You could say Facebook co-founder Chris Hughes just wanted to do something good with his billions. But he and partner Sean Eldridge, the political director of Freedom To Marry, also has a great pitch for his new start-up Jumo. The new service, which launches today, “a philanthropic endeavor that works to match people with political movements, nonprofit organizations and other causes,” so it makes sense Hughes (who headed up My.BarackObama.com) and Eldridge are putting their own spin on things: Every dollar you donate to Freedom to Marry, the Empire State Pride Agenda, Gay and Lesbian Advocates & Defenders, and Equality Maryland through the end of the year will be matched by the couple (up to $25k-$100k, depending on the organization). That’s a wonderful philanthropic move. And an excellent bit of free press for Jumo. Win win?
