On the topic of FDIC insurance and startups... I'll put in a shameless plug for a startup I helped launch 20yrs ago: *Promontory Interfinancial Network" https://www.intrafi.com/solutions/depositors/
It was a startup them (now acquired), and created a bank deposit product "CDARS" which took customer deposits and distributed it across (k = N/<FDIC Limit) banks and kept the relationship as a single bank with a single account.
Even cooler, as k other people did it at k other banks, the service would just swap deposits across all the banks. It was a super-cool and valuable product, and i'm proud to say I helped write the matching engine for it back in 2002.
I realize this doesnt help startups with locked funds at SVB, but I'm pointing out -- there are options out there to have 100% FDIC insured safety for both individuals and startups.
This is a rather specialized and technical area of finance, and like most technical areas, I imagine it's hard to search for unless you know the magic terms and jargon to search for.
Lloyds and AIG will insure just about anything, they'll happily protect $x million or billion for a nominal fee.
It hasn’t to be this situation, but if your accounts are flagged for fraud or someone hacks an account, aren’t you safer by distributing cash in multiple banks?
