Not just that, there are numerous other variables. e.g. The environment,I started my company in India when there was no definition for a startup, so my startup was no different than a Billion dollar corporation from the eyes of the government.

So, as a single founder I spent much of my initial years trying to learn all compliances & adhering to them(there are dozen new ones every month); while the product development went un-interrupted through the developers (whom I personally trained) & via automated systems.

Startups in a better environment had a competitive advantage of having to focus only on their company's growth even when being a single founder.
