Atlassian

There's no shortage of interesting challenges and projects, and you are afforded a large amount of autonomy. The social aspect of the company is phenomenal and quite unlike any other I've worked for.

Lack of guidance and mentoring sometimes masquerades as "autonomy".

Sunken cost fallacy can take hold, and projects either reach a local maxima or can drag out far longer than they need to as a result.

Check outside the company to contrast the industry's pace of progress with Atlassian's.

Be less afraid of making the decisions to kill off poorly-performing or old features; it is okay to start again if it means building something customers will love and find more useful.

Assign owners to features and services so the buck stops with somebody, as opposed to being left to the aether or someone's spare time.
