I was in the same YC batch as Nikki. The thing I remember most about her was her enthusiasm. I also remember that her presentation on Demo Day got the loudest applause and most interest. Sad to hear 99dresses didn't make it, but I'm sure Nikki will have a bright future. Few young women her age will have gained the experience and insight that comes from founding a company and seeing it fail. As Michael Jordan said "I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."
