City-based funders focused on education are eager to invest in technology-based initiatives to address education’s most complex problems. However, many funders are struggling to figure out how to most effectively and expeditiously realize technology’s potential in schools. This white paper—published by the organization now known as Education Cities— identifies and catalogs the core components of education technology markets that city-based funders might support, and how they might support them. Interviews with funders and education technology experts yielded thoughtful observations about options for city-based funders in two categories: intervening directly in education technology markets to fund creators or users of cutting-edge technologies, and catalyzing activity or funding, to educate the field or create conditions favorable to the creators and users of education technology.
