The Psychedelic Science Funders Collaborative or PSFC is leading the community of philanthropists funding psychedelic research and supporting psychedelic medicine. PSFC identifies and assesses funding opportunities for its members, provides ongoing support for its funding partners, and facilitates relationships and education about psychedelic research within the philanthropic community. Founded in 2017, PSFC operates as a flexible network to identify and evaluate high-impact funding opportunities in psychedelic medicine, providing advisory support to organizations in the psychedelic field, and foster community support among philanthropists and researchers to amplify the collective impact. The Psychedelic Sciences Funders Collaborative supports research and clinical trials of physician-prescribed psychedelic medicine and patient access to these treatments.
