Vesta

Vesta is an AI-native mortgage Loan Origination System (LOS) — a modern, open system-of-record platform that orchestrates the loan manufacturing process through configurable software workflows and AI agents that run real loans end to end. Founded in 2020 by former Blend employees Mike Yu and Devon Yang and headquartered in San Francisco, Vesta gives mortgage lenders a cloud, API-and-integration-friendly LOS to replace legacy origination systems, connecting to the broader mortgage technology ecosystem. The company raised an Andreessen Horowitz (a16z)-led Series A. Vesta sells to lenders through a demo/partner-signup enterprise motion and does not currently expose a public self-serve developer API, portal, or documentation surface.

Vesta is profiled on the APIs.io network. Tagged areas include Company, Mortgage, Lending, Loan Origination System, and Fintech.

Vesta’s developer surface includes engineering blog and 7 more developer resources.
