Most every entrepreneur I meet struggles to crisply articulate their value proposition. I solve that problem.
However, clarity of a value proposition can be a double edged sword. I was working with an entrepreneur last week, helping him get to the essence of his company. When we did I realized that it would not get funding.
I told him candidly that it would be very difficult to get this funded, even in the best of economic environments (not an easy convo to have). I know the whole Google argument about how people would have turned that down.
But for every esoteric (at that time) idea of differentiation like Google, there are 100's maybe even 1000's of companies that have a business model that won't and shouldn't get funded (like the one I'm referring to). My best advice to the entrepreneurs in that situation is to keep the idea going perhaps as a side business (or shut it down) and move on to their next big idea.
