What OPEN Foundation does
OPEN Foundation (Stichting O.P.E.N.: Onderzoek naar de Psychedelische Ervaring Nederland) is a Dutch nonprofit organization established in 2007 and headquartered in Haarlem, Netherlands, with a secondary presence in Amsterdam. It is registered as a public benefit organization (ANBI) with Dutch tax authorities and operates with 31 employees. The organization's stated mission is to advance rigorous, interdisciplinary psychedelic research and to support the responsible integration of psychedelics into science, healthcare, and society.
Its portfolio spans four functional pillars: therapist training (the ADEPT advanced program and the Foundations of Psychedelic Therapy entry-level curriculum), conferences (the ICPR — Europe's largest interdisciplinary psychedelic research conference, with the 7th edition scheduled June 4–6, 2026 in Haarlem), a community and content platform (the OPEN Community/Circle with General, Plus, and Pro membership tiers), and research and policy initiatives (notably the PsyPal program — the first European grant funding clinical research into psilocybin-assisted therapy in palliative care — and the Working Group Psychedelics GGZ and Indegeest research networks).
The business model is a hybrid of recurring membership subscriptions (Plus at €9.99/month or €100/year, Pro at €20/month or €200/year, with a General free tier), donations, conference and workshop ticket revenue, and training program fees, supported by EU and institutional grants. Its go-to-market is community-led and event-driven: a bi-weekly newsletter reaching 10,000+ subscribers, monthly online events, journal clubs, peer perspectives, the annual ICPR conference, and strategic partnerships with organizations such as Beckley Foundation, MAPS, Heffter Research Institute, MIND Foundation, and University Medical Center Groningen. Customers are primarily individual therapists, researchers, students, policymakers, and field-adjacent professionals; no enterprise anchor customers are disclosed.

OPEN Foundation competitors and assessment
Company assessmentBroad incumbents
- Compass Pathways: Public, well-capitalized (NASDAQ: CMPS) commercial developer of psilocybin therapy with proprietary COMP360 clinical program and a parallel therapist training infrastructure. A broader, well-funded incumbent that overlaps with OPEN on clinician training and research-dissemination domains while operating at much larger commercial scale.
Direct peers
- ICEERS (International Center for Ethnobotanical Education, Research and Service): Spain-based nonprofit supporting ethnobotanical research, education, and advocacy around plant medicines. Mirrors OPEN's nonprofit operating model, interdisciplinary scope, and European footprint; an OPEN partner operating in adjacent therapeutic and policy domains.
- Chacruna Institute: US-based nonprofit providing education on psychedelic plants and traditions, hosting conversations, and publishing on cultural/legal frameworks. Comparable to OPEN's interdisciplinary community-building, education, and public-discourse convening function.
- Beckley Foundation: UK-based foundation funding psychedelic research, hosting psychedelic policy programs, and convening scientific symposia. Shares OPEN's foundation model, research facilitation focus, and European policy engagement — listed as a major OPEN partner and a parallel competitor for funder mindshare.
- MAPS (Multidisciplinary Association for Psychedelic Studies): US-based nonprofit leading MDMA-assisted therapy research, therapist training (MDMA-TRAINING program), and global psychedelic policy advocacy. Closest analog to OPEN globally with an overlapping mission in research facilitation, clinician education, and conference/convening.
- Usona Institute: US nonprofit sponsoring psilocybin clinical research and open-science initiatives. Closely comparable to OPEN's PsyPal role — a foundation sponsoring clinical psychedelic research and disseminating findings — with overlapping scientific and policy objectives.
- MIND Foundation: German nonprofit advancing psychedelic science and therapy across Europe via training programs, conferences, and research. Directly comparable to OPEN's therapist training (MIND's "psychedelic therapy training"), community, and research intermediary role — competing for the same European professional audience.
- Heffter Research Institute: US nonprofit funding scientific research on psychedelics (notably psilocybin). Comparable mission and operating model to OPEN's research-facilitation arm; both channel philanthropic capital into academic psychedelic research and convene scientific communities.
- Fluence Training: Private organization providing continuing-education training for psychedelic therapists and clinicians (e.g., psychedelic integration, ketamine-assisted psychotherapy). Directly comparable to OPEN's ADEPT/Foundations/KAP training offerings — competing for the same clinician learner pool, listed as an OPEN channel partner.
Emerging players
- Johns Hopkins Center for Psychedelic and Consciousness Research: Academic research center conducting rigorous psychedelic clinical trials and publishing landmark studies. Comparable to OPEN in research facilitation and convening, but anchored inside a top-tier US university rather than operating as an independent nonprofit foundation; partial overlap with OPEN's research and training community.
