I've seen a couple startups with ~10 people and no market fit paying $500k/y to hire a FAANG VP. That's even more damaging than a fresh grad kid managing 50 people!
Getting the FAANG VP is usually critical to landing the next round of funding. If sending $500K/year [1] out the door brings in $50M for your next round of funding, it's well worth it. Particularly if you recognize that your enterprise is a Ponzi scheme [2] and that getting that next round of investors is how everyone gets paid.
[1] seems ridiculously low BTW, that's a line manager or extremely skilled software engineer at a FAANG, VPs make multiple millions per year.
Thinking about it, market fit would be the latest point to hire an experienced adult. Preferably from one to two levels below the role a start-up is hiring for, e.g. director level for a VP position.
Maybe hire earlier, as soon as an adult is needed to set up proper structure, processes and operations. If a company screws this up, e.g. when inexperienced founders hire former COOs and senior VPs from big names for those big names only, things can turn south pretty well.
