Rini Greenfield

Co-Founder & Managing Partner, Rethink Food

A co-founder of Adaptive Management, a former Tiger Management fund, she helped pioneer the use of big data analysis and visualization to make fundamental long-term investments.

Rini has over a decade of experience investing in technology and consumer companies. She started her career developing a keen understanding of the global semiconductor and capital equipment industry which drove her to develop a strong global supply chain network with a particular focus on Asia. Rini sought out sectors that were at the tipping point of disruption through innovation, investing in wireless products, telecommunications, alternative energy, internet, media, e-commerce, sensor technology, SaaS and others. Her investment scope broadened beyond the U.S. and Asia to the Middle East, Western Europe and Russia. She has extensive relationships with technologists, operators and investors worldwide.

After Adaptive, she expanded her repertoire to private companies. Rini invested for a multi-billion dollar single family office focused on early to growth stage consumer and technology companies with a social impact lens. Investments made during her tenure include one of the world’s largest ride sharing companies which is based in Asia.
