Not parent - but I've noticed those same 'start ups' and they just seem to be today's hustle-bro crypto/drop-ship/mobile-app/ceo-with-no-employees/self-help-book/low-effort grift (bullshit).

I'm sure some of them have managed to shake some change out of the VCs but these wanna-be shovel sellers are just gonna let their domains expire and move on to the next scheme with little overall damage to the economy.
