Vesta raises $30M to scale AI agents built for mortgage lenders
The San Francisco startup's round, led by Conversion Capital, bets that software agents can take over the paperwork-heavy grind of loan origination
Vesta, an AI-native software startup that helps lenders originate mortgages, has raised a $30 million round led by Conversion Capital.
What Vesta actually does
Vesta builds a loan origination system, or LOS. Think of an LOS as the central nervous system of a mortgage lender.
It is the software where loan data, borrower documents and approval workflows all live. Every application passes through it, from first submission to final funding.
Vesta’s version is designed around a mix of AI agents and human staff. The agents take on tasks like reviewing documents and making underwriting decisions. Humans step in when something falls outside the normal pattern.
The company was founded in 2020 in San Francisco by Mike Yu, who serves as CEO, and Devon Yang, who serves as CTO. Its stated focus is modernizing mortgage workflows through automation rather than layering new tools onto old manual processes.
The numbers behind the pitch
Lenders saw origination costs fall by up to 25% in 2026, according to the company’s reported figures.

AI agent usage on the platform grew by 988% over three months in 2026.
Vesta’s customer and partner list includes some recognizable names in mortgage lending. The company has worked with Pennymac, Verus Mortgage Capital and New American Funding.
On the technology side, Vesta integrates with nCino, Blend and Argyle.
What this means
Vesta’s human-in-the-loop design keeps people responsible for exceptions, giving lenders a check on the software.
The partnerships with Pennymac, Verus Mortgage Capital and New American Funding give Vesta credibility with peers who want proof before they commit. Its integrations with nCino, Blend and Argyle make it easier for those peers to try the product without a full overhaul.
