The way we work

It’s always difficult to talk about yourself. That’s why we’d like to quote some interim managers and some of our clients.

‘The guys at Mandaat are straight shooters, they don’t horse around. They are clear and quickly bring us candidates to our satisfaction.’

‘Their own knowledge and experience of SMEs, startups, private equity and big corporations allows them to join us in finding the right management solution, no holds barred. They’re real entrepreneurs!’

Our History

Mandaat was founded in 2000 as a subsidiary of Custom Management.

It has been an independent bureau since 2009, led by the two former partners of Custom Management, Jeroen Nuesink and Diederik van den Biggelaar.

Our focus was first and foremost on restructuring and helping businesses get out of heavy weather. Since 2012, we have found an additional unique proposition: we find managers who can run foreign subsidiaries of Dutch and other internationally active companies.

Janco Duvekot joined us in 2017 as a shareholding partner, when Jeroen stepped down.

In October 2020, Mandaat became part of JBR and has since been located at Het Rond 6a in Zeist, after which Jan Kalisvaart joined as the new Managing Partner in April 2021. Diederik van den Biggelaar and Janco Duvekot will remain involved as Associate Partner
