The Mandaat team
Mandaat’s Managing Partners
Diederik van den Biggelaar and Janco Duvekot know what it’s like to break a sweat. Diederik explains. ‘A personal approach is self-evident to us, precisely because we have years of experience, including as entrepreneurs. We know what responsibility means, the strains upon a businessperson. So we can quickly sense what our client is looking for.’
Diederik began his entrepreneurial career when he was still at university, as one of the founders of renowned student disco Dansen bij Jansen in Amsterdam. He then moved on to the international world of business, working at Heineken for an extended period of time. He worked in the bars & hotels branch as well as the international branch. He left Heineken as the chief export manager for Europe and Japan.
After Heineken, Diederik worked at Samas as group executive, GM at De Boer Temporary Structures, owner-manager of Perfecta, founding partner of iKi Beer, and as senior partner at Custom Management. He has been one of the owners of Mandaat for over 9 years now.

Janco comes from a Sales and Marketing background, with experience at Heineken. He started out there after studying business economics in Rotterdam. At Heineken, he acted as commercial executive at Vrumona, the largest supplier of fizzy drinks in the Netherlands. He moved on as an independent manager in the Business Development arena.
