From Yelp CEO Jeremy Stoppelman:
It is unconscionable to imagine that Yelp would create, maintain, or expand a significant business presence in any state that encouraged discrimination by businesses against our employees, or consumers at large. I encourage states that are considering passing laws like the one rejected by Arizona or adopted by Indiana to reconsider and abandon these discriminatory actions. (We’re looking at you, Arkansas.) I hope that in the future the legislatures in the nineteen states that have these laws on the books will reconsider their actions. In the mean time, Yelp will make every effort to expand its corporate presence only in states that do not have these laws allowing for discrimination on the books. I also hope that other companies will draw a similar line in the sand for equality on behalf of their employees and the greater public to persuade legislators to do the right thing and stop or rescind these harmful laws.
San Francisco-based Yelp went public in 2012 and says it will gross about $575M this year.
