No it is not. Regulation in Financial Services exists for a very good reason. To protect you the customer against the various kinds of risks.
When you run a company and borrow a significant amount of money from a lender you do not want that this lender changes terms half-way through because they are in trouble re-financing their portfolio. The same applies to due-diligence in credit underwriting. Social scoring was hailed as the future of credit origination but it does not work at all (yet). No social characteristic is correlating at to defaults.
What if you deposit your life savings or life insurance with a fintech startup and they do not survive (for whatever reason). Then what?
There are a lot of businesses out there relying on a stable financial systems. Fintech companies will work with established players to bring faster technical implementations and MVP's for banks to implement. After they have done their technical due diligence. Beyond that I am more than doubtful.
