New York-based startup Copperlane has raised $4.1 million in seed funding to support the development of its AI-powered mortgage origination platform.
The funding round was led by TQ Ventures. Other participants included Y Combinator, US News Digital Ventures, Mercor, and Valon Mortgage.
Copperlane said the new capital will help the company expand operations and improve its autonomous mortgage software. The startup also plans to accelerate the development of tools designed to reduce mortgage pre-approval timelines.
Founded by Athan Zhang and Brianna Lin, Copperlane develops an AI-based mortgage loan officer platform called “Penny.” The software is designed to process borrower financial data, including assets, credit history, and income records.
According to the company, the platform can generate underwriting recommendations and prepare explanations for compliance teams. The system aims to reduce manual work during the mortgage approval process.
Copperlane, part of Y Combinator’s Winter 2026 batch, officially launched its automated mortgage processing engine in June 2026.
