Executive Board

Thomas Posovatz

Responsible for Investor Relations, Communications, Finance, Accounting and Securities Settlement

After stints at Paul Berwein Börsenmakler AG and its successor, S.G. Warburg & Co., Thomas Posovatz joined forces with three colleagues to found his own firm. Beginning in 1993, Posovatz – a graduate in business administration – has been at the helm of MWB Wertpapierhandelshaus AG, ultimately leading it through its merger with Fairtrade Finance AG in 2008. That merger created one of Germany's largest order book management companies: mwb fairtrade Wertpapierhandelsbank AG. 

Franz Christian Kalischer

Responsible for Securities Trading, Corporates & Markets, HR, Organisation and IT

Kalischer, a graduate in economics and banking, worked for Hamburg-based broker Rolf R. Warnholtz while still completing his studies. In 1995, as the founding partner and managing director of the first German brokerage company, he laid the foundation for what would later become Fairtrade Finance AG. In order to expand its reach beyond northern Germany, the company merged with MWB Wertpapierhandelsbank AG to form mwb fairtrade Wertpapierhandelsbank AG.
