Building on the power of systems thinking and the potentials of convergent exponential (technology) developments, Karsten supports the scaling of high-impact entrepreneurs, the impact transformation journey of large multinational corporates and the synergies resulting from the cooperation of both. His experiences in building and exploiting the strength of platform business models and the building of related ecosystems adds significant value to his engagements.

Next to his engagement with the Unreasonable Group, he is a mentor at Endeavor and Ashoka and he is a member of the World Economic Forums Expert Group on Accelerating Digital Transformation. Karsten recently joined the board of John Elkingtons Volans and advises futur/io on their programs on moonshots for Europe.

Karsten studied physics, mathematics and computer science in Hamburg, Germany, before he joined Philips Corporate Research to work on Computer Vision, Artificial Intelligence, Neural Networks and Cognitive Sciences in the second half of the 1980s. He received his PhD in Computer Vision from Utrecht University in 1993.
