Vesta Building Mortgage System of Record
Mike Yu, CEO of Vesta, on building a new system of record for the mortgage industry
The real opening is not nicer mortgage software, it is control over the workflow layer that every lender still runs through legacy cores. For most lenders, the loan origination system is the back office system where applications, documents, underwriting tasks, and closing checks all live. Because that core has barely been rebuilt since the late 1990s, newer mortgage tech mostly grew up as point tools around it, which leaves a big gap for a modern system of record that can coordinate the whole process in code.

The old model is a digital filing cabinet plus a lot of human judgment. A processor, underwriter, closer, and post close QC team can each recheck the same file, which is why mortgage origination can involve five or six passes over the same documents instead of one software driven flow.
-
That architecture shaped the market. Front end players like Blend, Floify, and SimpleNexus focused on borrower intake, while newer infrastructure companies like Polly attacked pricing. Even digital closing companies like Snapdocs sit beside the LOS, while ICE Mortgage Technology and Black Knight remained the heavyweight incumbent origination platforms.
-
Replacing a core is hard, but mortgage LOS data turns over fast. Loans usually move through origination and then leave the system after closing, which lets lenders run the old and new systems in parallel for a period and let the old book drain. That makes a core swap more practical than in systems that must preserve decades of active records.
The next phase of mortgage software is likely to look more modular, with lenders choosing their own pricing, compliance, closing, and borrower experience tools around a more open core. If that shift continues, the company that owns the system of record will become the control point for how mortgage work gets automated, integrated, and priced across the stack.
