Lesley Bamberger has an estimated net worth of $1.8 billion, according to Forbes Real-Time Billionaires, Lesley Bamberger profile (figures as of October 20, 2026). That is up from $1.4 billion in 2019.
Lesley Bamberger is a Dutch real estate businessman and the owner and chief executive of Kroonenberg Groep, a private property company. Born in Amsterdam on 3 June 1965, he is the grandson of Jacob Kroonenberg, who founded the company in 1956. His grandfather first worked in textile trading and manufacturing before turning to real estate investment in Amsterdam during the 1960s.
Bamberger did not start at the top. After attending boarding school in Switzerland, he began working at age 17 as a salesperson at The Society Shop in Amsterdam. He then completed internships at international real estate firms and joined Kroonenberg Groep as a commercial associate in 1986. When his grandfather died in 1996, he inherited the company and took over its management.
How Lesley Bamberger makes money
Bamberger's fortune comes from Kroonenberg Groep's property portfolio. The company owns retail, industrial and residential buildings in the Netherlands and the United States. Under his leadership it modernized its commercial holdings and carried out long-term redevelopment projects. One well-known project was the multi-year rebuild of The Bank on Rembrandtplein in Amsterdam, which housed the Ajax Experience Center from 2010 to 2013.
The portfolio has grown into a large business. By 2026, Kroonenberg Groep's properties were valued at more than €3 billion. In 2021 he bought out his cousin's 18.5% stake in the company for €270 million, ending his cousin's ownership in the business. Because the company is private and focused on property, his wealth tends to follow real estate values in the cities where Kroonenberg owns buildings.

Football is his other big passion. He owned Almere City FC for 15 years, and the club reached the Eredivisie for the first time in 2023. He later sold all his shares to Yanmar, a deal completed on 31 October 2025. A lifelong Ajax supporter who joined the club's association in 2009, he became chairman of the AFC Ajax Supervisory Board on 9 March 2026.
