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.
Mike Yu is the co-founder and CEO of Vesta, a San Francisco-based startup building an AI-driven, cloud-native loan origination system (LOS) for the mortgage industry. A Stanford-trained product strategist who cut his teeth at Blend - where he helped land the Wells Fargo partnership and became the company's first licensed insurance agent - Yu launched Vesta in November 2020 after recognizing that mortgage infrastructure hadn't fundamentally changed since the 1990s. He has raised $55 million from Andreessen Horowitz, Bain Capital Ventures, and Conversion Capital, and was named a 2024 HousingWire Vanguard and Forbes 30 Under 30 honoree.
