PillPack

As a teenager working in his parents' pharmacy, TJ Parker saw first-hand the frustration of patients taking multiple medications. Twelve years later, after a completing a doctorate in pharmacy, a term at TechStars, a stint at Ideo, and raising $63 million, Parker and co-founder Elliot Cohen found the answer: An online pharmacy that packages pills according to when they need to be taken. "I spent a lot of time trying to see if there was a widget or a physical product or a piece of software that would fix this," says Parker. "But most of the frustration is intrinsically wrapped up in the pharmacy." PillPack hopes to eliminate that frustration not just with clever packaging, but by coordinating refills on behalf of its customers, offering its service for free (the average customer takes seven medications, which Parker says gives PillPack plenty of margin), shipping overnight, and making it easy to transfer prescriptions to PillPack.
