The brothers Arie and Gerard van der Knijff founded Allsum in 2019. In 2021 a third brother, Sander van der Knijff, joined Allsum as a partner.

With our combined experience in machine construction, control technology, and project management, we support our clients as an independent company from the initial idea all the way through to the realization of their plans.
