Atlassian make a big point of saying they don't have a sales team[1] so I am not sure where this is coming from?
They pay people to convince other companies to buy their product. The claim of "no sales people" stems from the fact that they only talk to people who contact them, rather than cold-calling.
This is, interestingly, also what the sales team at my company does. They are pretty sure they're doing sales, though, so we call them that.
