Borneo island

Borneo is the world’s third-largest island located in South East Asia. It holds one of the oldest and the last virgin rainforests left on Earth. Its habitat hosts a great number of fauna and flora that is found only in Borneo. There is only one part of the island that remains largely untouched & unexplored. It is called the Heart of Borneo (HoB) which is also an international conservation agreement initiated to protect a 220,000 km² area. This unique paradise is threatened by humans in the form of illegal logging, palm plantations and forest fires. Borneo has already lost over half its primeval forests, and a third of these disappeared in just the last three decades.

Expedition details

Information covering crucial points that require considerable expertise and effort. I will be subjected to physical and mental challenges and pushed to and beyond my limits.

Camping & survival

Over the last 10 years, I developed high skills and experience in outdoor camping and survival by being exposed to a wide range of demanding conditions and environments.

Physical fitness

Throughout my life, I have engaged in extreme sports such as mountain biking, climbing, and hard trekking. I cycled (bikepacking) around Colombia for 6 months in 2021/2022.

Jungle enviroment

Undergoing and working in the most extreme tropical conditions for an extended period of time. I spent altogether 1 year in the tropical envriroment with 6 months in South East Asia and 6 months in Colombia.


Comfortable meeting the local people and establishing genuine and humble connections with them. I immersed myself and was always accepted with the most remote communities.


Using specific tactical equipment that had been field-tested enabling me to remain safe and productive in such severe surroundings.


Capable of enduring difficult conditions in unfamiliar and unknown territory, even by myself. Traveling to and staying in dangerous regions while still being mission-focused and productive.
