Management Team Executive board

Stephan Alles Feldhoff
CTO | Founder

The investment specialist Stephan Alles Feldhoff can look back on over 30 years of experience in securities trading and investment banking. One week after the stock market crash in October 1987, he worked as a broker for Esprit Brokerage PLC in Düsseldorf and London. After successfully passing the Series 3 National Commodities Futures (NAFD), Series 7 (General Securities Representative NAFD), Series 63 Uniform Securities Agent (NAFD) and Series 65 Uniform Investment Adviser (NAFD) exams, he joined Mastmann Wells Ltd in London in 1991 as a futures trader and later ED&F MAN. From 2000 he was portfolio manager and head trader at a securities trading bank in Düsseldorf, where he was responsible for investment strategies and trading decisions. In April 2002, he left the company to develop completely new investment strategies and test them with his own capital. The result was SUO TEMPORE (Schweiz) AG.

Anton Zihlmann

Anton Zihlmann, who comes from a merchant's family, took over his father's company in 1988 because he died early. He managed the entertainment company until it was sold in 1990 and then emigrated for 10 years. Since his return in 2000, he has been professionally involved in securities and foreign exchange trading. Mr. Zihlmann has been a member of the Board of Directors since 2009 and CEO of SUO TEMPORE (Schweiz) AG since 2018.
