Interesting article here…Simon West ('Expendables 2" director) is going to start crowdfunding his next project(s) using the site SyndicateRoom (which I've never heard of, of course). SyndicateRoom seems to be trying to distinguish itself by going after slightly more premium projects and those projects will have been vetted by, and invested in by, 'professional investors' (a term I also have never heard before!).
Both the article and the SyndicateRoom website might be of interest.
