Marco Geeratz - CEO/ Managing Partner
Connecting people & companies

About Marco Geeratz

After my studies I have held various marketing positions at both agencies and advertisers in the Netherlands and the United States. Based on the discontent concerning the marketing executions within those companies I decided to start an agency specializing in this matter in 2003. This agency became the foundation of Sumis, which, after the take-over by Kobalt, has developed into market leader in the Benelux. My strength is connecting both people and companies.
