13 yr business growth specialist here and mentor at ATL Tech Village. I think I need a bit more information before rendering any advice. This is what I understand so far - you have an idea, a website and some cold-call originated sales. Were any of these sales significant? Did they renew? When you said, "we have channels" did that mean, "we have exclusive agreements with these companies" or that you know who they are? When you originated the idea and began talking about it, who in the market space (other than yourselves) got genuinely excited about it? For anyone to suggest an answer to your question (cold calling or otherwise) would be a guess at best or irresponsible at worse (cash burning) until we know exactly who would "care" about your offering - your solution. Once we know this we can then decide how best to approach a marketing and selling strategy.
