Most people get one good call. They pick the right trend at the right time, ride it hard, and spend the rest of their career explaining how they did it. Prabhav Jain has made three bets and is working on his fourth. The difference between him and the people explaining themselves at conferences is that he was writing code at the same time.
In 2009, as a high school student at Torrey Pines in San Diego, he launched EasyDefine - a vocabulary lookup tool that sounds modest until you hear the number: 290,000 users across 185 countries before he even graduated from MIT. That is not a school project. That is a product. When he showed up in Cambridge in 2010, he already knew what product-market fit felt like.
At MIT he split his time between a computer science degree and a research position at the Media Lab's Fluid Interfaces Group - the kind of lab where the walls are covered in whiteboards and nobody talks about TAM. He also interned at Microsoft and placed in the top ten at HackMIT 2013 with a project called PillowPal. He graduated in 2013 with a B.S. in Computer Science and Engineering and immediately co-founded his first real company.
