Why wait till regulators come knocking on the door? As startups begin lean and adaptive, they are capable of building systems that fit the constant shifting regulations. Fintech startups especially need to keep track of these regulations, and can mitigate future risks by implementing compliance measures early in product life.
A startup, on the other hand, can build a product with the needed capabilities in mind at the outset. Factoring nimble compliance into product design will attract savvy investors and, perhaps more importantly, smooth entry into established markets.
