TECH CRUNCH - May 30 - Grouper has been around since 2011. The service matches users with singles they may enjoy canoodling with, but asks that each party bring two of their friends for a group date. Grouper was founded by Michael Waxman. In his opinion, Grouper has a leg up on the competition because it facilitates real-life meeting, whereas traditional dating sites and social networks are more focused on letting you message and look at photos.
