About
Grouper is a social club that sets up drinks between 2 groups of friends: 3 guys and 3 girls (or 3 guys and 3 guys, etc.). Grouper started in New York in the summer of 2011 and now organizes Groupers in major cities across the US. Members have shared tens of thousands of drinks. The company was founded by Michael Waxman, a Yale grad and developer who formerly started language-learning company Batiq, and Tom Brown, an MIT engineer who was an early employee at MoPub (acquired by Twitter for 350MM). The founding team also includes Challen Hodson and Kristen Badal. Grouper was funded by Y Combinator in the Winter 2012 batch.
