Vesta Raises $30 Million Series B With Three Customers Among Its Investors

Vesta, a San Francisco mortgage-origination software company, raised $30 million in a round led by Conversion Capital, TechCrunch reported on Thursday. Three of its customers invested, including Pennymac and New American Funding, and the company's newsroom labels the round a Series B.

Citi Ventures and Andreessen Horowitz also took part. The valuation and each investor's cheque were not disclosed. Vesta has raised $85 million in total, TechCrunch says, which squares with the $55 million that a HousingWire profile of chief executive Mike Yu gave before this round.

What a customer-investor changes

When a customer owns equity, its renewal is partly a view on its own holding. TechCrunch does not say how large the customers' stakes are, and the third customer is not named in its report. Vesta's newsroom banner lists New American Funding, Pennymac, NBKC and Andreessen Horowitz, which suggests the third is NBKC, though neither source says so.

The customers are also the evidence for the product. Pennymac reported that moving to Vesta cut its cost to originate loans by 25 percent before it turned on any AI agents, according to HousingWire. The profile lists Pennymac, Upstart and nbkc Bank as customers and says Vesta grew from 64 to 80 employees during the year it covers.

The same pattern, a biggest customer who is also an investor, appeared in Valon's $150 million Series D, where the valuation was about 11 times contracted annual recurring revenue.

The growth figures and what they leave out

TechCrunch reports that Vesta's revenue is up 12 times year over year, and gives no absolute figure. A 12-times rise from a small base is a different fact from a 12-times rise from a large one. HousingWire separately says lender use of Vesta's agents rose 988 percent over three months, about 10.9 times, which measures usage rather than revenue. Both figures come from Vesta or its chief executive.

Yu said the company has under 5 percent of the market and that demand "exploded in the last year," according to TechCrunch.

What the agents do

Vesta's software automates parts of loan origination with AI agents. A mortgage takes about 40 days to close in the U.S. and costs around $11,000 a loan, TechCrunch reports, and Yu said most of that cost is human labour, with a main delay being the wait for a person to review a file.

Lenders choose which tasks to hand to agents. A common path, per TechCrunch, is an agent whose work a person approves, then a share of loans it handles alone, then wider use. Some lenders use the agents for underwriting decisions and remain responsible for them, and every action and its reasoning is logged for audit.

Yu credited Claude Sonnet 4.5 as the breakthrough because it followed customer-configured instructions over long task horizons better than earlier models. Before that, Vesta had spent its time on data architecture. Competitors named by TechCrunch are ICE Mortgage Technology and the AI-native Xpanse. Yu argued that incumbents were not built for agents and that adding them on top is very hard.

The round arrives in a quarter when venture funding fell 25 percent to $159 billion. Vesta's earlier funding was also $30 million: a Series A led by Andreessen Horowitz in January 2022, per FinLedger, which put its total at $35 million then. The next figure to look for is a revenue number, which a customer-investor round makes easier to ask for and has so far not produced.
