Groupon said on Thursday Starbucks Corp Chief Executive Howard Schultz has joined its board of directors and that his venture capital firm has taken a stake in the daily deals website.

Schultz' firm, Maveron, previously invested in retailers such as zulily, which offers daily deals on clothing geared to mothers and their children, and the lucy activewear chain, which was sold to VF Corp in 2007.

Groupon, a fast growing members-only site, reportedly got a $6 billion takeover bid from Google Inc in November, which it turned down. Two-year-old Groupon recently completed a $950 million round of financing.

The company offers its members discounts of 50 percent to 70 percent on local services, provided enough members sign up for any single offer. It takes a commission of 30 percent to 50 percent from the merchants who provide the services.
