Priority Bicycles founder Dave Weiner quit his job as a software CEO to pursue a risky idea: building a new kind of bike. In 2014, he started sourcing parts to make his first low-maintenance model, with a rust-proof aluminum frame and a carbon fiber belt drive instead of a chain. Dave was able to keep costs down by selling DTC, but had to scramble to meet demand when his first Kickstarter campaign yielded 1500 orders. From there, Priority pedaled forward steadily, adding new models, and partneri...

Fueled by a bad experience buying freezer-burned popsicles off a battered ice cream truck, he built a custom-made vehicle with a tropical vibe and a built-in “Flavorwave” that let cust...

Freshpet co-founder Scott Morris helped transform pet food by sidestepping traditional kibble and cans, and making slice-and-serve meals that almost looked palatable enough for humans.

So Freshpet provided its own refrigerators, a logistical nightmare that nearly ground the business to a halt. More than 30,000 refrigerators later,...
