Friday Harbor was founded in 2024 by CEO Theo Ellis and CTO Jesse Collins, who met as entrepreneurs-in-residence at the AI2 Incubator. Ellis brings fintech and mortgage experience from roles at Pagaya Technologies and Altisource, while Collins contributes engineering depth from Affirm, Fast, and Zillow. Together they targeted a costly inefficiency in mortgage lending: loan files are typically assembled with incomplete information up front, and problems surface late in the process, slowing closings and inflating origination costs that can run thousands of dollars per loan.
Friday Harbor's platform moves underwriting intelligence to the very start of the loan. Its AI Originator Assistant reads borrower documents, identifies inconsistencies, generates conditions, and walks originators through complex scenarios with the precision of a senior underwriter — day or night. The result is cleaner, more complete loan files that reach fully underwritten outcomes faster, reducing back-and-forth, cutting cycle time, and helping smaller and mid-sized lenders match the speed and efficiency of the largest mortgage banks.
The company serves mortgage lenders, especially community lenders and independent mortgage banks (IMBs) that need to compete with industry giants on turn times without giant operations budgets. By embedding pre-underwriting directly into the originator's workflow and integrating with loan origination systems and point-of-sale platforms, Friday Harbor fits into existing processes rather than forcing a rip-and-replace. It has been adopted by more than 20 lenders, including two of the top 10 IMBs, and was the first mortgage technology provider to receive an AI governance compliance attestation from law firm Brody Gapp.
In April 2025, Friday Harbor raised a $6 million seed round led by Abstract Ventures and Mischief, with participation from Wischoff Ventures and the AI2 Incubator. The capital funds expansion of its engineering team and deeper integrations with mortgage LOS and point-of-sale platforms as it scales its AI underwriting assistant across the lending market.
