Eureka 157: Hexr

Jamie Cook is the founder and CEO of Hexr, a London-based company behind what may be the safest bicycle helmet ever created. For decades, there has been almost no innovation in foam cycling helmets, beyond them becoming more aerodynamic. After five years of research and testing at University College London and Oxford University – and more than 3,200 prototypes – Hexr’s 3D-printed helmets began shipping earlier this month. The firm’s head-scanning app ensures you get a perfect fit.
