Isn't it crazy to hold $300M just sitting in the bank? I have pennies for a net worth comparatively and I was taught to keep my money spread around, and not all of it just in cash in the bank. But also, I am ignorant to how a start up operates.
Should Rippling have spread those funds out over multiple banks? Maybe. But more moving parts means more room for error, more complicated accounting, and more operational overhead. There is (was?) a compelling argument that you're more likely to goof up juggling $300M than a bank like SVB is.
It's a bank then!
