Cross-border KYC harmonization for smaller fintechs

Been pondering the challenges smaller fintechs face in scaling KYC/KYB across multiple jurisdictions. The larger players can throw significant resources at compliance teams and tech stacks to manage diverse regulatory landscapes, but for a startup operating in, say, 3-5 EU countries, the cost and complexity can be crippling.

Are there any emerging platforms or best practices for achieving a degree of KYC harmonization that doesn't involve building out entirely separate compliance frameworks for each new market? Specifically, looking at solutions that cater to mid-market transaction volumes, not necessarily institutional. Or is it simply a cost of doing business that smaller players just have to absorb, limiting their expansion speed?
