Arcadia Medicine, a San Francisco-based biotech startup developing MDMA-like empathogens, this month closed roughly $9.25 million in seed financing and won FDA clearance to begin human testing of an “safer” alternative to MDMA.
In recent years, MDMA-assisted psychotherapy has made substantial progress toward becoming an FDA-approved treatment for PTSD. In 2017, the FDA granted Breakthrough Therapy Designation to a PTSD program run by MAPS. Two Phase III trials were conducted, and in December 2023 MAPS (now Lykos Therapeutics) filed a New Drug Application for MDMA-assisted psychotherapy, the step before a drug is approved greenlit.
The FDA initially accepted the application but an advisory committee raised concerns about study design, blinding, safety follow-up, and ultimately delayed the decision in lack of sufficient data.
While Lykos is currently addressing the FDA’s concerns, other companies like Arcadia are pushing towards developing MDMA-like compounds foe mental health.
Arcadia’s flagship compound, known as AM-1002 is a patented formulation engineered to deliver MDMA-style therapeutic effects with reportedly fewer stimulant and cardiovascular risks.
On surface, Arcadia’s pipeline is but another push within the broader pipeline for psychedelic medicines. Yet several names stand out as company backers: a small but prominent group of Silicon Valley founders including Sam Altman (OpenAI co-founder and CEO), Coinbase co-founder Fred Ehrsam, and Figma’s Dylan Field are listed among investors.
Arcadia’s official release includes a direct endorsement from Altman himself: “Arcadia’s innovative work in developing a safer form of MDMA is an important step towards a potentially transformative psychiatric treatment.”

What is Altman’s involvement in the company?
Publicly available records and the company’s release identify Altman as an investor and vocal supporter rather than a manager or board member.
The press release contains his endorsing line but does not list a formal operational role.
Secondary reporting from news sources repeats the same facts: local press and sector outlets describe Altman as a backer and, in some pieces, as an early or founding investor, but those outlets trace back to the company announcement for the underlying claim.
Altman has previously described personal psychedelic experiences, saying to Fortune that taking psychedelics ‘significantly changed’ his mindset, helping him overcome anxiety and other mental health issues.
Why Altman’s backing matters to the psychedelics field
Sam Altman’s name carries heavy value for a clinical-stage startup in the forms of capital, messaging, and network. First, Altman’s net worth itself makes additional funding easier to raise because other investors can treat a credible tech founder’s participation as a due-diligence shortcut.
Second, Altman’s public endorsement functions as a reputational wedge: his quote frames Arcadia’s work as “transformative,” which helps normalize the idea of psychedelic therapeutics among skeptical audiences like clinicians, philanthropists, and foundations who may otherwise view MDMA derivatives as high-risk or fringe.
Third, his network. Altman’s ties across AI, venture capital and elite philanthropy can open introductions to strategic partners, CROs (contract research organizations), and subsequent investors, all practical advantages for a company moving from IND to Phase 1.
Tech leaders and psychedelics: a broader pattern
Arcadia’s investor mix is not an isolated case. Over the past several years, high-profile tech figures have repeatedly shown up in psychedelic financing rounds and philanthropic funding. Examples include Peter Thiel’s early backing of Atai Life Sciences and Sergey Brin’s $15 million funding of research into ibogaine-related programs through the company Soneira. These commitments have ranged from direct venture investments to philanthropic grants and have helped bankroll both discovery-stage firms and clinical programs.
Yet the presence of celebrity or tech capital does not substitute for rigorous clinical validation: AM-1002 still faces standard regulatory hurdles before any therapeutic claims can be tested in patient-outcome trials. Arcadia’s IPO, licensing deals, or strategic partnerships will depend on Phase 1 readouts and subsequent efficacy demonstrations, milestones where scientific data, not endorsements, will determine value.
