TLDR: Mount is building the AI insurance carrier, starting with liability coverage for deployed AI agents. As everyone moves AI Agents into production and gives them more responsibility, we help businesses insure and secure them. Whenever responsibility shifts from human operators to autonomous systems, so too does the liability that accompanies it. The systems also introduce new risks: agentic software failures, prompt injection attacks, autonomous workflow errors, data leaks, and more. Legacy insurance was not built for this. Existing policies are often silent, ambiguous, or exclude autonomous software, and traditional insurers lack the data and technical capability to assess deployed AI Systems. Our first product, the Mount AI Liability Policy, is built for mid-market and enterprise companies deploying autonomous AI agents in real business processes. We scan and red-team AI deployments, quantify operational risk, help fix vulnerabilities, and insure the residual risk with purpose-built AI liability coverage. Mount is best thought of as a highly automated version of today's commercial insurance carriers, which run on manual workflows, layers of intermediaries, and tens of thousands of employees. AI enables automation of underwriting, pricing, policy issuance, claims, fraud detection, customer support, and distribution. We believe that the best way to use this opportunity is to rebuild those processes from the ground up.
