At this year’s Photokina, a photographic and imaging trade fair in Cologne, Germany, HAX partner Benjamin Joffe took the stage to present several lessons he’s learned from the 200 hardware investments he’s observed at HAX. Joffe walked through what investors look for in early-stage startups, how hardware startups move from ideas to scalable products, and other HAX success stories.
