KYC Automation for High-Volume, Low-Value Transactions

Curious how others are handling KYC for new accounts that start with very small initial transaction volumes, say under $100 equivalent, but where the potential for a user to scale up quickly exists. We're finding the full onboarding process, while necessary for compliance, can create a bit of friction for these 'tester' users. Has anyone implemented a tiered KYC approach that allows for a smoother entry point for low-value transactions, perhaps with enhanced monitoring and automated triggers for further verification once certain thresholds are met, without compromising AML requirements?
