YC isn’t the only set of companies that used Svb, they’re probably representative of the distribution of startups that need banking
I think a lot of startups are in this situation. They have SVB accounts, but likely don’t have all of their money in there.
One thing to remember, SVB is very founder friendly. Often giving companies favorable lines of credit, giving founders favorable mortgages, etc. They helped us tremendously with our PPP loan, and are also deeply integrated with products like Stripe Atlas.
