I've been seeing the very opposite. Fintech companies treating design of financial systems with the casualness of a frontend aesthetic change. And tons of business people integrating their vibecoded POCs with financially sensitive data sources.

Fintech != banking/finance, at least not necessarily.

Would Fintech include orgs like Yotta Bank, Robinhood, Revolut that tried to do finance things with a tech attitude, whereas banking/finance is your more traditional HSBC, Deutsche Bank, etc?
