Vesta, an AI-native software startup that helps lenders originate mortgages, announced on Thursday that it raised a $30 million round led by Conversion Capital.
The startup uses AI agents to automate much of the loan origination process, which, the founders say, helps lenders reduce the time and costs of processing mortgages. Three of the company’s customers, including Pennymac and New American Funding, also invested in the round alongside Citi Ventures and Andreessen Horowitz.
Mike Yu co-founded the company in 2020 with Devon Yang. Yu, the company’s CEO, told TechCrunch that now was the perfect time to raise because demand for the product has “exploded in the last year.” He said revenue is up 12x year over year.The company has raised $85 million in funding to date.
“While the traction is great, we are still under 5% market share and now is the time to staff up, take the market, and invest in new product lines,” Yu said.
Those new product lines include a personal assistant for mortgage issuers that can help perform tasks and track workflows. It takes around 40 days to close a mortgage in the U.S., costing around $11,000 per loan. “Most of that cost is human labor, and a major bottleneck in the timeline is just waiting for a person to get to reviewing your loan.”
With Vesta, the idea is to allow humans to deploy a swarm of agents to speed completion of tasks. Customers decide what tasks they want to assign the Vesta agents: “Many of our customers start an AI agent with a person approving its work, then let it handle a share of loans on its own, then expand,” Yu explained, adding that some lenders are even using Vesta AI agents to make mortgage underwriting decisions.
Companies remain responsible for underwriting decisions, he said, regardless of what software or AI agents they use, and Yu added that all actions and reasoning behind a decision are recorded for compliance and to audit AI decisions.
This level of autonomy stems from the vast improvements in AI models in the past year, which weren’t good enough, at that time, to build agents for the complex multi-stage tasks involved in mortgage lending. Before, the company was just focused on building the right data architecture to use the most advanced tools to automate the mortgage process.
“For us, the big breakthrough was [Claude] Sonnet 4.5, which we just found to be much better at adhering to user-configured instructions over the time horizons we need than previous generations,” Yu said.
Vesta is, in many ways, competing against both traditional mortgage systems like ICE Mortgage Technology and other AI-native companies also trying to automate the mortgage lending process, like Xpanse.
At least against legacy incumbents, Yu said Vesta’s advantage is that those companies weren’t built for AI agents, and “putting AI agents on top of them is very hard,” he said. As for what’s next, “our priority is earning the business of the rest of the mortgage industry,” Yu said. “Then, we’ll go wherever our customers take us.”
