CIG raised about $6,000,000 on KickStarter if I recall correctly. Almost all of the crowdfunds came after they moved off KickStarter to their website: robertsspaceindustries.com
No need to rely on memory. From the KickStarter page [0]: "$2,134,374
pledged of $500,000 goal". However, it looks like the graphic showing $6M achieved combines the $2M from KickStarter plus additional funds they raised directly on their site.
Really good ROI for a low-to-medium complexity website, and a company of 129 employees.
