This is awesome! My company, Reflect, was looking at building a set of features similar to this but on top of existing data in peoples' systems right before we were acquired.

There's a big market of people who are looking to do simple data science and machine learning but don't know how to get started, don't have a lot of expertise to implement the algorithms, and the required ETL looks really daunting. You could put all of this on rails by looking integrating with existing systems.
