot manage manually. Many existing solutions monitor activity and identify risks after they occur. Enterprises need security that governs agents before runtime and enforces policies continuously as they operate.

WhiteMatter addresses this challenge with an agent-native platform that secures and operationalizes the agentic enterprise across the entire agent lifecycle.

Rather than addressing individual points of exposure, the platform provides governance, security and optimization across the environments where AI is built, deployed and operated, including browsers, endpoints, SaaS applications, cloud infrastructure and code. What differentiates WhiteMatter is its Guardian agent architecture. For every AI agent an enterprise deploys, WhiteMatter can provision a dedicated Guardian agent to enforce security and governance policies on its actions. As autonomous agents multiply, WhiteMatter scales its Guardian architecture alongside them. Its decision architecture delivers policy decisions in just 2.24 milliseconds, enabling real-time enforcement at machine speed. Combined with a unified gateway for managing agent interactions and spending, this approach enables enterprises to govern AI at a scale human security teams could not manage manually.

WhiteMatter has quickly scaled across enterprises spanning healthcare, financial services, telecom, and technology, including some of the most security-sensitive sectors in the market.

The company now has more than 2.25 million agents under management and has governed over 116 billion AI interactions. Revenue has grown fivefold in the past six months, with approximately 200% net revenue retention and zero customer churn. The pattern across these accounts is consistent: customers land on one use case and expand across surfaces as WhiteMatter’s platform proves out in production.

The credit for its commercial velocity goes directly to the founding team.

CEO Vidit Arora was part of the founding team at Securonix, where he helped scale the company from zero to $100+ million in revenue before its acquisition by Vista Equity in 2022. That experience gave him a firsthand understanding of the limitations of traditional security architectures and the opportunity to rethink them for autonomous AI.

Blumberg Capital has invested in cybersecurity for decades. We’ve seen how major shifts in enterprise technology create opportunities for new market leaders. As autonomous agents become integral to enterprise operations, security and governance will become foundational to how AI is deployed and scaled. WhiteMatter stands out for its agent-native architecture, comprehensive platform approach and demonstrated enterprise traction. Combined with Vidit’s experience building cybersecurity solutions at scale, the company is well positioned to help define this emerging category.

Congratulations to Vidit and the WhiteMatter team! We’re proud to support their vision of enabling enterprises to accelerate AI adoption without compromising security or control.
