Spinoza App User testimonials
  • Spinoza has given me a safe and professional way to educate myself about psychedelics and how to use them.

    Dirk Dekker
  • As a psychologist, I’ve always been open to all sorts of therapies. I’m very grateful for the opportunity to experiment with psychedelics in a safe environment and explore how they could be useful in a therapeutic way for me.

    Frederique Bicker
  • After my psychedelic experience, I've become more true to myself. I have seen and felt how I am a part of something bigger. Part of nature.

Our organization’s name is a tribute to the philosopher Benedict de Spinoza, who lived and worked in Amsterdam.

In his most influential work, Ethica, he places significant emphasis on the importance of reason and evidence in the pursuit of knowledge. His way of reasoning has been essential to the establishment of modern science.

Like Spinoza, we highly value scientific research and ideally base our assumptions on facts and objective observations.

To perpetually improve our method, programs and ceremonies, we have initiated several research and development programs in collaboration with the Universities of Lisbon and Buenos Aires.

OUR magazine

We’ve compiled a selection of articles about psychedelics – specifically regarding psychedelic truffles containing natural psilocybin. Dive into their history, read about recent scientific findings, and learn to apply them with care and intention.


Who OurteAM

Our team is a close community of nature explorers and medical experts, artists and scientists, meditators and activists who are convinced that the challenges of the future are best addressed by reconnecting with nature and inner exploration.


Chief Executive
Founder | Mentor

Maarten has been teaching meditation and assisting people to make the journey inward for over a decade. With silence, plants and fungi he guides people towards natural wisdom. Maarten has founded Delight Yoga, Wisdom in Business, Return to Sender and The Loft. These initiatives function as a network of organisations united around one sole purpose: inspiring a more natural and conscious way of living. Early in his career, he worked for some large companies which allowed him to think big in terms of organisation and communication. Leading several creative agencies taught him the power of storytelling. Spinoza forms the pinnacle of a personal journey with plant medicine starting in 1999 and has grown into an intelligent network of therapists and scientists united in the mission to experience and experiment with the health potential of natural medicine and nature therapy. Maarten is a proud father to Philip, Alexander and Victoria, and dedicated husband to Anna.

AITO de la RUA

Chief Transformation
Founder | Mentor

From early in his life, Aito has been interested in connecting people to knowledge. In the year 2000, Aito co-created, the first educational platform to connect public schools to the Internet, distributing content to both students and teachers in Argentina. Following the same principle, he co-founded Pure Design – the largest design event in Argentina – with the aim to connect artists and designers with a wider audience. Aito’s life took an adventurous turn as he ventured into the music industry, devoting almost a decade to the management of worldwide renowned artist Shakira.
After exploring several ancient and new practices, Aito joined the Nomade Hotel Group in 2017, which revolves around transformational experiences, music and wellbeing. Studying various ways of transformation combined with his interest in philosophy, he founded Spinoza, which merges his love for psychology, fungi-based therapies and sound as a healing modality.

LIV Stig

Content and
Social Director

Liv loves people. This is why she loves bringing out the best in them. When she started her career in the event industry, she became enchanted by the magic that engulfs people at festivals. She was mesmerized by how open-minded, loving and caring people become once they are relieved of stress and to-do lists, but instead are infused with a feeling of freedom, colourful surroundings and, most importantly; music. Liv was born and raised on a houseboat in the center of Amsterdam. During her travels to India and South America she discovered yoga and has been exploring the spiritual world ever since. At the moment, she also studies to become an Ayurveda Practitioner. Lately she has been focussing on communication and marketing for brands that aim to create positive impact. Increasingly conscious of the briefness of our existence here on Earth and our privileged lives in the West, Liv devotes her energy to projects that aim to help people or the planet – regardless of their scale. Liv is a proud mother to her baby girl Sol.

Saskia has served since then also on supervisory boards in different companies and still does.
