Harry Tannenbaum

Harry Tannenbaum is the co-founder and President of Mill, a waste prevention technology company rethinking how waste is managed, starting with food. Mill builds systems and infrastructure that turn food scraps that are typically sent to landfill into a valuable, usable resource.

Mill’s residential food recycler is now in tens of thousands of homes, creating the foundation for Mill Commercial, the company’s end-to-end solution for businesses. Mill Commercial pre-processes and analyzes food waste streams on-site, helping organizations reduce waste, gain operational efficiencies, and unlock new value from what was once discarded.

Prior to Mill, Harry led the centralized analytics group and ecommerce business at Nest, which launched the first learning thermostat and became the leading brand for the connected home. During his time at Nest, Harry helped to scale the business to more than $1B in annual revenue. Following Nest’s acquisition by Google, he was a director in Google’s hardware organization focused on ecommerce and subscription offerings. Before Nest, Harry briefly worked at an investment bank, before deciding he wanted to work in climate.

He received his bachelor’s degree in Economics from UCLA. Harry is a surfer, and was raised in San Francisco.
