While zoning out in math class one day, Quirky founder Ben Kaufman had an idea for a headphone design that would hide his earbud wires and allow him to listen to music in lecture completely undetected. This idea spawned an even bigger idea: Great inventions can come from anyone. Kaufman launched Quirky in 2009, a startup that takes user-submitted designs for new inventions and brings the most popular ideas to life with the help of in-house product designers and an online community.
