2019 might prove to be a turning point for challenger banks as they turn towards the next decade with the vast sums of money they have raised; investors have poured in hundreds of millions into startups that have yet to prove they can turn a profit but have acquired customers at an impressive clip; the long term question is can these banks eventually figure out how to reach profitability and what will they look like when they get there; financial services has gone through a period of unbundling and now it seems as if we have started the phase of re-bundling; slick apps have started to turn their attention to diversified revenue streams to try and keep up with lofty valuations as banks put pressure on their businesses by creating similar products; we are a long ways from figuring out winners and loser but the money train keeps going as investors continue to feel confident in challengers.
