The Playmakers

Payal Kadakia wants to get people dancing, spinning, rowing -- and off their couches.

Kadakia, 32, is the founder and CEO of ClassPass, which bills itself as an alternative to the confines of gym memberships. For $99 a month, members can go to unlimited classes within a network of 5,000 boutique studios and gyms. The startup pays studios about 50% of the regular class price.

"I've been a dancer all my life," said Kadakia, who is based in New York City. "When you're really passionate about something, you want to share it with people."

Though it's not yet profitable, it is a growing entity. Since launching in 2013, ClassPass has raised $54 million in funding and it recently acquired San Francisco competitor fitmob. It operates in 32 markets, including London, Vancouver and Toronto.

"The number one thing is, we've gotten people to commit," she said. "[And] most game-changing companies are changing behaviors." -- S.O.
