The next Mark Zuckerberg

You know Facebook founder Mark Zuckerberg and Twitter co-founder Jack Dorsey, but there's a changing guard of entrepreneurs focused on big ideas and the next big thing. Here's a batch to look out for.

Nat Turner - Flatiron

When Nat Turner's seven year old cousin was diagnosed with Leukemia, he and Flatiron co-founder Zachary Weinberg got the inspiration to use big data to improve cancer treatment.

Flatiron is trying to help oncologists by aggregating treatment data from cancer centers across the country. The idea is to give doctors a platform they can use to compare treatments for patients with similar diagnoses.

"If you're diagnosed in Augusta, Georgia, the system can leverage all the different data collected across the United States to compare," Turner says. "We're just now starting to return results back to the centers to say, 'did you know these four or five treatments are working better than you thought, on patients that you didn't expect?"
