Pros
1. mature people: i have yet to feel like i need to play office politics or do any song and dance routines for anyone, ever. People are laid back, take their job seriously (without being weirdly obsessed with it) and respond like adults to criticism 2. functional processes: unlike most startups i've worked at, it doesn't feel like the processes here are taken directly from the latest volume of "startups for dummies" - instead, they seem to be anchored in experience and practices which work for the teams using them. 3. reasonable policies: i can take holiday or work from home without feeling guilt-tripped (explicitly or subtly) about it. 4. actual culture: this is a mix of #1 and #2 in my opinion...in my experience it has been a drama-free work environment and i don't feel like i'm being asked to participate in some kind of social experiment / reality tv show in exchange for a wage. It's entirely unforced. None of the points i mentioned should be shocking but alas... On top of that, the product is sound and everyone from customers to investors seem satisfied.
Cons
Maybe this is an elaborate hoax and at some point the curtains will be swept back to reveal the normal startup hellscape...but i don't see it. One time there was no toilet paper in the bathroom...does that count?
