Earlier quoted context omitted.
$1200/year, not per month, and according to this tweek the business had "tanked" in recent years: https://twitter.com/monstro/status/585797874300035072 . Edit: Actually $1200/month according to the pricing page, nevermind. That's insane, and way above competitors like ZenDesk.
Are we thinking of the same Zendesk? The Zendesk I know is a public company with 9-figure topline revenue.
Granted, they are slightly different products; I was just grabbing the nearest competitor I could think of. (They're in the same space, though, and competing directly for the community/knowledge base part of their products.)
