Hi Mike,
Interesting read. Let me tell you my thoughts about the team sourcing platform idea in general.
Technology is rapidly growing, conventional jobs are dying out, and more and more people are teaming up to work on specific projects. The whole startup movement is a clear sign of this. For that reason, I believe a crowdsourcing platform is a brilliant idea with huge future potential.
Now to the execution! I visited your website and the first impression was good, but as xaviersythe already mentioned sketchy.
After reading all the information available I didn't really know how the platform works and what it will cost me. Information missing, not many photos of the actual work environment, etc. I am eager to find out how the control center actually looks like, but again, not much information besides the Nucleus page.
I assume the platform works with a task management system similar to scrum where every task has a set amount of points. By completing the task team members collect points which will later determine how much payment each team member is going to earn at the end.
Regarding the 5% revenue share, I don't think revenue share as your income source is a good idea, especially if you want to attract promising projects. There is a reason why major parties like unity don't work with models like this.
Also, I don't think a marketplace would be the right focus for your platform. I don't see it as essential for the whole project, more of a distraction for you and your users.
I hope my message is not misleading, I do think you are doing a pretty good work, there are issues, but what project doesn't have issues? Especially in the beginning. What I see as the most important issue is the focus part, it is what helped me the most to grow and advance with my own projects.
By the way, I submitted my actual project to the platform. I am really curious to test it out now that we are looking for new team members.
P.S. Sorry for the bad grammar, English is not my native language but I try my best^^
Good Luck,
André
