The company Downtown Event does not only organize but also sponsors the Balloon Jam Hamburg. The company’s manager as well as the Jam’s host is Andreas Zier.


Our main sponsor is Pioneer Europe Ltd. We get most of the ballons from them. A big thank you for that support.


A part of the balloons also comes from DM Balloon Company. They don't only  sponsor us, but also have a shop at the jam where you can buy balloons and  equipment for discounted rates. Your support is greatly appreciated. 


The location “Der Sunderhof“  is a fabulous facility in the middle of a forest. We can satisfy our passion ‘balloons’  by twisting and popping balloons as much and as loud as we want to because nobody disturbs us. The whole site is exclusively booked by us. 


"Air Products is the world's leading supplier of helium, bringing extensive experience to the balloon gas industry. The 300 bar Balloonium® cylinders are not only lighter than standard cylinders, but also contain up to 50% more gas than conventional gas cylinders. The lower operating pressure ensures greater safety. The simple quick connection, the integrated pressure regulator and the level indicator ensure high user-friendliness. Contact Air Products".

Thank you for sponsoring the Heliums.
