The problem was that programming comes before marketing & business. I mean there is an idea and a plan ofcourse and you try to validate that as much as you can, but basically, after that, the programming/development phase kicks in, which was what we did for our %. When the business person/inventor/cofounder(s) after that said; 'oh we tried to market but failed, ah well, shame' then you are stuck with 20% of nothing while you did the work already. Now that I have far more business and legal sense, I don't think there is much of an issue doing it again.
