As early as during his study of International Economics at the University of Amsterdam, Jacob was already active in international trade. After his graduation, Jacob soon moved to New York where he worked as a trade representative for Netherlands at the United Nations, and later on as Deputy Head of the economic section of the Consulate General of Netherlands in New York.
In 2002, Jacob started his own consulting company in New York. With ‘ New Amsterdam Trade & Consultancy ‘ Jacob still assists Governments and businesses when positioning for procurement at the UN. In 2010, Jacob founded (TABS Inc.) Trans Atlantic Business Services, with the goal to take care of the “back office” activities for European companies involved in the start-up of their American entity. This will give the parent company the opportunity to completely focus on sales and marketing or business development activities in the the US, instead of administrative and bureaucratic matters. TABS meanwhile has proudly assisted more than 150 Dutch companies.
