Delinquency reduction and automation software

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

We are building software to help institutional landlords reduce delinquency, starting with tools to detect and prevent rental fraud. Our product automates risky workflows and gives landlords better visibility into tenant behaviors that lead to missed payments.

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

We live in New York, NY, and plan to keep the company based there after YC.

Explain your decision regarding location.

We focus on New York because it's home and a major hub for institutional real estate where landlords face chronic delinquency. Staying local keeps us close to early customers.
