Synthesis Institute Resumes Bookings After 2023 Financial Collapse

Synthesis Institute, a Netherlands-based legal psilocybin-truffle retreat operator, underwent a publicly reported financial collapse in March 2023. As of our research for this directory, it appears to have resumed operating, with 2026 retreat dates live on its booking system.

Background

The 2023 collapse was reported by TechCrunch at the time. We have not independently confirmed the current corporate entity, ownership structure, or financial standing behind the retreats currently being booked under the Synthesis Institute name.

Why we’re flagging this rather than omitting it

We’ve chosen to include Synthesis Institute in this directory because it’s a real, apparently currently-operating retreat option — but we think readers deserve to know about the 2023 history before booking, which is why it’s called out both here and directly on the listing itself, rather than left for readers to discover independently.
