KYC automation challenges for non-standard entities

Curious how firms are handling KYC for complex or non-standard entity types, particularly those operating across multiple jurisdictions. We're seeing an uptick in structures that are harder to verify purely through automated database checks, often requiring manual deep dives into beneficial ownership layers or bespoke documentation requests. This significantly impacts onboarding times and resource allocation. What are the current best practices or tech solutions you've found effective for streamlining these trickier cases without compromising compliance standards? Specifically, how do you balance automation goals with the need for thorough due diligence on entities like DAOs or trusts with layered structures?
