Culture - I find the engineering culture great, lots and lots of trust, everyone deploys at all times throughout the day, freedom to experiment with new technologies. No one points fingers and the team is all in it together. Non-engineering wise, there is a ton of respect for each other on the team, it's a super positive place to work.

The people - you'd have to get to know them, they're awesome bunch :)

Our values - here's the easiest way to show them: http://www.slideshare.net/Bufferapp/buffer-culture-05

I hope that helps a bit!
