I can see where the confusion comes from. 2% of YC companies could use SVB and 30% of that 2% can't make payroll. Or 90% of YC companies could use SVB and 30% of those can't make payroll. That's a big difference.
The "No, " at the beginning of my response probably triggered them. I was simply trying to make it clear to others that their information was misleading.
The OP was saying it was at least 30%
