We just use "funded" for that, usually.

Basically, I think the rules I outlined in my first crowdfunding post apply. You would be giving up the wider marketing opportunities afforded by the big crowdfunding sites, but people being able to support via upvotes makes deciding to support easier. As I said, I fully expect to see a Steem based crowdfunding platform to launch in 2018, but you can certainly do it on your own now.
