This sounds like a great new platform! I always like the idea of something made ‘by artists- for artists!’
To answer your question, over the years we have enjoyed working with various agents. Some have taken far too steep cuts for their services, and others have been more fair in their booking fee/ commission (10-15%) so they are the ones we continue to work with. I think it’s important for any platform to be very transparent and user friendly from the act and also the clients point of view.
Booking terms should be clear cut- so everyone knows where they stand on T&C’s (including the agent). They are some of the things we have liked about our agents. Hope that helps and I look forward to seeing how Gigstarter progresses!
