Tl;dr

Chestnut is hiring a Software Engineer to help Americans save billions of dollars per year.

Chestnut

Chestnut is the first AI mortgage lender. Our AI agents automate the mortgage process and save consumers 0.5%+ in interest.

Founder Spencer Brown’s last startup built software used by a top-10 mortgage lender to power $85B+ of loan volume and all aspects of loan processing. During that time he learned how AI could be used to automate the mortgage process and save consumers billions of dollars per year. Realizing that traditional lenders weren’t poised to adapt to AI, he founded Chestnut to challenge the $128B mortgage market head-on. So far, Chestnut is licensed in Texas and Colorado where we offer several different types of home loans.

We’re backed by Y Combinator, Olive Tree Capital (Uber, Postmates, Ramp), and other world-class investors, angels, and founders. The company was founded in January 2025 and recently completed YC X25.
