Most of the interesting stuff about how companies grow come down to a relative small period where some key decisions get made (in the tech world at least). Anyhow, this is normal and people love to try and parse the lives of the wealthy to see if any of it can be applied to their life to capture some of that success. There are a lot of things to increase your luck potential, but it still takes grit+luck.
I really don't think so. Case in point - The article describes a 17-year growth path for Atlassian, including many reversals along the way.
What you're describing is the exception. E.g. Minecraft. Most successful tech businesses (like all businesses) are built on a combination of luck and sustained good decision-making and hard work.
