100MARIN is Marin County’s premier members-only giving circle.  Founded in January 2015, the group now has over 300 members.

The giving circle concept is not new.  Started in 2006 by a group of cause-minded women in the Midwest, there are now hundreds of giving circles nationwide and abroad. 

Here’s how it works:

  • A group of individuals commits to an annual donation schedule, e.g. giving $100, 1-4 times/yr
  • They then convene on that same schedule to hear presentations from 3-5 local nonprofits
  • At the end, a vote is conducted to determine which organization will receive the group’s pooled donations
  • The awareness and engagement opportunities for both the nominated charities as well as the non-profit community at large are increased
