Back in 2016 when I first started my first Fintech, we used the concept of virtual bank accounts to innovate in the corporate treasury space by getting rid of reconciliation processes, and fully automating treasury and accounting processes. using APIs and
unlimited IBANs.
We talked to 100s of corporate clients and presented our solution at many Financial conferences. though we got a lot of "wow that is really cool" we never managed to convince any large corporate to use vIBAN technology.
Things have changed a lot since then. large corporates haven't, but covid has replaced huge sections of the industry with digital startups. these digital startups face the same corporate treasury challenges as laws and banking hasn't changed.
But being technology startups they are more than happy to work with banking API or API first card processors like Stripe.
2023 will probably be where Banking as a Service will start being used by startups and corporates.
