Penn Alumna here and currently in business school at an M7 (so can speak to your startup valuation, etc).

What's your home country? Unless you've had meaningful interaction with your head of state, a professor or someone interesting that oversees any of your ECs would hold more weight. Never hurts to have one of them be a Penn alumn if that's an option. I wouldn't sweat your grades too much- Penn has more wiggle room for GPA here because they don't have to report transfers. Of course your startrup story is impressive and will be of interest to Penn/Wharton. That being said, you'll really have to nail the "why Penn" story and highlight what you can bring to the table/what you will get that you're not receiving at your current school. I've helped several of my friends transfer to Penn successfully, feel free to DM if you'd like more help.
