The Third Wave is a new era of psychedelic use.
It is an era of psychedelic use defined by practical, measured use for specific purposes. It is an era, not for ‘dropping-out’ and rebelling against society, but for integrating psychedelics into our mainstream culture. It is an era, not to fear psychedelics for their possible negative repercussions, but to embrace psychedelics for their tremendous upside.



Let's Go on a Journey Together

There is one modality that high-performing individuals have used - often in secret - to reach peak-performance levels in their professional work and personal lives.

This modality leverages non-ordinary methods to reach elevated states of consciousness that accelerate personal development, catalyze creative breakthroughs, and unlock leadership potential.

Although undiscovered by many, it will only be a matter of time before the word gets out about this unique and powerful method, meaning you will be one of the first to responsibly integrate this experience for increasing your competence, developing autonomy, and expanding your personal boundaries.

What we’re talking about, of course, is the psychedelic experience.

Steve Jobs called it one of the most profound experiences of his life.

Tim Ferriss, best-selling author and tech entrepreneur, has said that all the billionaires he knows, with few exceptions, take this journey on a regular basis.

And Plato formed his foundational beliefs by utilizing the psychedelic experience, thus setting the groundwork for all of Western philosophy.

And now we’re taking this secret and offering it to a few select individuals in our groundbreaking ‘Synthesis’ program.



Safe, Legal, and Structured Framework For Personal and Professional Breakthroughs

Recent findings focused on understanding the utility of psychedelics for creativity show us why these useful tools work for innovative professional problem-solving.

Simplified, we use two main ways of thinking when working on professional problems: convergent and divergent thinking.

Convergent thinking, which consists of slow methodical improvements, is great for linear solutions and productivity. Substances like caffeine, adderall, and modafinil facilitate convergent thinking. Because this type of information processing is valued in our workplace, these means of enhancement are most commonly used by people in a professional workspace.

However, for breakthrough solutions initiated by divergent thinking, different conditions are warranted. Divergent thinking is more disruptive and free flowing, leaves room for ambiguity, and draws on our imaginative capabilities to provide us with sudden paradigmatic shifts.

In 1966 at the International Foundation for Advanced Study, a privately funded facility dedicated to psychedelic drug research, Dr. James Fadiman and his team evaluated whether the use of psychedelic substances helped participants come up with new insights, and whether such solutions were seen as valid beyond the psychedelic experience, both to the participants and their professional peers.

In total 27 professionals signed up for the experiment, including engineers, physicists, mathematicians, architects, designers, and artists. Prior to signing up, the participants had worked weeks or months on their chosen problems wIthout obtaining a satisfactory solution.

The moderate dose psychedelic experience helped participants to unlock their seemingly intractable problems. The 27 participants came up with widely embraced original innovations, including a mathematical theorem for NOR gate circuits, a conceptual model of a photon, a linear electron accelerator beam-steering device, a new design for the vibratory microtome, a technical improvement of the magnetic tape recorder, blueprints for a private residency and an arts-and-crafts shopping plaza, and a space probe experiment designed to measure solar properties.

This isn’t the only research we have, however.

In April 2016, David Nutt’s team at Imperial College in London did fMRI scans of an individual under the influence of 75 micrograms of LSD.

Here is an interpretation of the brain imaging scan:

                                                                       Interpretation of Brain Imaging Scan in two situations: with no psychedelic and under the influence of 75 micrograms of LSD

                                                                      Interpretation of Brain Imaging Scan in two situations: with no psychedelic and under the influence of 75 micrograms of LSD


When under the influence of a moderate psychedelic dose, the brain has heightened levels of cross-communication.

Parts of the brain which are normally segregated, start to communicate with one another, representative of the increase in divergent thinking ability.

Other modalities, like meditation for example, facilitate similar states of consciousness. However, there is no modality as consistent and powerful as psychedelic substances to strip away standard frames of references to allow for the generating of profound, innovative insights.

But psychedelics aren’t only for creatively solving technical problems. They’re also an excellent tool to facilitate personal transformations in alignment with next generation leadership development.


The Relationship Between Psychedelics and Leadership Development

According to the McKinsey Global Institute, the number one private-sector think tank in the world, the biggest requirement for leaders in the decentralized work environment of the 21st century is adaptability.

The working world is becoming increasingly complex and chaotic. To be heard in the noise of the 21st century requires generating and executing on unique, impactful ideas that are responsive to the needs of people. Leaders who understand how to build an adaptable, responsive vision that draws on the strengths of team members (rather than coercing them into a rigid framework) will be in high-demand.

Because psychedelics pharmacologically improve adaptability, they are excellent tools in training an adaptable leadership style, which will be increasingly useful in decentralized work environments.

Which brings us full circle.

By attending our Synthesis program you will have the opportunity to:

  1. Catalyze breakthroughs in your own creative thinking for solving high-level professional problems

  2. Facilitate your own leadership development to be more effective in a 21st century workplace environment

  3. Have a safe, legal, and guided psychedelic experience with the care and support of leading experts in the field

In working with psychedelics to facilitate creative thinking and high-level adaptability, we will provide the training space to cultivate a new state of mind that will serve you in innovative problem solving and/or visionary leadership.

Consider Synthesis your first step on this new journey.

A journey which trains your new state of mind to harness altered states of consciousness induced by psychedelics to reach your peak of creative, visionary thinking while facilitating your own personal journey of self-actualization.


We are creating next generation leaders and problem solvers who use psychedelics to catalyze personal and professional transformation.

Nothing like Synthesis has been offered before. In short, we’re taking the ‘secrets’ of high-performing leaders and experts that have remained underground due to cultural stigma and making them available to you.

In committing to this experience, you will be a pioneer in your own right, joining a specially curated list of attendees who are contributing to the next evolution of humanity in a significant way.

By the end of your experience at SYNTHESIS, you will have come to recognize your own agency in using psychedelic tools in a conducive context to unleash your imaginative possibilities in a way that aligns with your professional interests.

SYNTHESIS Inner Circle

At SYNTHESIS, we have gone the extra mile to ensure your entire experience is curated to facilitate inner breakthroughs so you can take that next leap in your own life.

That’s why we’re also giving you lifetime access to the SYNTHESIS ‘Inner Circle’ as part of your retreat commitment. This will be an ongoing group that will provide professional support and networking as you continue the process of your own personal development in utilizing psychedelics to grow and mature.  

In fact, we believe our SYNTHESIS ‘Inner Circle’ is the most valuable aspect of committing to this retreat. In joining us for a 3-day Synthesis retreat, you will meet and deeply connect with 7 other ambitious, talented, and inspiring participants who will become valuable contacts in your professional pursuits. You will also get access to all other alumni of SYNTHESIS.

Further, if the fit is right, Paul and Martijn will be happy to facilitate connections for you within their own professional network of executives, change-makers, coaches, and founders to amplify your own personal and professional development.

Who are we?

We utilize psychedelics in moderate and microdoses for professional breakthroughs and personal development.



The Workshop

Exclusive 3-Day Psychedelic Retreat in Amsterdam

We are offering an exclusive 3-day retreat in Amsterdam for ambitious, motivated, and determined professionals who want to utilize moderate doses of psychedelics to catalyze creative breakthroughs and facilitate leadership development.

We and our experienced team of professionals have personally taken psychedelics hundreds of times, facilitating experiences for dozens of other people in the process.

However, this is the first time ever a legal opportunity exists for the public to take psychedelics in a safe, intentional and expert-guided setting to solve problems, enhance creativity, and facilitate leadership development.

We will control for the following six conditions that play an essential role in every psychedelic experience:

  • Set: the mental attitude of a would-be psychedelic voyager

  • Setting: the surroundings in which a psychedelic substance is ingested

  • Guide: a person experienced with non-ordinary states of consciousness who helps to mitigate challenges and channel insights

  • Substance: the type and quantity of psychedelic agent

  • Session: the entirety of a psychedelic trip, including all activities and rituals

  • Situation: the environment, people, and culture from which a person comes to a session and returns afterward

When these vectors are not controlled, and psychedelics are not done in a safe, supportive, and structured setting, many of the benefits will not be experienced. Instead, an individual can easily become overwhelmed with all the unfamiliar sensory input, which can consequently lead to paranoia and confusion.

Because of the power of psychedelics, and the strong influence of others on your experience, we will limit the workshop to eight carefully selected professionals. This retreat is not open to everyone, and an application process for the 3-day retreat is mandatory for each individual.

Price: €1350. 

Dates available:

  • April 15-17
  • April 18-20 (1 spot left)
  • April 20-22 (sold out)

Interested participants are limited to a maximum of two workshops

If you're interested in doing more than one workshop, please indicate this in your application.

(All expenses are covered except travel costs to and from Amsterdam - this workshop includes accommodation and meals)
