Comparing Inner Shift Institute and Kiyumí Retreats:
Which Approach Fits Your Needs?
If you are considering a psilocybin retreat, understanding the structure, philosophy, and level of support offered by different providers is essential.
Two organizations you may come across are Inner Shift Institute and Kiyumí Retreats. Both offer guided psilocybin experiences designed to support meaningful inner exploration within a structured environment.
However, their approaches differ in how the experience is designed, how support is delivered, and what each retreat is ultimately optimized for.
Understanding these differences can help you choose the setting that best aligns with your intentions.
Preparation and Integration: A Shared Foundation
Before exploring the differences, it’s helpful to recognize where both programs align.
Both Inner Shift Institute and Kiyumí Retreats include preparation before the retreat and integration afterward, acknowledging that the psilocybin experience is part of a broader process rather than a standalone event.
At Kiyumí Retreats, preparation is relatively simple and accessible. Participants typically attend a single online meeting prior to the retreat and receive a preparation and integration kit. Following the experience, participants join one online integration session and engage in group-based integration practices throughout the retreat itself, including movement sessions and workshops.
Inner Shift Institute also includes preparation and integration, but with a more layered and individualized approach. Participants typically receive over six hours of preparation workshops alongside one-on-one sessions tailored to their emotional patterns and intentions. Integration includes structured workshops (approximately eight hours or more), individual sessions, and ongoing follow-up support designed to help translate insights into daily life.
While both include these phases, the level of depth, personalization, and continuity differs significantly.
The Core Difference: Therapeutic Processing vs Holistic Group Experience
The most significant distinction between the two organizations lies in their underlying methodology.
At Inner Shift Institute, the experience is grounded in a trauma-informed therapeutic framework. The Inner Shift Method integrates psychological and somatic practices, including inner child work, parts work (IFS), and nervous system regulation. The focus is on working directly with emotional patterns and underlying experiences in a structured and supported way.
During ceremonies, facilitators may offer active support when needed, helping participants navigate emotional material while maintaining stability and a sense of containment.
Kiyumí Retreats, by contrast, offers a holistic and embodied group experience. Their retreats combine psilocybin ceremonies with practices such as:
- Yoga
- Breathwork
- Movement
- Creative workshops
The emphasis is on presence, somatic awareness, and connection within a shared group environment, rather than structured therapeutic processing.
Retreat Format and Structure
Another key difference lies in how each program is structured and experienced.
Kiyumí Retreats follows a standardized group format, typically offering a six-day retreat that includes two psilocybin journeys. The schedule is shared across participants, with a strong emphasis on group cohesion and collective experience.
Inner Shift Institute offers a more flexible model. Retreats can range from one-day private sessions to multi-day immersive experiences, including six-day group retreats. Participants can choose between private, couples, or small-group formats, with pacing adapted to individual needs and emotional readiness.
This difference can significantly shape the experience. Some participants thrive in a shared group rhythm, while others benefit from a more personalized and adaptable structure.
Emotional Safety and Trauma-Informed Care
A defining feature of Inner Shift Institute is its explicit focus on trauma-informed care.
Emotional safety is central to every phase of the process, from preparation through to integration. The structure is designed to support participants in navigating emotional experiences with appropriate guidance and regulation.
This approach can be especially supportive for individuals working with:
- anxiety or depression
- unresolved emotional experiences
- complex relational patterns
Kiyumí Retreats incorporates elements of trauma awareness through a compassionate facilitation style, and its team includes practitioners from psychotherapeutic and somatic backgrounds. However, trauma-informed care is not positioned as a central, structured framework guiding the entire process.
Facilitation Style and Support
Support during the retreat also differs in both style and depth.
At Inner Shift Institute, ceremonies are guided by psychologists, psychotherapists, and facilitators trained in trauma-informed care, somatic therapy, and emotional regulation. Their role includes actively supporting participants when needed, helping maintain stability and containment throughout the experience.
At Kiyumí Retreats, facilitators include psychotherapists, somatic practitioners, and creative or movement-based therapists. Their role is to support the group experience through a combination of modalities such as yoga, breathwork, and artistic expression.
Facilitator-to-participant ratios also differ. Inner Shift operates with higher support ratios, including one-on-one support in private formats and approximately 1 facilitator for every 2–4 participants in group settings. Kiyumí Retreats typically operates with approximately 1 facilitator for every 4 participants, within group sizes that can reach around 16 participants.
Both provide guided support, but the level of individualized attention and therapeutic involvement differs.
Practical Considerations: Accessibility and Experience Design
Practical elements can also influence which retreat feels like the right fit.
Inner Shift Institute offers highly customizable retreat formats, including private and couples retreats, as well as small group settings. Programs are available in multiple locations, including the Netherlands, Portugal, and Mexico.
Kiyumí Retreats focuses on a standardized group experience in the Netherlands, with a fixed six-day structure.
Medication policies also differ. Inner Shift may accommodate participants taking SSRIs when appropriate following careful screening and informed discussion, while Kiyumí Retreats does not accept participants currently taking antidepressants due to potential interaction risks.
Inner Shift Institute also explicitly supports neurodivergent participants, adapting preparation and retreat environments to meet diverse needs. Kiyumí Retreats does not position neurodiversity support as a central focus in its programming.
Community and integration structures also vary. Inner Shift offers ongoing integration support and continued connection after the retreat, while Kiyumí emphasizes group-based integration during and shortly after the retreat, without a clearly defined long-term alumni structure.

Key Differentiators: What Inner Shift Institute Offers
Several features distinguish Inner Shift Institute’s approach:
- A trauma-informed foundation: Every step of the process is built around emotional safety and structured support.
- Specialized support for neurodivergence: Our approach is specifically designed for people with ADHD, autism, giftedness, and complex emotional patterns.
- Flexible formats: We offer private sessions, couples work, and small groups instead of sticking to a rigid 6-day group schedule.
- Healing deep-seated patterns: We use intense preparation and structured integration to help you actually resolve old habits, not just talk about them.
- Built-in nervous system support: Staying grounded and regulated is a core part of our method, not just an extra activity.
- More location options: You can work with us in Portugal and Mexico (where legal or decriminalized) as well as the Netherlands.
- SSRIs accommodation when appropriate: While we still recommend tapering off SSRIs, we generally allow people to participate if they choose to accept the risks after we walk them through the information.
If you are looking for a more personalized, therapeutically grounded approach that focuses on emotional pattern work and structured integration, Inner Shift Institute offers a level of depth and flexibility that differs from the Kiyumí model.
