Dr. Paul-Bernhard Kallen

Founding Partner


Paul-Bernhard Kallen does more than just shaping Acton’s values and investment principles – he has come to embody them.

As an investor and entrepreneur himself, he is Acton’s guiding spirit, while his acumen and strategic vision are a touchstone for validating investments.

As a sparring partner in discussions, he is a sharp challenger of assumptions and reliably identifies blind spots.

While his comments are always on point. his experience guarantees reasoned and clear-headed decisions.

As former CEO and now chairman of the Administrative Board at Hubert Burda Media, Paul-Bernhard spends his rare spare time recharging his batteries in the mountains or with his extended family.


“Strength lies in composure.”


McKinsey & Company, CEO/chairman of the board at Hubert Burda Media
