About Mike Greenfield

Mike Greenfield is the Co-Founder and CEO of Change Research, a data-driven research firm, and previously served as the first data scientist at PayPal and LinkedIn before founding four companies including TeamRankings. As an angel investor with 24 recorded investments, he focuses on pre-seed and seed stages in sectors such as parenting, local services, analytics, and AI, primarily within the San Francisco Bay Area. His typical check sizes vary across funding rounds, and he frequently co-invests alongside partners like James Currier and Jeff Clavier rather than acting solely as a lead. Notable portfolio companies include Literably, CareGuide, Babylist, and Fieldbook, which reflect his interest in data-enabled solutions for families and education. Greenfield distinguishes himself as a “data geek” and entrepreneur who leverages his statistical background to evaluate startups, though no specific public writing or distinctive investment manifesto is cited in available sources.
