Why a company should buy from a Startup?

As per my experience, there could be potentiall two simple reasons why a company should buy a product/service from a startup:

1. The person buying has a very good relationship with the entrepreneur, or
2. The person buying has a dying pain that they (i.e customer/company) feels can be solved by the startup’s solution.

If you are running a startup, just try focusing on the above two it should really help boost your sales.
