thinking maybe there should be Startup Construction Kit and How to Get Funding materials for the case of "your whole team thinks it's going to be laid off, or it's morale has been decimated and everyone's thinking of leaving"

because it seems to me that one of the best ways to punish layoffs in the short term is turning layoffs into something that generates competitors.  It's an industry where that's actually possible still. And there's a long history of it.

Laying off entire small companies worth of institutional knowledge?

Wild. Good luck with that, mate.
