How Can You Create Credibility for Your Customers?

If you don't have a big, flashy corporate name to kind of throw around, how can you establish that credibility? What i did is i started on a very local level, giving free talks at co working spaces, at the brookyn chamber of commerce. And that's how i made myselfe even more attractive to brands like nbc, or brooklyn brewery or a standard hotels. But it started like real grass roots. So what i would say is, you get credibility based on the result you're delivery, and you have to find a way to do so.
