About Mount
Summary
Mount builds an AI-native insurance carrier for businesses deploying autonomous AI agents in production. Its first product, the Mount AI Liability Policy, targets mid-market and enterprise companies and covers eight risk categories including agentic software failures, harmful outputs, business interruption, and data incidents that legacy commercial policies either exclude or leave ambiguous. Mount scans and red-teams live AI deployments, quantifies operational risk, surfaces remediation steps, and then writes purpose-built liability coverage against the residual exposure.
Business model
Instant-activation insurance policies with dynamic, real-time pricing tied to each customer's scanned risk profile.
Go-to-market
Mid-market and enterprise teams deploying AI agents are the primary buyers; customers enter through a self-serve quote and free agent security test on the website, with coverage activated within 48 hours.

The AI Agent Insurance Carrier
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.
