Emile Petrone founded Tindie for selfish reasons. "The basic idea was that there wasn't a marketplace for the things I was interested in," he says. At the time, those things were his latest DIY hardware obsessions—specifically, kits to support Arduino and Raspberry Pi. "Ebay's not really right, and neither is Amazon. Hardware projects had no natural home."
So in the summer of 2012, Petrone (then an engineer at a Portland startup) launched a site where flexible matrix boards and laser motion sensors could be sold alongside build-it-yourself weather monitoring kits and robot birds. Almost immediately, Tindie began attracting favorable attention from the indie hardware community—and then expanded from there. Today, around 600 inventors sell more than 3,000 different hardware products, which have shipped out to more than 80 countries around the world.
