Yelp

Yelp, a San Francisco-based company whose website and app lets people explore and post reviews of local businesses, has all the bells and whistles you'd expect from a Silicon Valley company that has to compete for the best employees: from weekly get-togethers over beer, to semi-annual costume parties, to a comprehensive health plan that even covers fertility plans, and everything in between. Says one Yelp employee: "I think it is really unique that our CEO comes to work every day and sits on the open floor. Also, we have a barista! This is so cool. You can easily grab a great cup of coffee with a team member.” Read the Great Place to Work review here.
