Senior Investment Consultant

We are at your disposal as an independent and competent authority for economic and investment questions.

The consulting firm Wellershoff & Partners Ltd. was founded in 2009 by the former chief economist of UBS, Prof. Dr. Klaus W. Wellershoff. To ensure a long-term focus and succession solution, the employees and all processes, tools and applications were separated from Wellershoff & Partners Ltd. in 2020 and integrated into the new company WPuls AG. Klaus Wellershoff is Chairman of the Board of Directors of WPuls AG. WPuls AG stands for what Wellershoff & Partners has already distinguished itself for: Independence, data-based expertise, holistic world view, proven solutions.
