Stefan Kalb

CEO & Co-Founder, Shelf Engine

Stefan is the Co-Founder and CEO who leads the talented Shelf Engine team. Stefan started his career in the food industry in 2009 when he founded Molly’s, a grab & go food company. While growing Molly's to over 400 regional retail locations, he encountered the problem of food waste first hand. Hungry for a better solution, Stefan co-founded Shelf Engine in 2016. He studied actuarial science and earned a degree in mathematics and economics from Western Washington University. Stefan feels most inspired by data showing the dramatic reduction of food waste and simultaneous business benefit that Shelf Engine makes possible for customers. His favorite thing about working at Shelf Engine is the team's tireless ability to innovate at warp speeds. When Stefan isn't making it happen at Shelf Engine, you can find him with his wife hunting for fresh tracks, on WhatsApp catching up with his family in France, or baking bread at 2am.
