Ben Goldhirsh started it in 2006. It seems like it's been around much longer.
"GOOD was born out of a frustration that there was no media platform celebrating, covering, and elevating the emerging movement of individuals, businesses, and organizations pushing the world forward. The mission has evolved over time. We now see ourselves as an editorial led, member driven community, with a mission to provide content that coalesces this community, experiences that deepen the relationships within the community, and utilities that empower the community."
