I used Looker for years and have always wanted a product priced less for the enterprise and more for developers. I even prototyped a similar tool myself.

Congratulations on the launch. I will be using mprove and will give you feedback along the way.

EDIT: I would love to get in touch with you and learn more about what your plans are. Possibly collaborate if you'd be open to that. I'm [email protected] -- I couldn't find your contact info anywhere!
