Gabe Newell is known to most as the co-founder and de facto leader of Valve, but did you know he also invests in cookery startups? Eater recently interviewed Newell over the phone, where he told a story about how a Seattle-based startup by the name of ChefSteps asked him if they could come to his home and cook food for him and his son. The food was made using Joule, a nifty kitchen peripheral that Newell was so impressed with that he decided to not only personally fund the startup, but even made a cameo appearance in their new commercial.
