Atlassian gets IPO share price of $27
How much could they grow? It's not clear to me, unless they suddenly have much more ambitious plans and new categories of product, how big the market is that can sustain infinite growth over time for them. The market is very specialized for them, and if they try going after non tech their products directly then go up against many other players already entrenched (and it's not like JIRA is some shiny beacon of ease and apple-like perceived simplicity -- if they rebuilt from scratch maybe they'd have a better chance)
