Thanks for the additional details. The fact that you have shortcomings isn't the issue. The reason I pushed a bit on your start-up experience was to understand its significance within your profile. Sounds like you attracted a decent number of users. Even if you didn't obtain venture funding, did you at least earn any revenue?
It sounds like you have a role as a product manager at a start-up now. So, why do you want an MBA just to get the same job elsewhere? At this point, you should try and hone in on a specific long-term goal. Many folks talk a bit game about starting their own company later on, so what makes you different? Having a solid, precise goal and a plan to get there will make you stand out of the crowd.
With these open questions, I still don't have a solid handle on your profile. Based on the information you provided thus far, my original thought that you're a bit behind the pack at Haas, Kellogg, and Yale - less so at UCLA - still stands. Are these programs worth applying to? Probably. I would consider applying to about 4 schools - one can be a stretch, you should stick with UCLA, and identify a couple more that align well with your short and long-term goals. Hope this information helps. Feel free to get back to us with the answers to the above questions. Also, feel free to check out
