Copperlane is an AI-native loan origination system. Our AI agent, Penny, optimizes rate pricing, guides borrowers, and verifies documents - cutting loan processing time from hours to seconds.
Hey PH! I’m Brianna, co-founder of Copperlane (YC W26)!
The Problem Lenders spend $11,800 to originate a mortgage, and the majority of that cost is burned during intake due to missing documents, back-and-forth, and costly errors. This manual process breaks down on almost every loan, across 8 million loans a year.
Existing tools fall into two approaches:
❌ Legacy portals – These systems are decades old, and loan officers need to chase down borrowers for docs manually.
❌ AI built by older mortgage teams – Our competitors are all mortgage people trying to build AI. We’re the only AI people learning about and building for mortgage. :)
My co-founder and I both come from mortgage families (Freddie, Fannie, FHA), so the space is personal to us and we built Copperlane to fix it.
How Copperlane is Different 🚀 Copperlane is an AI-native loan origination system powered by our agent, Penny, who behaves like a real loan officer.
🔸 Penny handles intake proactively – She pulls borrower docs, reads them, and checks the borrower’s loan eligibility. 🔸 Guides borrowers through the application – Penny answers questions and proactively helps borrowers complete the loan application correctly. 🔸 Proactively fixes issues – Is the borrower missing a paystub? Or reported conflicting income? Penny flags it immediately and follows up with the borrower. 🔸 Delivers clean files to lenders – Loan officers receive clear, organized files and can focus on bringing in new loans.
Who this is for If you’re a lender or loan officer dealing with slow intake, Penny helps you close loans faster without extra headcount.

How does Penny handle complex or non-standard borrower scenarios, such as self-employment income or inconsistent documentation, while ensuring full compliance with mortgage lending regulations?
this is awesome! i came from linkedin :) i was wondering whats the most exciting thing you’re looking forward to regarding copperlane’s launch?
The document verification piece is what catches my attention — that's historically been the biggest bottleneck in loan processing, not the rate calculation. Curious how Penny handles edge cases like inconsistent income documentation for self-employed borrowers, that's usually where automated systems fall apart and a human has to step back in. If you've solved that reliably this could be genuinely transformative for smaller lenders who can't afford large underwriting teams.
The "AI people learning mortgage" vs "mortgage people trying to build AI" framing is sharp and honest. Having Penny proactively flag issues like missing paystubs instead of waiting for a loan officer to catch it manually is where the real time savings happen. Congrats on YC W26, Brianna and Athan.
Congrats Brianna! It’s really useful and smartly focused on one specific niche. All the best here!
What usually kills these flows is the resend-this-doc loop. Copperlane looks strongest where it flags edge cases before underwriting, because W-2 auto-fill matters less than giving ops one clean place to clear missing docs and big deposits.
The mortgage process is still incredibly manual, so this feels like a meaningful use of AI. Having an agent that can guide borrowers, verify documents, and move the process forward automatically could save a lot of time for loan teams.
I’m curious how Penny handles complex cases where financial documents don’t perfectly match or need manual clarification.
Congrats on the launch.
It solves a real pain point. I am curious to know how your underlying system is going to manage the high amount of context so that it does not hallucinate. Amazing work!
Hey Brianna, coming from mortgage families at Freddie, Fannie, and FHA, you must have seen this intake chaos up close for years. Was there a specific loan or moment where you watched the back and forth over missing docs drag on way too long and thought why is this still so broken?
