Tobi has never given me the impression that he's a sociopath. It's part of why I wanted to work for Shopify. I used to joke that "'Shopify is the no assholes company.' 'But what about Kaz?' 'It's the no assholeS company- we're allowed one!'". But honestly, even my view on Kaz softened up over time.
Either the leadership at Shopify are genuinely nice people trying their best, or they are way better than the Amazon leadership at hiding their sociopathy. But either way, it felt nicer working for them.
