When someone brags about how little sleep they get, I've found it difficult to convince them that extreme sleep deprivation impacts performance. It's not too dissimilar to a drunk friend trying to negotiate back their car keys -- introducing ludicrous levels of denial seem to be part of the mentally-impaired package. Perhaps a bigger warning sign is when / if a founder like that ends up using and abusing amphetamines. I used to work at a startup where the VCs did a clawback due to the founders erratic, amphetamine-induced behavior. Either way, a simple observation: you will be most effective when you trust the judgment of the person you work for. I highly recommend optimizing for how effective you are when considering where you work.
