BackerClub.co is a club for the best of the best Kickstarter backers out there. The minimum qualification to become a member is 50 backed projects on Kickstarter, but that only gets you in the community as a "Tenderfoot" rank. Projects that list on Backer Club offer discounts or free add-ons to the club members when their project goes live. Club members can give early feedback to creators about things like the rewards structure of the upcoming campaign before it launches.
I'd love to hear your feedback about this community and things you'd like to see in it:
