Talk to anyone in the treasury function at any company of any reasonable size, most of them will be doing it.
You’re getting lost in the current context of what you assume to be SVB’s majority customer; the banger ‘unicorns’ we’ve all read about over the last decade, who would/should have this ‘treasury department’ you’re referencing.
Zoom tf out, remove SVB, and tell the guy who fixed your fucked plumbing last go around that his lack of a treasury department and/or insight into what his primary bank is doing with their deposits is a major problem and they deserve to eventually get fucked because of it. I’ll wait…
The comments above are about companies with millions of dollars. It starts with someone talking about $5 million.
