About ONpro
ONpro was born from a simple observation: Complexity in capital markets is often artificial.
When corporate entities raise senior debt finance, the "onboarding" process creates massive friction. A single client might interact with 20 different financial institutions, each asking the same questions in slightly different ways.
We believe there is a better way. By creating a unified Master Schema for onboarding data, we can eliminate duplication, reduce errors, and dramatically speed up time-to-execution for deals.
