Many of the nation’s top-tier banks are inching along the adoption curve and redefining themselves as fintechs. With many drawing the spotlight as market darlings, fintechs – led more often by tech whizzes than bankers – are revolutionizing banking through targeted applications of rapidly emerging technologies. In bare bones terms, the fintech mission is to find better ways to do business, whether it’s through a consumer-facing capability or a back-end process. Success lies in carving out a niche by providing sharply focused solutions, usually to a pain point (or two) that regularly frustrates consumers. Fintechs’ size and sophistication range from mom-and-pop virtual startups to subsidiaries of major technology companies, including IBM, which is top ranked for using artificial intelligence in banking. While smaller tech companies with sexy solutions tend to get a lot of the buzz, you can’t have blinders on to the broader fintech ecosystem when your organization is trying to fill in the blanks around what it needs from a capabilities standpoint. Only those banks in, say, the top 10 in assets have the in-house technological horsepower and deep financial pockets to envision and develop these savvy offerings themselves. They might carve out a group of digital talent and establish a think tank, where they leverage design thinking and other smart tools to dream up and build internal apps. On the flip side, some banks are opting to act as venture capital firms, injecting cash into smaller fintechs that, in turn, develop unique capabilities that align with the customer experience banks want to provide. Fintechs embrace agile methodology and the newest technology, often built on more flexible back-end platforms that allow them to execute on new ideas quickly, ship code rapidly and get to market sooner. They cycle through test, learn and adapt in the time it takes a conventional bank to convene a meeting. But all that rapid innovation doesn’t mean they don’t have staying power – this market segment is projected to nearly triple, reaching just under $310 billion by 2022. That means fintechs are doing something right – starting with not trying to be all things to all players. That means banks need to take the right lessons away from the evolution that’s taking place around them.
