Our TEam

Just like mycelium we operate as a network organisation. Our team is a beautiful 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 self-discovery.


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.

PAUL Berger

Chief Finance and Operations

Paul 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.

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.
