Angel Resource Institute

The Angel Resource Institute (ARI) is a 501(c)(3) non-profit organization dedicated to providing education, research, and data regarding the angel investing industry. Originally founded by the Ewing Marion Kauffman Foundation, the institute is widely recognized for its extensive data collection and analysis on the angel investment landscape, most notably through its annual Halo Report. ARI offers a variety of workshops, mentorship programs, and educational resources designed to improve the effectiveness of angel investors and the success rates of early-stage companies. While the organization tracks investment trends within the life sciences and healthcare sectors, it does not develop therapeutics or medical devices itself. It serves as the research and educational arm of the Angel Capital Association (ACA).
