Profile

As the Co-Founder and Managing Partner of Manna Tree, Gabrielle (Ellie) Rubenstein is a passionate investor focused on improving human health. 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 2022, Ellie was appointed to the Alaska Permanent Fund Board of Trustees, where she played a pivotal role over two years, including chairing the Governance Committee and being elected Vice Chair. Her leadership contributed to significant reforms, such as re-establishing incentive compensation for APFC staff, expanding asset allocation, and approving a $100 billion strategic plan.

Beyond her professional endeavors, Ellie is a committed philanthropist through her family office, Mission: Ingredients. She supports organizations that drive positive change in global population health, focusing on ingredient research, outdoor wilderness programs, youth education, and military health and recovery initiatives.

Ellie holds a bachelor’s degree in sociology from Harvard University, where she was a varsity ski racer, an MS in agricultural economics from Purdue University, and an MBA from Indiana University’s Kelley School of Business. Her unique blend of investment and philanthropic experience has inspired families and institutions to invest in human health.
