Martijn founded SPACES in 2006, together with Frederique Keuning (MD). They wanted to create a new concept of a serviced work environment for small to medium businesses. With an emphasis on a personalised, homely environment to encourage interaction and collaboration between the different users; the tenants, members of the business club and meeting room guests. Previously Martijn worked as a Commercial and Franchise Director at Regus, and as an International Tax Advisor at Ernst&Young. Spaces has locations in Amsterdam, The Hague, London, New York City and Melbourne. In January 2016, Spaces will open a new location in Rotterdam.
