What is Clark?
Clark is a New York-based company, founded by Enes Witwit, that builds autonomous AI audit staff for CPA firms. It raised an $11M seed led by Touring Capital in November 2026, bringing total funding to $16M, and says more than 35 CPA firms use it.
Clark sells Clerks: AI employees assigned to audit engagements the way a firm would assign a staff auditor. A Clerk takes ownership of an area of the engagement, gathers documents from the client, performs tests, drafts workpapers and follows up on open requests, while licensed CPAs review the work and keep sign-off. The company's AI teammate is called Ava, and Clark also ships an Excel add-in for work that stays in spreadsheets.
The Clerks run on what Clark calls Material Intelligence: an agent harness, document processing and a multi-layer memory that carries context across an engagement. Clark connects to SharePoint, Box, Google Drive, QuickBooks, Slack, Microsoft Teams, Excel and email, and uses UI automation for client portals that have no API. It states SOC 1 Type 2, SOC 2 Type 2 and ISO 27001 coverage, supports HIPAA and GDPR obligations, and says customer data is never used to train models.
Clark's most unusual commitment is its Peer Review Guarantee: if Ava extracts a value incorrectly or misses something and that becomes a peer review finding, Clark says it will pay damages, capped under the customer agreement, and refund fees on that client. Overrides made by the firm's own team are not covered. Named customers include CliftonLarsonAllen, Aprio, Kreischer Miller, Sensiba, Novak Francella and Lilling & Company. Pricing is not published; firms book a demo.
