Thanks for the response. I know it's a good idea because it's already something that's being done in the real world, but no one so far has made it easy to do for people online.
Think for instance about how Amazon. People were buying books before Amazon existed, but Amazon made it possible for them to order books from the comfort of their own home; so the founder/CEO of Amazon Jeff Bezos did not need to re-invent the wheel; all he had to do is target an existing need for people but make it easier for them.
My business does the same thing; makes it easier for people to do something that they're already doing. I've gotten positive responses from the people I trust enough to share the idea with in real life; mainly family members, since I know that they won't launch a competing product.
I know that appearing on TechCrunch doesn't guarantee that a company will succeed. However, often times a TechCrunch article has to do with a company raising a round of funding, which is what I'm really scared of; that I would start a new business and 6 months down the road I see that another company has launched with funding, targeting the same area. I'm removed from Silicon Valley, as I live in Southern California, so it's not easy for me to raise money the way it is for people in the valley who have connections.
Ultimately I think I just have to work harder than any potential competitor and hopefully that will mean I succeed in the end. I'd rather do that than to sit on my idea and watch someone else create the company that I should have created. Once again thanks for your response!
