TemperPack

In 2014, James McGoff and Charles Vincent--students at McGill University's materials-engineering program--and Brian Powers, a recent University of Pennsylvania grad, founded TemperPack, which makes Styrofoam-free insulation that keeps products cold during shipping. (Think: a customized cooler inside a packing box.) They started by "cutting strips of fiberglass and sealing them inside plastic... it wasn't a true innova- tion," understates McGoff. Still, in 2015, TemperPack negotiated a $100,000 trial run with the meal-kit giant HelloFresh. Plated signed on too, once TemperPack started using jute, a compostable insulation material. "Food companies were desperate to not use plastic and Styrofoam," says Powers. In February 2019, grocery giant Albertsons Companies started using TemperPack's newest recyclable insulation, called ClimaCell, for its drug-delivery business. This year, TemperPack is expected to double revenue, to around $50 million. --Diana Ransom
