About Chestnut
FoundersSpencer Brown Repeat founder building the first AI mortgage lender. My last startup built a system of record for mortgage lending that powered 2% of US mortgages annually. During that time, I saw firsthand how inefficient traditional lenders are – and realized I should compete with them directly. I started coding at age 12, founded my first company at 16, and was an early engineer at six other seed- and A-stage startups.About ChestnutChestnut is the first AI mortgage lender.
