Our Story

Founded by a data scientist and a seasoned political strategist

Mike Greenfield and Pat Reilly, cofounders of Change Research
Change Research was founded in the wake of the 2016 election, when the limitations of traditional polling had never been more apparent. Cofounders Mike Greenfield, an entrepreneur and analytics leader who began his career as the first data scientist at PayPal and LinkedIn, and Pat Reilly, an experienced political strategist, saw an opportunity to build something better: a faster, more accurate approach to political research that could serve forward-looking campaigns, caucuses, political committees, and advocacy organizations.
Launched in 2017 and powered by innovative approaches like Dynamic Online Sampling, Change Research was the only pollster to show Lori Lightfoot winning in Chicago, Kendra Horn winning in Oklahoma, and the first to see JD Scholten close to a win in Iowa — earning an early reputation as the "hipsters of the polling world."
The company continues to push the boundaries of what political research can do — launching AI-powered tools like Magnify AI, earning multiple Reed Awards and a Netroots Nation recognition, and delivering on the original vision: deeper, faster, more accurate research.
