It's not "are you and your product good enough"... It's all about differentiation. Is your offering different enough in the eyes of the customer to gain a foothold in the market? I say "offering" rather than "product" because you need to think broadly about it.

Ask yourself, what is Uber? What is the "product"? Is it getting a ride, or is it the UI on the phone (and the integration of maps and crowd-sourcing) for getting a ride? The answer is ALL OF THE ABOVE.

There were several competitors to Uber but they were the only one to consider their offering/product so broadly.

So, if I were you, I'd be out talking to as many people as I could to find out what you could offer that was truly different that would make people come to you versus the competitors.

Doing things differently is the key to business.
