Mike, so who, exactly, is your ideal prospect? Are you targeting individual developers or enterprise dev orgs? Its clear from this thread that you have an education challenge.
In 1991 i had this idea about how to solve a business problem with a large addressable market - how to make it easy for business people to manage their business relationships and related data. The problem was the communication mechanism. then the internet came along. In 1998 i filed some patents. In 1999 we pitched investors. Users (business people) clearly understood the pain. VC clearly understood the pain. At that time, however, almost every investor's understanding of the internet was in the form (use case) of a website. We were not building a website. We were building this "service" that used the internet (http) to communicate. Then we would get lost in the weeds about "so, you are a service company". Frustrating. A couple years later someone coined the term "web service". that cut our education time in half. A couple years after that someone coined the term "social networking". voila, magically we could communicate in 4 words what used to take 20-30 minutes - 2 to 3 X the attention span of a typical venture capitalist. Today you could convey the concept in just one word: "LinkedIn". It's possible that you are in a similar position - you could be ahead of the market, which is great, but an educational challenge. You likely need to target your prospects with a rifle not a shotgun. Also, tactically you might consider video to help reduce education time.
