Onboarding Friction for High-Volume FX/Crypto Firms

Anyone else hitting a wall with KYC/KYB for new broker or PSP relationships when your projected volume is significant from the get-go, especially in the crypto-FX cross-over space? It feels like we're constantly justifying our operational model, even with solid regulatory standing in our jurisdiction. The due diligence process is becoming a multi-month bottleneck, sometimes causing us to miss market windows or delay product launches. Are there any specific red flags you've found trigger the most scrutiny, or have any of you found a way to significantly streamline this without just throwing more bodies at compliance questionnaires?
