AI-native liability insurance for deployed autonomous agents

Visit Website

Overview

Mount is a direct-to-consumer commercial insurance carrier founded in May 2026 and purpose-built to insure autonomous AI agents. The company targets mid-market and enterprise organizations running production AI deployments, covering direct financial loss from incidents such as unauthorized agent actions, erroneous outputs, data misuse, and prompt manipulation.

The carrier combines vulnerability scanning and red-teaming of deployed AI systems with insurance underwriting. Before binding coverage, Mount assesses agent behavior, delegated authority scope, and workflow exposure to quantify operational risk. Identified vulnerabilities receive automated remediation recommendations. Policies activate in 48 hours and are priced dynamically based on the ongoing risk assessment, replacing manual underwriting with real-time data from continuous agent monitoring.

Mount participated in Y Combinator's Spring 2026 batch and was co-founded by Fabian Amherd and John Bachmann. The company emerged to fill a specific market gap created when major carriers -- including AIG, Great American, and WR Berkley -- issued AI exclusion endorsements that took effect in January 2026, removing AI-related claims from their standard commercial policies.
