WhiteMatter (formerly QuilrAI)

Record description

WhiteMatter, previously known as QuilrAI, is an enterprise AI-agent governance company. Its November 10, 2026 announcement describes a $20 million Series A led by Blumberg Capital, with participation from Crew Capital and Sprout & Oak. The proposed platform inventories AI agents, models, MCP connections and other integrations, reviews deployments against policy, and uses per-agent Guardian decisions to mediate actions through selected endpoint, gateway and runtime paths.

WhiteMatter attributes 2.25 million Guardians, 116 billion interactions, policy decisions in 2.24 milliseconds, throughput up to 7,800 actions per minute and zero duplicate executions in one million internal tests to its own deployment measurements. These are vendor-defined populations and test conditions, not independent estimates of prevented compromises, comprehensive mediation or exactly-once effects after partial network failures. The critical security distinction is between an inventoried agent, a policy verdict, an intercepted tool request and the actual effect accepted by a remote system. Available disclosures do not yet establish full coverage of direct subprocess calls, credentials outside gateways, revocation during queued work or recovery after external execution.
