I disagree, most companies don't really 'grow' like you're suggesting. The odds of joining a company like AirBnB, DropBox, Facebook, etc... While in its early stages approaches 0% - There is a massive amount of luck involved. These kinds of learning opportunities are essentially impossible to come by. However, if you switch companies often and work for a range of companies at different stages of development, then there is a very good chance that you will have the opportunity to learn about all the different stages of development without putting all your bets on one horse. 99.9% of the time, the single-company mindset that you're suggesting just gets people stuck in a rut (I've seen it). If you've had a different experience then you're one of the lucky ones.
