Co-founder and CEO, Yelp

Jeremy Stoppelman is the CEO of Yelp and in March 2012 he took his company public.

After a successful first day on the stock market, the stock bounced up and down for months, particularly around Facebook's Graph Search announcement.

Still, Yelp was able to secure a partnership with Apple Maps, and its site grew to 84 million uniques per quarter.
