iReTron is a service that buys, refurbishes, donates, and resells used electronic devices (cell phones, cameras, tablets). Customers get an online quote from iReTron, ship their devices (for free) and then get paid within two days. The founder of iReTron, 16-year-old Jason Li of Los Gatos, California, pitched his business on Shark Tank in 2014. He closed the deal with Barbara Corcoran and Mark Cuban ($100,000 for 10 percent equity) one month after filming the episode.
Since Shark Tank, iReTron continues to provide its initial services but has also expanded to become an online source of information regarding wireless technology. Li, who went on to study economics and computer science at the University of Chicago, launched another start-up called UProspie, a web platform that lets prospective students arrange meetings with real college students. As of February 2017, Li has also been working as a product designer at the media platform Flipside, where he leads design and development for UI/UX.
