KYC Automation for High-Volume, Low-Value Transactions

Curious how others are handling KYC/KYB for fintech operations that deal with a large volume of relatively small transactions, especially cross-border. We're finding the overhead of traditional manual review processes, even with some tech augmentation, becomes disproportionate to the transaction value very quickly. It's a fine line between compliance diligence and operational inefficiency. Specifically, what tech stacks or outsourced solutions are you seeing that genuinely reduce friction and maintain regulatory integrity for jurisdictions like certain EMEA countries or parts of APAC, where requirements can vary wildly even within the same region? Are there any emerging standards or best practices for leveraging AI/ML in this space that aren't just buzzwords, but demonstrably improve both speed and accuracy of risk scoring and identity verification for new accounts?
