There are plenty of companies that have been highly successful at growing way beyond their first product or service. If Apple had stopped with PCs, we wouldn't have iPods, iPhones, iPads, etc. The danger is when a startup seeks to grow just for growth sake. Hire way more people than we really need so we attract investors by showing rapid growth is their modus operandi. That approach has actually worked enough that many companies are willing to travel that risky road. But that road is also littered with casualties.
