How An Entrepreneur Prepares For The Most Important Day Of Her Life

Y Combinator is one of the most competitive startup incubators in the country. Thousands apply, but only 47 startups are in the current class.

One of those startups is StyleUp, co-founded by Kendall Herbst and Ryan Choi. The site is essentially a style assistant: Every morning, users get an email with an outfit that matches their personal style and works with the local weather.

"We help women who are interested in fashion but don’t have time to read a 500-page magazine," says Herbst, who met Choi at MIT Sloan and moved from Cambridge, MA to Mountain View, CA this January to attend Y Combinator.

The intense three-month program culminates in "Demo Day," where startups pitch to investors, which was on Tuesday. Herbst took a camera around with her this past week and offered to share her experience with Business Insider.
