Clark announced an $11M seed round on November 2, 2026, alongside the launch of Clerks, autonomous AI employees that perform audit work for CPA firms. Touring Capital led the round, with participation from returning investors Marathon Management Partners, Rerail, and Sofeon Ventures. Together with a $5M round Marathon Management Partners led in September 2025, Clark’s total funding reaches $16M.
Clark, formerly known as uiAgent, is headquartered in New York and builds AI for professional services firms, starting with audit and assurance. Enes Witwit is founder and CEO. The company’s stated mission is to make it possible to verify the economy in real time.
Each Clerk is assigned to an engagement the way a staff auditor would be. It works through audit areas by reviewing documents, performing tests, and preparing workpapers. When something is missing, it requests it from the client, tracks the response, and resumes the work when the information arrives, without being prompted again.
Clerks run on Material Intelligence, the AI operating system Clark built as their brain. It combines an agent harness, document processing, and a multi-layered memory system modeled on human memory, so a Clerk carries context forward the way an experienced auditor does. Routine updates are handled quietly, and anything that needs an auditor’s attention is escalated with evidence attached. Licensed CPAs make the professional judgments, review the work, and sign the opinion.
Clark says more than 35 CPA firms already use it on audits, including CliftonLarsonAllen, Aprio, Kreischer Miler, and Sensiba. The company also offers CPA firms a 100% accuracy guarantee and a peer review guarantee. Witwit said a promise of accuracy only means something when money is behind it.
Witwit argues that auditing today happens once a year, long after the decisions it was meant to inform. Clark says it is working toward continuous monitoring, where each finding states what it covers and when it was last checked. The company also points to government spending, citing a U.S. Government Accountability Office estimate that the federal government loses $233 billion to $521 billion a year to fraud.
Priya Saiprasad, co-founder and general partner at Touring Capital, called assurance a trust business. She said Clark’s Clerks carry engagements forward on their own, and that this could underpin a new operating model for assurance.
Clark will use the funding to expand its senior team across product, engineering, and sales. It also plans to bring Clerks to more firms and engagement types, help CPA firms extend audit services into government, and build toward fully autonomous audit employees. The customer count and guarantees are self-reported.
