Onboarding for new fund – KYB headaches still a thing?

Setting up a new systematic global macro fund and the KYB process for various prime brokers and counterparties is proving to be… a journey. Even with all the supposed advancements in digital onboarding, it feels like we're still supplying the same paper documents we did ten years ago, just now in PDF form. Anyone else finding this surprisingly clunky for new entity setups? It's like they want your AUM, but also want to make you jump through every hoops imaginable to actually give it to them.

Specifically, the varying requirements between top-tier PBs and smaller, more agile liquidity providers is a constant source of amusement (and frustration). One wants three years of audited financials from every single linked entity, another just needs a utility bill from the founder's nan. Seriously, is there a dark art to streamlining this, or is it just the cost of doing business in a regulated space? Feeling like I'm compiling an archaeological dig's worth of documents.
