Descheemaeker recently served as CFO at Delhaize Group, a €20bn international food retailer, before becoming CEO of its European division.
He will serve as CEO of Iglo Group, replacing current CEO Elio Leoni Sceti.
"I could not be more excited to join Nomad at the onset of its growth story. The initial investment in Iglo Group creates a solid foundation for us in the consumer foods space,” he said.
Working with co-founders Martin Franklin and Noam Gottesman, Descheemaeker will implement Nomad's growth strategy and oversee day-to-day operations and brand initiatives at Iglo Group.
Prior to Delhaize Group, Descheemaeker was head of strategy and external growth at Belgian-based Interbrew, he was responsible for managing M&A and strategy, which culminated in the merger of Interbrew and AmBev in 2004 to create the world's largest brewer.
At Interbrew (and later InBev), he held operational management roles as zone president in the US, Central and Eastern Europe, and Western Europe. He currently serves as a non-executive director on the Board of Anheuser-Busch InBev, a position he has held since 2008.
