Curated Psychedelic Experiences

Maarten van HuijsteeChief 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 RuaChief Transformation
Founder | Mentor
From early in his life, Aito has been interested in connecting people to knowledge. In the year 2000, Aito co-created ‪Educ.ar, 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.
Paul BergerChief Finance and OperationsPaul loves numbers. Not because of their looks but because he can see through them. Numbers have meaning and Paul aims to make them mean something positive out in the real world. Whether he’s out tour-skiing, mountain biking or langlaufing, Paul infuses anything around him with positive energy. After studying Business Economics, and a career as an investment director at an international private equity firm, Paul decided to move into healthcare, taking on the role of CFO at a Dutch healthcare platform. Besides work, he’s been active in a number of initiatives that aim for positive social impact, both in healthcare and sustainability. He’s a proud father of three; daughter Nanna and sons Tom and Cas, and happily married to Alexandra. Paul believes that the best decisions are not taken by cognitive notions, but by a deeper intuitive intelligence.

Ben FeiertagChief Programming

For many years he has been exploring his inner world with ancient practices and these experiences have helped him to develop a keen sense for people and their innate capabilities. At Spinoza, Ben is responsible for the strategic development of our programs and educational platform. Ben’s career led him from the financial political world to the domain of leadership and personal development.

Liv StigContent 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.
Stacey GriffinMusic and
Sound Director
Music is what moves Stacey. It defines the rhythm of her heartbeat. Stacey loves music – and we think it’s safe to say the adoration is mutual. The meaning of music goes beyond the grasp of words. Stacey sees sound in different dimensions and knows how to administer it for healing purposes. Stacey is a sound therapist, artist and advocate for sound healing. As the founder of Shift Meditation, she creates immersive sound meditation experiences, and is also part of the music group End of Time.
With twenty years of experience launching and marketing brands globally in the industries of fashion, music and wellness, Stacey has lived across the globe; from Toronto to Tokyo and from Los Angeles to New York. She currently calls Amsterdam home, where she lives with her two children Lola and Jack, and her partner Peter. Stacey likes to spend her spare time on the beach and has always had a preference for Detroit techno and reggae.
Jons JanssensDigital and
Technology Director
Jons likes to start, build and change things - always with digital product development as his preferred tool to create long term value. Jons is most passionate about putting the economic engine to work as a force for good. This is why he has served in various leadership and founder roles across several business innovations. One of his talents consists of bridging the gap between value opportunities and technology implementation. Jons is here to build the rails on which an organisation delivers value by putting the customer journey at the heart of the operation. This applies to the technical architecture, interface design as well as team organisation.
Bram van LeeuwenContent
Writer
Bram likes creating things. Whether it’s in writing, drawing, short film or brand building, Bram addresses complex issues in a lighthearted and unconventional way. Bram’s worldview consists of a blend of criticism, absurdism and altruism. He has been fortunate enough to wield strict selection standards regarding the clients he works with from early on in his career. Bram has been building brands with a conscience in terms of sustainability and social responsibility for over a decade and has been experimenting with psychedelic substances for an equal amount of time. He derives his inspiration from intuitive insights, creating deeper connections between people and ideas. Bram explores philosophy with a humorous approach and believes an open mind is a human being’s greatest asset. He can turn a blank sheet of paper into colourful and alive brands and organizations with a clear and comprehensible vision. Bram lives in the centre of Amsterdam and enjoys his early morning kayaking trips on the canals.
Aliet RogaarBody worker | Therapist
Cranial-sacral | Yoga
Aliet is a life-long yogi, dancer, nature lover, gardener and cook. She lives in a small green oasis in the center of Amsterdam and spends as much time as possible gardening. While teaching leadership classes to youth in New York City during the 90’s, she was confronted with the complete lack of healthy nutrition and nature many people suffered from.
Aliet realized that we only get a fair chance at pursuing our dreams and goals when we learn how to nourish and move our bodies according to nature. Unexplained pains as a teenager acquainted her with different disciplines of medicine and the healing arts. Yoga, dance and movement helped her to overcome her pains and awakened her passion for natural ways of healing and bringing body and mind together. In 2000 she opened a private practice for shiatsu, and over the years she has combined this with cranial-sacral therapy and art therapy. As Aliet never finishes learning, she currently studies biodynamic farming and has started a beautiful permaculture vegetable garden. She loves to spend time with her family and friends and enjoys the here and now.
Saskia van WalsumAdvisor | Shareholder
STAK Board
Saskia has since a long time been involved in all kinds of organizations and in mobilizing people. After twenty years of experience in commercial and financial management positions and having worked in global HR and CEO roles at multinational Heineken and Royal Friesland Campina, Saskia decided to change track. She (co-) founded an independent investment fund in entrepreneurial PE, which she led over the course of twelve years. During that period, she simultaneously studied the practice of energy fields for seven years, to understand and read people at deeper levels of energy and consciousness. This has influenced her profoundly. The last fifteen years, she has also been active as a coach and counselor for executives and teams; helping them to open up to their core values driving their behavior, and supporting leaders to absorb inputs and learnings into new practice and flourish. Saskia has served since then also on supervisory boards in different companies and still does. She keeps us with our feet on the ground and advises Spinoza on how to build a purpose-led and sustainable company. Saskia believes that being part of nature and breathing it in fully, helps us to open up and tap into our own intuitive wisdom. We can trust and listen to this open space, as it will guide us.
Sasha HauptmannAdvisor | Shareholder
Plant Advocate
Sasha was born in Vienna, but moved to Argentina to study agriculture and alternative sustainable farming. Sasha was amongst the founders of an organic ranch and hydroponics in Argentina, and a CBD farm in Uruguay, using hemp as a raw material for different medical possibilities. Sasha is also active in the plant-based pharmaceutical industry, as he is part of the shareholder group and strategic team at Echo Pharmaceuticals based at the University of Leiden.
Spinoza is a chance for Sasha to bring natural and plant based medicine to people around the world.
Sasha is convinced that it’s time to start preventing health issues - not merely responding to their symptoms.

Manifesto

Deus
sive
natu
ra.

Ask your local forester what it is that keeps trees generally healthy, and he or she will answer ‘mycelium’. Fungi. They form the cerebral network of the Earth. Think of it like a natural analogue ancestor of the world wide web, if you will.


We believe that psychedelic fungi and flora can have the beneficial effect of stripping down the dogma of how we think reality is supposed to behave. We become humble. We start to acknowledge that we cannot blindly trust all of our current judgements and may need to revise some of our habits.


We surrender to a space of openness - where insights and ideas can flow freely, even beyond our control. We observe them. We are grateful for them, for they are not our own, and certainly not ours to keep.


We learn. We become less fearful – of ourselves, of our fears, of the enormity of the Universe and its infinite possibilities – until only one possibility remains, and that is taking care of ourselves; the very nature we live in.


We believe that fungi and flora can function as a guide of the universal consciousness of nature. The logical and harmonious patterns that are present in the architecture of everything alive. In other words, the driving force of life itself.

God is Nature.
Deus sive natura.

How

Transformationalexperiences

Rememberyou arethemedicine.

We are a collective of bionauts.
We explore inner worlds with fungi and flora. We discover outer worlds with friends and fellows. We guide people through fields of joy and support one another in moments of need.

We are a human growth company.
It’s our mission to transform people in connection with nature. We teach people how to transform the mind and connect with the body in order to access a deeper intuitive intelligence.

We are convinced that the benefits of psychedelics and the longevity of their effectiveness is highly increased by embedding them in nature and supporting them with meditative practices and music experiences.

Remember, you are the medicine.

What

Curatedpsychedelicexperiences

With our network of specialists and scientists, artists and experts, we offer legal and safe truffles containing natural psilocybin combined with meditative practices and immersive music experiences.

With the controlled cultivation of fungi in our Farmlab, we are developing Mycelium Spinoza; an affordable and effective organic mycelium containing natural psilocybin to support our transformational programs and experiences.
