Hello,
Based on the info you’ve provided, pPrograms that I’d consider likely good fits and
reasonable reaches, would be MIT Sloan, NYU Stern (they have stellar resources for entrepreneurship, more than is commonly known), and Kellogg (you can select more than one concentration, and could do both Social Enterprise and Innovation & Entrepreneurship).
For more on-par level programs, I’d suggest looking at UNC Kenan-Flagler and UCLA Anderson.
Since you currently operate an ongoing venture, in your applications make clear what will happen to it while you are pursuing a full-time MBA – will someone else handle daily operations? Be sure not to give the impression that you expect to run the company while doing the MBA!
