Pieter van Rooyen is part entrepreneur, part scientist, part inventor, but above all an adventurer that revels in exploring and investigating the unusual and often the exotic. He also likes taking pictures of the somewhat strange, the odd, the trivial and the funny. His adventures span his personal and professional life – from adventure travel and adventure sports to studying and working across the globe. He is particularly fond of Africa, the Happy-Sad continent of his birth. He has traveled extensively around the globe hiking, cycling and driving by 4×4 to reach some of the more off-the-beaten-track areas. As an avid mountain biker he has participated in races in the US, Europe, and on occasion even cycled from Cairo, Egypt to Cape Town, South Africa.

In his professional life, adventures are pursued as entrepreneur and inventor where he is devoted to pioneering wireless, multimedia and bio-medical technologies and services. He has more than 20 years of technology development experience, over 10 years of start-up experience and a track record of bringing innovative products and technologies to the market.
