Onboarding Friction for Mid-Cap HFT Desks - KYC/AML Realities

Anyone else finding the KYC/AML process for new broker/venue onboarding to be increasingly convoluted for mid-cap prop desks? We're not talking about retail accounts here, but legitimate entities with established track records. The due diligence requests from various tier-1 and tier-2 providers seem to be diverging significantly, and the timelines are extending. It's creating unnecessary friction and delaying liquidity access, which directly impacts our ability to capitalize on transient pricing inefficiencies. Curious if others are experiencing similar bottlenecks and how they're managing.
