Mission

Zendo Project offers professional harm reduction education to communities and organizations, and provides peer support services at events to help transform difficult psychedelic experiences and other complex emotions into opportunities for learning and growth.

  • Zendo Project Inc. has three core programs:Program 1: Event-Based Harm Reduction ServicesZendo Project provided peer-based psychedelic crisis care at 11 events across 5 states, supporting 473 guests with the assistance of 269 volunteers. Events included major music festivals and conferences such as Psychedelic Science 2025, Burning Man, Phish at Folsom Field, and multiple Red Rocks performances. Through a partnership with Stadium Medical, the organization embedded harm reduction support within existing event medical infrastructure, reducing emergency interventions and improving collaboration between attendees, harm reduction staff, and professional safety teams. This model demonstrates a replicable, cost-effective approach to peer-based crisis care in high-attendance public settings.Program 2: Sitting and Integration Training (SIT)Zendo Project delivered its Sitting and Integration Training (SIT) program to 1,797 students since program launch, with an average participant feedback rating of 8.8 out of 10. The program equips trainees with trauma-attuned, culturally sensitive skills to support individuals navigating non-ordinary states or emotional distress. To expand access, the organization provided 650 scholarships to students who would otherwise be unable to afford participation. SIT serves as the educational foundation for Zendo's broader strategy of building a trained peer support network for crisis response contexts.Program 3: Emergency Psychological Response (EPR) and Zendo Lab Research InitiativeIn 2025, Zendo Project launched two groundbreaking initiatives to expand its impact beyond the festival context. In collaboration with the Cohen Foundation, the organization developed the Emergency Psychological Response (EPR) program for crisis teams, with a pilot launch scheduled for January 2026 and subsequent expansion into healthcare systems, public safety, education, and community settings. Simultaneously, Zendo Lab - the organization's research arm - was established to bring peer support principles into psychedelic science and crisis response research, uniting field-based learning with rigorous data collection. Zendo Lab received national recognition including a presentation at the American Public Health Association (APHA), and will begin building outcome datasets in 2026.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
