Onboarding Friction for Neo-Brokers - KYB/AML Costs vs. Customer Experience

We're currently scaling our crypto neo-brokerage, and the friction in our B2B onboarding process for new clients is becoming a real choke point. Specifically, balancing robust KYB/AML procedures with a smooth, rapid client experience. Every additional step, every document request, adds to drop-off rates and internal processing costs. For those running similar platforms, what's your approach to streamlining these essential compliance hurdles without compromising security, and what tech solutions have you found effective in automating parts of this for a better CX? We're looking at various AI-driven identity verification tools, but the integration overhead and data security concerns are significant. Are you finding third-party providers worth the cost, or are most still building these solutions in-house?
