For 150 years, people have answered it by hand. Clark is changing that.\nWe build AI that doesn’t just assist auditors. It does the audit work itself. More than 35 CPA firms already use Clark to run audit fieldwork faster and at equal or better quality. Audit is where we start. Our mission is to build the trust infrastructure layer for the AI economy, and we’re only getting started.\nWe’re a small, hard-working team backed by top investors.
