You are right about it not being a fintech startup, and 40 years is a lot for those (as well as tech companies). But even then Apple, Intel, Oracle are all older than SVB. And in the banking industry, 40 years is nothing really. The "oldschool" banks have usually gone through a history of mergers and acquisitions for hundreds of years. Usually this means founding dates somewhere in the 19th century, say Deutsche Bank which was founded in 1869.
