Vesta Raises $30 Million Series B From Three Lenders That Already Use Its Mortgage Software

Vesta, a mortgage origination software company that runs AI agents alongside human loan staff, announced a $30 million Series B on Oct. 8, led by Conversion Capital, according to HousingWire. Total funding is now $85 million, so this round is 35 percent of everything the company has raised. Neither HousingWire nor TechCrunch reports a valuation, and the round was announced rather than shown in a filing.

Three of the investors are customers. New American Funding, PennyMac Financial Services and NBKC Bank put money into the vendor whose system they use, alongside Citi Ventures, FirstKey Mortgage and Navitas Capital. Existing backers Andreessen Horowitz, Zigg Capital, Parker89 and First American Financial's venture arm also took part.

The figures Vesta supplied

Every number about performance in the announcement comes from Vesta or a customer it names, and none is independently verified.

Claim	Figure	Who supplied it
Revenue growth	12x year over year	CEO Mike Yu, to TechCrunch
Share of tasks done by agents or automation	About 40%	Vesta, via HousingWire
Mortgages originated by lenders on or moving to Vesta	More than $100 billion a year	Vesta, via HousingWire
PennyMac cost to originate	Down 25%	PennyMac, via Vesta
Market share	Under 5%	Yu, to TechCrunch

The 12x figure comes with no revenue base. Twelve times a small number is still a small number, and the company has not said what the starting year looked like. Yu's under-5-percent market share is likewise given without a denominator, so it cannot be tied to the $100 billion figure.

PennyMac is the cleanest data point and also the most entangled one. HousingWire reports that it replaced its prior origination system with Vesta and saw a 25 percent drop in cost to originate and roughly 50 percent efficiency gains for loan officers before it switched on any AI agents. It has held a minority equity stake in Vesta since a partnership that began in September 2025. The customer supplying the evidence is also an owner.

What the agents do and who answers for them

Lenders choose which tasks the agents take. TechCrunch describes a common path: an agent starts with a person approving its work, takes a share of loans on its own, then widens its role. HousingWire lists the configurable jobs as document review, data validation, cross-checks, underwriting decisions, condition clearing and closing package review.

Some lenders let Vesta agents make underwriting decisions. Lenders stay responsible for those decisions, TechCrunch reports, and Vesta logs every action and its reasoning for compliance and AI audit purposes. That log is Vesta's answer to compliance reviews; none of the coverage describes a regulator testing it.

Yu credits Anthropic's Claude Sonnet 4.5 as the breakthrough, saying it follows user-configured instructions over the long time horizons mortgage work needs better than earlier models did. Vesta competes with ICE Mortgage Technology and with AI-native rivals such as Xpanse, per TechCrunch.

The cost the pitch is aimed at

TechCrunch puts the cost of closing a U.S. mortgage at about 40 days and about $11,000 a loan, mostly human labor. HousingWire cites the Mortgage Bankers Association as reporting origination costs well above $10,000 a loan. Christian Lawless, Conversion Capital's founder and managing partner, said: "We believe this is the operating architecture the mortgage industry has been waiting for."

Other agent-company rounds on this desk, such as Supabase's raise and Turso acquisition and TypeSafe AI's $870 million, are pitched at developers. Vesta's pitch is to lenders around a cost target, and the weak point is that three of those lenders are also its investors.

The next observable event is the first lender to name a share of loans it now decides without a human reviewer. Vesta says it is hiring across engineering, implementation and go-to-market, and no revenue figure has been attached to the round.
