Before I ever got another pair of eyes on the product, I had built every single feature. It took nearly a month to get it all together and ready for users. So the product has only been around for 4 months, it only took a month to piece it together and get it ready for the public? Doesn't sound like you've failed to me, you've only just started. Starting a new company with no rapport with anyone isn't just going to burst onto the scene and people throw large amounts of cash, trust and praise at it. Marketing to small businesses isn't easy, you've got to build trust first. And by the way just by launching the product instead of burning through savings and investment capital for a couple of years you've succeeded in that I've seen tonnes of ideas and startups fail because they couldn't get a product finalised and out the door for people to use. You've launched something, be proud and keep working at it.
