New York-based blind date startup Grouper—think Uber, for yuppie polyamory—is down another key member: sources tell me CTO and co-founder Tom Brown is out of the dating game.

Brown was described by one source as "the smart one" at Grouper, which as of last year had expanded into 20 different cities. But this same source also told me "the [Grouper] product is shit," the company has already "laid off half the people," and while "they still have some cash," co-founder "Mike [Waxman] was spending way to much money."

Grouper has not replied to repeated requests for comment, nor has Brown, who announced his relocation to San Francisco on Facebook.
