AI-native loan origination system built around Penny, an autonomous AI agent that automates intake, document verification, rate pricing, and borrower guidance, cutting the $11,800 industry-standard cost per loan origination.
Penny pulls borrower documents, reads them, checks borrower loan eligibility, pre-verifies documents, dynamically presents form fields based on borrower profiles, and delivers complete organized loan files to human officers. Eliminates manual data entry errors across 8 million loans per year. Cuts document chasing by 75%. Launched on Product Hunt. Focused on residential mortgages initially, open to commercial loans in the future.
Brianna Lin also co-founded Q2Q (YC W26), getting into YC twice for the same batch (per her LinkedIn). Athan Zhang also listed as co-founder of Coevolved (YC) for mortgage origination agents. Both founders come from mortgage families (Freddie, Fannie, FHA), giving deep personal connection to the space. Likely investing in NLP/document understanding and expanding LOS integrations. Mid-sized lenders as initial target.
AI agent Penny automatically extracts, classifies, and verifies mortgage documents, eliminating manual data entry and pre-catching errors before files reach loan officers.
Instead of a loan officer manually reading through stacks of pay stubs and tax returns, Copperlane's AI reads them instantly, fills out all the right forms, and flags anything wrong before a human ever sees it.
It's like having a paralegal who never sleeps, reads 1,000 pages per second, and actually enjoys filling out paperwork perfectly.
Penny proactively guides borrowers through the mortgage application, clarifying requirements, prompting correct uploads, and resolving issues in real time before they become costly delays.
Instead of getting a confusing email asking for proof of income, borrowers chat with Penny, who explains exactly what's needed, checks their uploads instantly, and tells them if something's missing or unclear.
It's like GPS navigation for your mortgage—instead of handing you a paper map and saying good luck, Penny gives you turn-by-turn directions and reroutes you if you make a wrong turn.
AI-driven pricing engine optimizes mortgage rate quotes in real time, forecasting borrower behavior and market conditions to maximize lender competitiveness and close rates.
Instead of a loan officer manually checking rate sheets and guessing what to offer, the AI watches the market and borrower profile in real time, automatically suggesting the best rate to win the deal.
It's like a stock trader who watches every mortgage rate in the country and whispers in your ear, Offer 6.75%—you'll win this deal and still make money.
AI automates compliance reminders, scheduling, and workflow routing while flagging anomalies in borrower activity or expense patterns.
The AI keeps track of every deadline, sends reminders automatically, and raises a flag if something looks off—like a sudden big deposit or missing document—so nothing slips through the cracks.
It's like a hyper-vigilant office manager who never forgets a deadline, notices if someone's paycheck looks weird, and taps you on the shoulder before it becomes a problem.
Both founders grew up in mortgage families (Freddie Mac, Fannie Mae, FHA), combining deep industry roots with technical and financial expertise. As Brianna noted: "We're the only AI people learning about and building for mortgage" — versus competitors who are "mortgage people trying to build AI." Brianna also co-founded Q2Q (YC W26), getting into YC twice for the same batch.
