I doubt this person would feel the same if Stripe had been a failure. Articles like this encourage companies that don't have product-market fit (no amount of 15 hour days will fix product market fit, sorry), adequate talent, nor adequate resources to imitate this kind of culture. The end result isn't pretty.
I might be biased because I could never imagine myself working this hard for an Internet payments platform (noting that in 2015, Stripe was already worth $5B. This is not a seed or Series A/B scenario). Maybe it's because I came from bio- and medical engineering where the people who work this hard save lives and cure diseases.
