Cryptocurrency is soaking up attention, but financial services technologies involving fiat currency have also never been hotter. This week we continue our special five-episode series on The Information 50, our annual list of the most promising startups valued at less than $1 billion, by taking a look at five fintech startups that made the cut. In this episode, The Information’s Amir Efrati speaks with reporter Kate Clark about the startups that made our list, why “banking as a service” is on the rise, and why this year’s record $87 billion in fintech startup funding doesn’t represent the peak. Then Kate interviews Itai Damti, co-founder of Unit, the top startup on our list, and Henrique Dubugras, co-founder and co-CEO of corporate card startup Brex, about the fintech frenzy and what’s coming next.
