This is a good route to take and the same one I took after leaving undergrad. An MBA is for the birds, anyways ;)

First things first, take credit where credit is due! You're a founder now it sounds like, and you're working on your first MVP I'm guessing (hoping?) as well. At the very least, get together some sketches, etc... as well. You'll definitely want a prototype in order to feel "whole."

So, more importantly, just list this startup's name as a part of your career in your resume as you would when working for any other company. When asked, be completely truthful, and let your exuberance and fascination with being a self starter shine through. These few factors alone will signal to any future employer that you would be a valuable asset to have on their team, but you may find that you enjoy working for yourself a bit too much before then ;)

Have you setup a corporation or LLC yet? Or are you using a partnership (assuming this is all U.S. based)? Once you have your business' infrastructure in place, things will definitely feel more official as well. Also, be sure to incorporate NOW rather than later to avoid any major legal headaches.

Feel free to message me any time if you'd like to chat further.

Cheers,
