The Future of Food Isn't Waste

The Future of Food Isn't Waste

MCJ Startup Series with Mill

Today's guest is Harry Tannenbaum, Co-founder and President at Mill

Mill developed a household bin that not only collects uneaten food but also shrinks and deodorizes it. The company’s solution aims to keep food in the system and prevent it from ending up in landfills or waste systems, which would otherwise generate significant emissions. 

Mill recently exited stealth and we're proud to be multi-time backers of the company through our MCJ Collective venture funds alongside other leading climate tech funds such as Breakthrough Energy Ventures, Lower Carbon Capital, Prelude Ventures, Energy Impact Partners, and John Doerr.

They discuss the qualities of a successful consumer product and how Harry and his co-founder, Matt Rogers, applied the lessons they learned at Nest to their work at Mill. Additionally, they examine Mill's product and logistics framework and the intersection between consumer behavior change and systems change.
