Founder Series: Rene Beltjens on Building Alter Domus

When Rene Beltjens co-founded Alter Domus in 2003, he couldn’t have foreseen that just months later, the global financial crisis would test the business’s foundations. But resiliency quickly became a defining part of Alter Domus’ growth story.

To realize its global ambitions, the company expanded into the U.S. with support from Permira in 2017. By 2019, Alter Domus had reached €321 million in revenue.
