Clark Launches Autonomous AI Audit Clerks and Raises $11M Seed Round

What Clerks do

According to Clark, each Clerk is assigned to an audit engagement the way a staff auditor would be. It works through audit areas from start to finish: reviewing documents, performing tests and preparing workpapers.

When information is missing, the Clerk requests it from the client, tracks the response and resumes the work once the information arrives, without anyone prompting it again. Routine updates are handled quietly, and items that deserve an auditor's attention are escalated with the evidence attached.

Licensed CPAs remain in charge of the professional side. They make the professional judgments, review the work and sign the opinion. Clark says more than 35 CPA firms, including CliftonLarsonAllen, Aprio, Kreischer Miler and Sensiba, already use its software on their audits.

Clerks run on Material Intelligence, which Clark describes as the AI operating system it built to serve as their brain. It combines an agent harness, document processing and a multi-layered memory system modeled on human memory, so a Clerk can carry context forward the way an experienced auditor does.

Funding and guarantees

Touring Capital led the $11 million seed round. Returning investors Marathon Management Partners, Rerail and Sofeon Ventures also took part. Marathon Management Partners led an earlier $5 million round in September 2025, and the two rounds together make up the $16 million total. Clark was formerly known as uiAgent.

The company says it will use the money to expand its senior team across product, engineering and sales, bring Clerks to more firms and more types of engagements, and help CPA firms extend their audit services into government. It also plans to keep building toward fully autonomous audit employees.

Clark offers CPA firms a 100% accuracy guarantee and a peer review guarantee. "A promise of accuracy only means something when it has money behind it," said Enes Witwit, founder and CEO of Clark. "If AI is going to do the work, the company that built it should answer for it."

The case for continuous verification

Clark argues that the audit model has a timing problem. An audit opinion arrives as a snapshot of a year that has already ended, while AI has made invoices, records and even an executive's voice cheaper to fake. An answer that was right in March can be wrong by June.

The company points to the U.S. Government Accountability Office, which estimates that the federal government loses $233 billion to $521 billion a year to fraud. Clark notes that most audits of public money arrive after it has been spent. If verification becomes continuous and affordable, it says, CPA firms could offer new services that catch fraud and waste in government programs and businesses while a payment can still be stopped or recovered.

Clark is also working toward continuous monitoring between audits, with each finding stating what it covers and when it was last checked. The aim is for a firm to tell a client, a regulator or the public what is true now, not only what was true at year-end.

What it means for audit firms

For now, Clark says the Clerks work alongside auditors. The company measures success by how much time auditors no longer spend chasing documents, and how much more they spend on questions that need their judgment, rather than by the number of alerts its AI produces.

Priya Saiprasad, co-founder and general partner at Touring Capital, said AI creates an opportunity to "dramatically expand what CPA firms can accomplish without compromising that trust." She added that Clark's Clerks "carry an engagement forward on their own, coordinating with clients and acting as new information arrives."

Clark's stated direction is fully autonomous audit employees, though the release makes clear that licensed professionals retain responsibility for judgments, review and sign-off.
