Ask HN: What do founders spend their time on, after their product launch?

Seems like all the startup stories you hear, more or less play out like Cinderella, you hear about every minute detail about preparing for launch etc, then you launch, and pretty much end up with "...and they lived happily ever after". Maybe a year down the line you hear about a new version, and a few years later you might hear about the acquisition.

So what do the founders spend their time on after they launch?(3+ months after launch). You know things besides coding new features.
