Onboarding Friction for High-Volume FX/Crypto Desk

We've been running into persistent friction with KYB/onboarding processes across multiple prospective liquidity providers and PSPs for our desk, particularly when dealing with higher-volume FX and crypto flows. The issue isn't just the initial document submission, which is standard, but the subsequent rounds of verification requests that seem to target beneficial owners and operational controls in a way that feels disproportionate to the risk profile, even with solid compliance frameworks in place on our end. This iterative, slow-burn process is delaying market access for new strategies and tying up significant internal resources. Curious if others in the high-volume institutional space are encountering similar headaches, or if there's a specific approach to structuring applications or internal documentation that has proven effective in streamlining these prolonged reviews. We're talking weeks turning into months sometimes just to get a tier-1 connection live. Has anyone found a sweet spot with providers who grasp the operational realities of active desks vs. a more generic 'retail-plus' onboarding?
