I began a project with this after the pitch/initial selection phase - but due to personal circumstances had to withdraw about 40% of the way in and concentrate on other things.

Due to the specific arrangement we had, I (understandably) didn't get paid anything, although the idea is still on hold to be resurrected when I'm more able - although this may be as a solo project then.

The concept and semi-anonymous funder are certainly legit and I'm interested to see how the other projects from this develop.
