The transition from fintech startup to scaleup represents a fundamental shift in both scale and ambition. Initially focused on solving specific financial pain points with innovative technology, these companies have evolved into comprehensive financial ecosystems serving millions of users worldwide. 

This transformation typically involves securing multiple funding rounds that drive valuations into the billions, while expanding from single-product offerings to multi-service platforms. 

Successful scaleups establish themselves as essential infrastructure, processing hundreds of billions in transactions annually and powering thousands of other applications.

Below, we bring you our Top 10 fintech scaleups.
