Meetup.com is a website that allows people to organize local groups and activities face-to-face in their communities. It was founded in 2002 and now has over 13 million members in 45,000 cities. The New York Gaming Meetup case study shows how one founder used Meetup.com to build a gaming fan community in New York City, growing to 3,000 members within a year through consistent monthly meetups. While non-profits like Bread for the World could benefit from Meetup.com to engage supporters, they may face threats like lack of interest or pressure to donate.
