Copperlane, an AI-native mortgage origination platform, has raised $4.1 million in seed funding to scale an autonomous AI mortgage loan officer that aims to compress hours of document reviews into minutes, the company announced.

The round was led by TQ Ventures, with participation from Y Combinator, US News Digital Ventures, Mercor, Valon Mortgage and others.

The company says it has created the first AI mortgage loan officer called Penny that has the ability to autonomously analyze thousands of pages of borrower documents and surface recommendations for human staff by using a generalized AI model to interpret income patterns, assets and credit file nuances.

At the application stage, Penny can scan bank statements for large deposits that fall outside expected income, identify other conditions an underwriter is likely to question and proactively contact the borrower for clarification. The system can also draft letters of explanation before a file reaches underwriting.

The goal is to reduce document review and preapproval analysis from more than four hours per file to a matter of minutes, the company said.

Copperlane was founded by 21-year-olds Athan Zhang, a Princeton University computer science graduate, and Brianna Lin, who studied computer science and real estate at the University of Pennsylvania.

“Mortgage lenders want to build relationships and expand their portfolios, not spend hours each week reviewing or even drowning in dense paperwork,” said Zhang, Copperlane’s co-founder and CEO.

“Better technology for mortgage lenders directly translates into a better experience for borrowers. Our mission is to further democratize mortgages for all Americans so they can take part in the American Dream,” said Lin, co-founder and chief operating officer.

Copperlane did not disclose current customer counts or loan volume running through the platform. For lenders evaluating AI-native tools, proof points around defect rates, repurchase exposure and turn-time improvements relative to traditional workflows will be key benchmarks as the company deploys its new capital.
