Onboarding for corporate accounts, KYC/KYB headaches

Anyone else finding the onboarding process for corporate accounts, especially for prop firms or those with complex entity structures, becoming increasingly glacial? The KYC/KYB demands seem to be escalating, and it often feels like a black box for required documentation. Specifically, challenges with proving beneficial ownership across multiple jurisdictions, or getting clear guidance on acceptable UBO documentation. This isn't just about one broker, but a general trend across various PSBs and even some regulated venues. It's tying up significant operational time, and frankly, impacting time to market for new trading strategies. Is there any workaround for this friction without compromising compliance?
