Ask HN: Where can I find a place to invest small projects and may get returns?

What size of investment are we talking about? If it is significant in size you might want to look at getting in as an angel at angellist.com.

I'm kinda surprised you haven't been inundated with spam, honestly. :-)

This is supposed to become legal in the US pretty soon. waiting on SEC to create guidelines.

I use Prosper.com (if you like it, give me a karma point :)
