>Let's say that a friend of mine has a startup funded account at Chase, and where should they go?

Silicon Valley Bank... oh wait. In all seriousness, the approachability and flexibility of SVB bankers was really unparalleled at the time. Not like Alex in this story, that made really half-baked attempts to engage with a client model he was entirely unfamiliar with (but got all the credit for). This being said, Silicon Valley Bank, a division of First Citizens Bank continues to exist.

I see a lot of Fintech players on the scene now. Brex, Mercury and Rho are common ones, through Brex has taken steps to distance itself from true, seed-stage startups as of late. Given what happened with Synapse's failure [1], I have doubts that they have the same protections and regulations of a brick and mortar FDIC bank.

Diversification is key too - so having multiple accounts. Some non-fintech banks I've seen floating around, ironically, JP Morgan Startup Banking, Wells Fargo Technology Banking Group, Citigroup Commercial Bank, PNC Technology Finance. All big banks, just not their retail banking divisions (as the author was experienced using).
