You're right that traditionally credit unions and community banks have used antiquated consumer facing tech (online banking, mobile banking, loan applications, online account opening, etc) owned by 1 of 3 OG financial technology companies in the U.S.: Fiserv, FIS, and Jack Henry. They are all multi-billion dollar public companies that have formed primarily via acquisitions.

I started a company to challenge the incumbents after running a credit union as CTO.
