The 100 Men Who Care concept of crowd-sourced philanthropy traces its roots to the first 100 Women Who Care chapter started in November 2006 by Karen Dunigan of Jackson, Michigan. She conceived of this simple idea as way to raise money efficiently and quickly for local charities. Her group of 100 women, at their first one-hour meeting, each wrote a check for $100 directly to the charity, raising $10,000 to buy 300 new baby cribs for an organization in their city. Since then, 100 Women Who Care and 100 Men Who Care chapters have sprung up all over North America and beyond–including the very successful 100+ Women Who Care Central Oregon chapter. These groups collectively have donated more than a million dollars to locally based organizations.
