Chestnut

Chestnut is an AI-native operating system for insurance distribution, built for insurance carriers to manage the entire producer lifecycle. The Seattle-based, Andreessen Horowitz-backed company combines a purpose-built insurance data model with an API-first architecture and an agentic AI layer, providing producer onboarding automation (including NIPR integration), hierarchy configuration, incentive compensation management, debt management, performance tracking, and compensation intelligence. Chestnut positions its platform as a system of record that bridges carriers' operational needs to an agentic AI future, with an API-first, MCP-ready backend. Its public API and developer documentation are gated for carrier customers, so no public specification is available for the catalog at this time.

Chestnut is profiled on the APIs.io network. Tagged areas include Company, Insurance, InsurTech, Insurance Distribution, and Producer Management.

Chestnut’s developer surface includes support and 6 more developer resources.
