About Chestnut

Chestnut is building the first AInative operating system for insurance distribution by transforming how the $1T+ insurance industry allocates its largest spend: sales and distribution.

Backed by a16z, we’re replacing legacy systems with a modern, flexible platform that helps carriers automate complex workflows, optimize every distribution dollar, and unlock new growth. We have major insurers under contract, and early adopters are expanding.

This is a generational platform shift. Recent advances in agentic AI make it possible to automate what was once manual and errorprone. We’ve spent years building the data model and context layer required to make this real, and now we’re scaling with urgency.

At Chestnut, we operate with the belief that small, highcontext teams working with bestinclass tools and colleagues can achieve outsized results. We embody what it means to be AIlean: chasing 10x productivity gains that allow us to scale impact beyond our headcount.

If you’re excited to modernize the infrastructure of one of America’s most essential industries, we’d love to meet you. Whether shaping core product experiences or laying the groundwork for intelligent automation, your work will accelerate a onceinageneration transformation.
