Need advice on online betting game provider

Does anyone have insights on iGaming providers? I'm working on a platform and considering collaboration with an iGaming provider. I've consulted with a United Game provider, and they offer game products and a management backend. However, they don't interfere customer data or platform transactions. Their settlement model involves monthly commissions based on the actual platform profits, ranging from 3% to 6%. Does anyone have experience with direct collaboration with a provider in this field?
