Hey there,
I'd love to help you out but Leah's right - we need a bit more info. What did you DO for these start ups? What's being a CMO for your family's business entail? How are these companies doing? For the family business, what kind of impact have you had? Not only is that important for your story, it would also help me figure out if your lack of ECs is understandable or not. Entrepreneurs tend to be light on ECs on average and, for some, it's understandable. Especially if the company is growing like a weed!
I'd love to help you out here but it would be awesome if you could share more about your experiences! The more you share, the more useful my response. If you'd rather not share some of that info here, that's fine. Sign up to chat with us
[here]. Sometimes folks don't want to post too much on a forum and that's fine!
Oh, also, have you set a date for the GMAT yet?
Looking forward to hearing more about these companies of yours!
Bhavik
