Agentura rotunda s.r.o. is a Znojmo-based organizer that stands behind the modern Znojemská Rotunda Open festival. The company is based in Znojmo and appears in the official festival footer as the organizer of the event. Its corporate registration dates back to 1996, which gives it a long legal history even though its public chess identity is tied mainly to the Rotunda festival project.

The organizer has built a clear chess profile through the renewed Znojemská Rotunda Open in cooperation with SK GPOA Znojmo. Public festival materials show a multi-event structure with classical, youth, blitz, and rapid tournaments in Znojmo. The official site also presents a small but structured organizing team behind the festival, which gives the company a visible role in tournament delivery rather than only background administration.

For organizer-profile purposes, Jakub Marek is the strongest main contact person. The official contact page lists him as Organizační ředitel festivalu, while FIDE tournament information names him as Chief Organizer. Zdeněk Molík also appears in an important leadership role as festival director. However, Jakub Marek is the clearest organizer-facing contact for communication and event operations.
