A couple anecdotes about timing: I remember one of the Unity founders talking about how they essentially built a ship in the desert (a user-friendly game engine for Mac) and then a flood came for them to ride (the iPhone app store and all its games). And in a similar vein, one of the founders of a European ride-sharing service, GoMore (in case you don't know them, it's an actual ride-sharing service, not a taxi-service-disguised-as-a-marketplace like Uber) said that he'd essentially had his company in hibernation for several years when the smartphone revolution happened and suddenly they time was right for them to grow.
