Agentic Mortgage Origination

What is your company going to make? Please describe your product and what it does or will do.

We built an AI agent platform that helps mortgage lenders speed up loan applications and reduce errors. Our AI reads applicants' profiles, verifies their submitted documents, and performs initial underwriting checks automatically, cutting weeks off the process.

Where do you live now, and where would the company be based after YC?

We live in San Francisco and plan to keep the company based here after YC.

Explain your decision regarding location.

San Francisco is where we live and where our industry contacts are, so it makes sense to be close to early customers and collaborators in mortgage tech.
