Copperlane

Athan Zhang spent his early career on Wall Street, watched two startups from the inside, and then did the math: the mortgage industry is a $4 trillion market in the US alone and loan officers are still chasing borrowers for W-2s like it's 1995. So he teamed up with Brianna Lin—COO, operator, the one who keeps things running—and built Copperlane, an AI-native platform that handles the endless back-and-forth so loan officers can actually close loans instead of playing document detective.

Backed by Y Combinator and armed with nearly two decades of combined experience, Copperlane's AI assistant automatically collects docs, asks the right questions, and fills forms so borrowers don't abandon applications halfway through. Upload a W-2 or bank statement and watch it auto-populate every field—no transcription errors, no frustration. Smart forms adapt in real time: VA sections hide for conventional loans, self-employment questions only appear when needed. Borrowers get instant, compliant answers 24/7 without waiting for a callback. It's mortgage origination without the chaos.

The mortgage tech space is crowded, but nobody's building AI-native from day one like this. Copperlane just proving the boring industries are ripe for reinvention—one automated document request at a time. They're in San Francisco and looking for mortgage lenders ready to stop chasing paperwork.
