Joost Sweep studied law at Erasmus University in Rotterdam, specialising in Business and Private Law. After university, Joost launched his career at Vroom & Van den Heuvel, an Executive search agency specialised in higher management positions. Here, he grew to a Senior Advisor level.
His interest in commercial real estate led him to apply for a position with Jones Lang LaSalle (JLL) in 2001. After 3 years, he became managing director of the Rotterdam office (renting/leasing, buying/selling commercial property). Joost was a member of the Dutch management team and regularly travelled abroad as European Director to help shape JLL’s international strategy. In 2011, he made the switch to the Capital Markets department in Amsterdam, where he was involved in the purchase and sale of commercial real estate (offices, industrial buildings and residential) in the Netherlands. At the end of 2015, Joost was asked to lead the Corporate Tenant Representation team of JLL (leasing, renegotiating and sale & lease back transactions for end users of real estate).
With more than 17 years of experience in commercial real estate in the Netherlands, Joost decided to start his own company and founded Marble Real Estate together with Kristian van Eijkelenburg.
Kristian van Eijkelenburg studied Urban Planning at the Hogeschool Utrecht, specialising in urban planning, followed by a bachelor’s in Social Geography and a master’s in Real Estate Studies at the University of Groningen.
He started his career in early 2008, at ING Real Estate Development as a junior project developer and account manager letting offices. In 2009, Kristian made the switch to BMC, a management and consultancy firm, where he focused on healthcare real estate and area development.
With this broad background, Kristian started to focus on commercial real estate advice in mid-2010, and started working for Jones Lang LaSalle (JLL). He worked there for 2.5 years as a real estate consultant in The Hague region with a focus on leasing, rental and sales of commercial real estate and redevelopment projects. In 2013, he switched internally to the Corporate Tenant Representation Team. In this position he advised occupiers of real estate on leasing, renegotiation, sale & lease back transactions and redevelopment assignments. As Senior Advisor and Associate Director, Kristian has been responsible within this team for the regions of The Hague (3.5 years) and then Central, North and East Netherlands (2 years).
Kristian set up JLL’s healthcare real estate division on his own initiative in 2018 and was ultimately responsible for this discipline. The focus was primarily on leasing, selling, purchasing and redevelopment assignments for healthcare institutions.
In mid-2019 and with more than 11 years of experience in commercial real estate, Kristian founded Marble Real Estate together with Joost Sweep.
