Hi Korbinian,
If you want to run mutually exclusive experiments and feature flags, we will recommend to keep one org but leverage our namespaces feature.
For context, Namespaces in GrowthBook are used to make multiple experiments/feature flags mutually exclusive. This is particularly useful when you have multiple experiments that may conflict with each other.
Users are randomly assigned a value from 0 to 1 for each namespace. Each experiment in a namespace has a range of values that it includes. Users are only part of an experiment if their value falls within the experiment's range. So as long as two experiment ranges do not overlap, users will only ever be in at most one of them.
To use namespaces, you need to create a new namespace or modify an existing one in the GrowthBook UI's left navigation bar under _SDK Configuration → Namespaces_.
Here's an example of a namespace tuple that specifies what part of a namespace an experiment includes:
["namespace1", 0, 0.5];
In this example, the namespace id is "namespace1", and the experiment includes the range from 0 to 0.5.
Further info on this can be found here-

Hope this helps :)
