AIUC Closes $40 Million Series A Round

Global Insurance Desk: Artificial Intelligence Underwriting Company, better known as AIUC, has closed a $40 million Series A funding round. Ribbit Capital led the investment, with First Harmonic joining in. The raise brings the San Francisco startup’s total capital to about $55 million after an earlier $15 million seed led by NFDG.

The company is building what it calls confidence infrastructure for artificial intelligence. That means creating standards, running independent audits, and tying insurance coverage to the results so businesses feel safer putting AI agents to work. Its core offering, called AIUC-1, functions a bit like the familiar SOC 2 certification but is tailored for AI systems. Agents are put through thousands of tests covering jailbreaks, hallucinations, data leaks, and unsafe tool use. The process produces detailed reports, and successful systems can unlock liability coverage that reaches tens of millions of dollars per policy.

Co-founders Rune Kvist and Rajiv Dattani bring relevant backgrounds to the effort. Kvist was Anthropic’s first product hire. Dattani previously served as COO of the AI safety group METR and worked as a partner in McKinsey’s insurance practice. In explaining the need for their approach, Dattani has pointed to the historical example of Underwriters Laboratories, which insurers supported to test electrical products after fires became a widespread problem. The pair argues AI now requires a similar combination of rigorous testing, clear standards, and financial protection.

Early customers include Cursor, Lovable, Harvey, and ElevenLabs. The new capital will help AIUC expand its testing work from individual agents to the frontier models those agents rely on, and scale the insurance side of the business. The company announced the round on September 15, 2026, according to its official statement.

As enterprises move beyond pilot projects, the practical risks of autonomous systems have become a bigger barrier than raw technical capability. AIUC is betting that independent verification linked to real insurance will clear that path. The funding arrives at a moment when more carriers and technology firms are looking for ways to manage the liability that comes with deploying AI at scale.
