Hello trying11, and thanks for your post.
We are happy to evaluate your profile. The application process is truly holistic, and committees will look at your stats (GPA and GMAT), work experience, and extracurriculars.
Your GPA is strong, so that is a good start. Your GMAT Focus is also strong, and compared to others in your demographic, it should be a bit above average, which is good too. You may still want to illustrate to the schools that you have the academic ability to succeed in the classroom. You could showcase your quant ability in your resume, and your recommenders could do the same in their recommendations.
It is hard to gauge your work experience without knowing your specific accomplishments and impact you have made there. But you seem to have shown leadership experience at MBB, and of course in your work at startups. Ideally this will be supported by strong recommendation letters as well, so choose your recommenders carefully. It will also be important to explain why you actually need an MBA and what skills you will gain. Be sure your story makes sense, and is realistic and specific.
Regarding extracurriculars, make sure to really emphasize your leadership roles you have taken on. Building the community of startups founders sounds impressive; that is one aspect of your profile on which you can elaborate.
You really have a very solid profile, and you do have a chance at some of these schools. You have a good list so far. However, they are extremely competitive, especially given your demographics, and each school simply does not have the room to admit all the world's qualified applicants. For that reason, I suggest apply to others. Be sure to include reach, target and safer choices. Hopefully they will see that you have a compelling story and are someone who will add value to the classroom and community.
Good luck!
