I'm working on a tool web developers and project managers can use. It's a very useful tool that i know will solve real problems and make life very easy, while also saving time. I've spoken to a project manager (my work colleague) about this, and she was very excited and eager to start using it.
The issue i'm having is finding my very first set of customers for this tool. I'm in the process of building and will finish it soon. How can i find people willing to pay for this, even though i'm new and they've not heard of me before.
