Getting the first 10-15 paid users?

I am curious with a few perpetual questions popping in my mind.
How important is it to satisfy the quench of a SaaS founder to gain the first 10-15 paid subscribers when you launch a product?

Also, suggest a few effective methods to gain those first paid subscribers.
