Two Groups That Help Nonprofits in a Merger

GOOD, a fast-growing publishing and marketing business that promotes social causes, is acquiring Jumo, a social networking site that raises money and support for nonprofit groups.

The deal may signal the beginning of a consolidation in the world of online intermediaries set up to help nonprofits, which have proliferated in the last few years.

Jumo will drop its name and become tied to a growing audience that includes GOOD’s online magazine with an estimated three million unique visitors a month and Good’s nascent advertising and marketing business, GOOD/Corps.
