The challenge
A top-10 US mortgage lender ran a legacy origination platform that had been incrementally extended for 30 years. The result: 11 days to decision (median), 32% straight-through processing, and a borrower-experience NPS at industry-laggard levels. Online-only fintechs were quoting 24-hour decisions on conforming loans and winning the best-credit segment.
What Mergen delivered
A complete origination redesign on Salesforce Financial Services Cloud, with Mergen DocAI (custom-trained on 4 years of the lender’s document corpus) handling pay stubs, tax returns, bank statements, and property documentation. The borrower experience was rebuilt from the URL outward with a single sign-in, real-time status, and explicit human-in-loop touchpoints designed to feel like service, not friction.
Build approach
3-month discovery covering the existing platform’s 14 critical workflows
Greenfield build on Salesforce FSC + custom Lightning components for underwriting workbench
DocAI service exposed via API to FSC + the underwriter UI
Phased rollout: motor-vehicle simple-refi first (lowest risk), then conforming purchase, then jumbo
9-month total elapsed time to full production, including legacy decommissioning
The outcomes
Time-to-decision compressed from 11 days to 36 hours (median)
Straight-through processing rate up from 32% to 85% within two quarters
