I didn't mean to imply that I am picking a partner to satisfy YC....that never crossed my mind! However, I highly value the experience and advice coming from YC partners, therefore, the fact that they place such high importance on having a technical co-founder made me question whether I needed to add a 3rd partner if the two of us don't cover enough "technical" ground. That being said, I now have a new question. I have officially made the partnership with her and I'm so excited about it! I just don't think I could possibly have a better partner. She is as motivated and hard-working as I am and we're up until 1AM every night working on our company. The problem is that I would like to add her to my YC application and I can't access to it anymore. What's the best way to get the message to YC?
