Maybe we need something like a crowdfunding platform, but instead of the campaigns being organized by producers of products looking for customers, the campaigns could be organized by users who are looking for someone to solve a problem they have? The customers could give grants to developers/entrepreneurs to work on a solution to the problem, sort of like the SBIR process. You'd need some sort of grant proposal vetting system -- perhaps the donors could individually approve whichever grants they want their money going towards, and if multiple grants are approved by a sufficient quorum of donors to meet their minimum funding threshold, then you could have multiple teams working on the same problem. There would be a lot of details to work out, but this is starting to sound like yet another startup idea.
