The problem we solve
We unlock open data that describes lender and consumer behavior in the local market and we make it accessible to a wide range of stakeholders.
Our Innovation
One word – microdata. Or the ability to analyze data at a very granular level with accuracy, consistency, and speed (instantly).
Need vs. Want
You can't afford to navigate blind:

  • What's on the surface (where are your competitors)?
  • What's below the surface (where are your customers)?
