In the late 1980s, Curt Jones was working in a Kentucky lab, using liquid nitrogen to flash-freeze animal feed. He wondered if he could re-invigorate his favorite dessert by pouring droplets of ice cream into a vat of liquid nitrogen and – voila! – out came cold and creamy pellets that he soon branded Dippin' Dots. The novelty treat spread to fairs, stadiums and shopping malls, and eventually grew...

In the late 80s, brothers Bert and John Jacobs were living as nomads, traveling from college to college selling t-shirts out of their van. It wasn't a sustainable living – until one day, they created a new design. It was a simple sketch of a grinning face, with three words printed underneath: Life Is Good. The optimistic message was deeply personal to the brothers, who grew up in what they describ...

At first, they popped kettle corn in front of local supermarkets in th...

In 2004, two former Paypal engineers, Jeremy Stoppelman and Russ Simmons, were spit-balling new internet ideas.

Growing up, Tim Brown discovered he was very good at two things: design and soccer. While playing professional soccer in New Zealand, he was turned off by the flashy logos on most athletic gear. He started making simple canvas shoes for his teammates, but soon discovered a better material: soft merino wool from his country's plentiful sheep. Meanwhile, on the other side of the world, his future bu...

Seth Tibbott may be the only founder in the world who grew his business while living in a barn, a teepee, and a treehouse. His off-the-grid lifestyle helped him save money as he started to sell tempeh, a protein made of fermented soybeans.

Chet Pipkin was the kind of kid who loved to take things apart and put them back together. As a young man in the early 1980s, he started hanging out in mom-and-pop computer shops, where he realized he could meet a growing need by selling the cables that connect computers to printers. That simple idea became the main ingredient in Chet's secret sauce: instead of making his own computers, he would m...
