losing 20% of your cash-on-hand, where that's above $250k. For most startups, that's going to be a haircut their investors take, where the founders can say "yeah, literally none of this was our fault".
For mature, profitable businesses with recurring income, this is going to bite, but they haven't lost 20% of their customers or 20% of the amount of money they expect to get paid next month.
For startups, where the money was investment, unlikely their investors are going to blame them for this loss. It might shorten runway by up to 20% for some pre-revenue startups, by less for startups with actual revenue.
