"Outsourcing is a strategy that startups cannot live without. When you start as a one-man show and have to do everything by yourself, you find out quickly that some things you cannot do as well as others."

While this is true in some respects, the reason why people do things themselves is to save money - maybe money that they don't actually have.

Of course, a good businessman will raise all the money he wants, outsource everything and just watch the profits role in.

My summary of outsourcing vs. in-house solutions is as follows:

The problem with outsourcing is that it can be incredibly expensive.

The problem with in-house solutions is that they can be very expensive.

(They can both be 'expensive' in different ways.)
