Thanks for your email and interest in Collabhouse.
When you create a release you will be given the option to 'Create a new artist' when adding the artist(s) to a release and track. At this time you can indicate that this is a brand new artist and request a new Spotify & Apple Music profile.
It then takes approx. 5-7 days for the new artist profiles to be created on the platforms after the release has been submitted for delivery. You will then be able to claim these profiles using Spotify's 'Spotify for Artists' and Apple's 'Apple Music for Artists'.
