What does "Hybrid Event" mean?

In wake of the recent global developments, it has become more and more challenging to travel for many people from all over the world.

We will still host the company exhibition as well as the networking evening with dinner for all presence participants… but you will have the option to either attend in-person in Stuttgart… or via livestream on the internet.

This way, you get to attend the event – without having to travel or leave your house.

You will be able to choose your registration once registration is possible.
