Perhaps they meant the stock market? I also thought "man, I guess I missed where Atlassian went into the cloud storage market" when I read the first paragraph.

I would assume that the write assumed that "online collaboration tools for businesses" is a single market, and ostensibly both companies can be said to sell products in that space, but yes, I agree that it's less than apt.

That might have been a slight misunderstanding on the writer's part, but I'm sure the atlassian guys are considering box's market as well. If a company is already spending money on Jira and stash for developer collaboration, wouldn't offering content management as a product be compelling? If the engineering department at a company is heavily invested in atlassian products, maybe marketing or sales would give their cloud content sharing product a shot too.

Well, content management is handled by Confluence.

I saw that as perhaps a way to compare Atlassian (mainly BitBucket) to Github

Atlassian is to Github as Box is to Dropbox ?

I think you're giving the reporter too much credit :)

Also, Atlassian is a good deal bigger than GitHub (if measured by revenue, profit, people or valuation), which would seem to put them on the Dropbox side of the analogy

Which is an interesting thought because the common perception (from my chair) is exactly the opposite. A matter of skewed perception, etc, etc.

I think the Bitbucket piece is smaller than Github. But Atlassian also have a whole bunch of enterprise-oriented products, more in the same kind of market as Thoughtworks or one of the big enterprisey lots.
