E-Cep is owned and run by husband-and-wife team Serge Marquie and Sally Wilkinson. They founded the company in 2012 when it became clear the U.S. lacked the benefits of the French en primeur system like the one they had used for years as wine collectors.


Prior to starting E-Cep, Serge worked in the banking industry for more than 20 years building a number of successful businesses, including Deutsche Bank’s groundbreaking Strategic Equity Transactions Group. Most recently, Serge served as joint head of Goldman Sachs’ Latin America Financing Group. He was initially hired by Goldman Sachs as a Partner with responsibility for the firm’s corporate equity derivatives and convertible businesses. Serge holds a Ph.D. in Game Theory from Harvard University, as well as an Engineering degree from École Polytechnique and an M.A. in Econometrics from ENSAE. He is a Fulbright alumnus.


Sally worked as an economist for nearly fifteen years before she co-founded E-Cep. In that time, she served as a U.K. Economist at Deutsche Bank, a European Economist at Union Bank of Switzerland and as Head of Fixed Income Research and Managing Director at Daiwa Securities Europe. Sally also worked in the arena of public policy. In 2004, she was invited to become Economic Advisor to the British Conservative Party. Working alongside the Shadow Chancellor, she penned a number of proposals that were adopted by the incumbent Labour Government or implemented when the Conservative Party took office in 2010. Sally holds a Degree in Economics from Bath University.


The duo lives in Tribeca, New York City.
