Vesta

Vesta is a San Francisco-based B2B SaaS company building the next-generation loan origination system (LOS) for the mortgage industry. Founded in 2020 by ex-Blend engineers Mike Yu and Devon Yang, Vesta replaces legacy mortgage software with a cloud-native, open, rules-driven platform that lets lenders configure workflows, automate compliance checks, and integrate with 40+ ecosystem partners - all without custom code. Backed by Andreessen Horowitz and Pennymac, Vesta tripled its loan volume and customer count year-over-year through 2025.
