Gabrielle (Ellie) Rubenstein

CEO, Co-Founder

As the Co-Founder and CEO of Manna Tree, Ellie is a passionate investor focused on improving human health. Manna Tree invests in growth stage businesses transforming the food supply chain for healthier outcomes. Ellie is a member of the firm’s Executive and Investment Committees. She shapes the firm’s vision strategy and investment products and develops Manna Tree’s global network. For the past 10 years, Ellie has studied the evolution of the food and beverage supply chain, as well as the increasing consumer demand for healthier alternatives.  

Prior to founding Manna Tree, Ellie helped develop the impact investing thesis for a family investment office well known for ESG driven strategies. As part of new product development for the office, she helped launch the first ever arctic asset manager based in Alaska. This established her early belief in the power of impact investing to address social challenges without sacrificing returns, as well as the importance of energy and food as asset classes.  

In addition to her role at Manna Tree, Ellie is an active philanthropist. Through her family office, Mission: Ingredients, Ellie drives positive change in global population health. She supports ingredient research, outdoor wilderness, youth education, and military health and recovery programs.  

Ellie also supports American Red Cross, having dedicated countless hours to the organization since first volunteering with the Red Cross of Alaska in 2014.  

Ellie’s combination of experience with both investment and philanthropy has inspired families and institutions to make investments in human health.  

Ellie earned her bachelor’s degree in sociology from Harvard University, where she was a varsity ski racer. She earned her master’s degree in agriculture economics from Purdue University and her MBA in agribusiness from Indiana University’s Kelly School of Business, where she was a Tobias Fellow.
