In the past few years we have seen the rapid evolution of FinTech from generating novel ideas which solve customer problems, to offering core financial services. We have seen the shift from digital startups, characterized by a lack of financial wherewithal and which operated on the edge of tightly regulated markets, to the emergence of mature financial digital organizations at the heart of the traditional financial world.We can describe the development and maturing of FinTech in 3 main waves:The early emergence of digital startups helping consumers. Originally FinTech solutions were the preserve of B2C markets which solved specific customer problems such as offering home loans faster and easier. They used new technologies such as mobile and cloud computing, and were characterized by a laser focus on the customer with all the hall-marks of a digital Silicon-Valley style start-up.Transition to B2B markets. Today FinTech plays a role at the core of B2B innovation in financial markets, and industry observers widely expect B2B FinTech revenues to dwarf those in consumer markets within the next couple of years. Organizations such as Currency Cloud (cross border B2B payments), Payoneer Escrow (escrow services), and Hummingbill (B2B invoice platform) all reflect a maturing industry.The creation of an ecosystem between FinTech and traditional players. FinTech organizations are realizing that the required go-to-market investment, economies of scale, and regulatory needs, means it makes sense to partner with traditional financial institutions. On the other side, established players recognize the value, innovation and potential of FinTech in a world which is increasingly mobile-first. These financial institutions are also adopting many of the methods that FinTechs use so successfully, from a focus on the customer, to using Agile software development, to holding hackathons, and forming accelerators and innovation programs.
