These women have enormous potential, and we wouldn’t be surprised to see them on our 40 Under 40 list—or any other Fortune ranking—some point down the line.
Putting together our 40 Under 40 list is always a tough job, but this year it was more difficult than ever. For the first time, our list was entirely new with no repeats from previous years, which means we had 40 new spots to fill — and there were hundreds of great candidates. Making it even more difficult: There were many more high-caliber women candidates than ever before.
Despite being incredibly impressive, the majority of these women didn’t make the final cut. So, we wanted to shine a light on ten of the lesser-known women whose careers we are following with interest. Some you may already know, while others are under-the-radar, but all have enormous potential—and we wouldn’t be surprised to see them appear on our 40 Under 40 list or any of Fortune’s other rankings in the future.
Without further ado, and in no particular order:
Claim to fame: CEO and co-founder, ClassPass; founder and artistic director, Sa Dance
The first version of Kadakia’s start-up—initially called Classitivity—was a huge flop. But that didn’t stop this dancerpreneur from trying again, this time succeeding in a big way. By the end of 2015, ClassPass, which allows members to take classes in multiple studios with one single membership, will be in every major U.S. market and include more than 10,000 locations. Despite the company’s massive growth, Kadakia still makes time for her one true love: dance.
