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

We are a group of individuals who come together to make a difference in our community through collective giving. By pooling our resources, we are able to make a greater impact than we could on our own.

The giving circle concept is not new. Started in 2006 by a group of cause-minded women in the Midwest, giving circles have grown in popularity in recent years and there are now many different types of giving circles that exist around the globe. Some are small, informal groups of friends and family who come together to pool their resources for a common cause, while others are large, organized groups with a specific focus and structured giving processes. According to the Collective Giving Research Group, as of 2020 there were over 1,000 giving circles in the United States alone, and the giving circle movement continues to grow both nationally and globally.

What is a Giving Circle?

A giving circle is a form of collective philanthropy that brings together individuals who share a common goal of giving back to their community. Members pool their financial resources and then decide together how to allocate those funds to charitable organizations and causes that align with the group’s values and interests.

Why Join a Giving Circle?

Giving circles offer a unique and rewarding way to give back. By joining a giving circle, you have the opportunity to:

  • Amplify your impact: By pooling funds with others, you can make a larger donation than you might be able to on your own.
  • Build community: Giving circles provide an opportunity to connect with like-minded individuals who share your values and commitment to making a difference.
  • Learn and Grow: Through the collaborative process of selecting recipients, you can gain knowledge and insights into community needs and effective philanthropy.

How Our Giving Circle Works

Our giving circle operates on an annual basis. Members contribute each year, which is then pooled together to create a grant fund. Members then have the opportunity to nominate and evaluate potential nonprofit recipients, and collectively decide how to allocate the funds.

• Commit to an annual donation schedule, e.g. giving $150 once a year

  • As a member, you have the opportunity to nominate Marin-based nonprofit organizations that you believe would benefit from our collective giving. We encourage all members to participate in the nomination process and share their favorite causes with the group.
  • Once the nomination period ends, 5 nonprofits are selected to join us at our annual event where we convene as a group to hear firsthand about the amazing work being done in our community by these organizations
  • 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 organizations as well as the nonprofit community at large are increased

Join Us

We welcome new members who are passionate about making a difference in our community through collective giving. If you’re interested in joining, please contact us to learn more.

Thank you for visiting our website and for your interest in 100MARIN. Together, we can make a positive impact on the world around us.


In 2021, 100MARIN partnered with Center for Volunteer & Nonprofit Leadership (CVNL) to produce and administer the giving circle’s annual event. With CVNL’s support, 100MARIN is now positioned to grow its giving circle and raise more funds to increase community impact. With your participation, 100MARIN will be able to expand our reach, educate and engage more individuals about philanthropy and social change, and connect members to nonprofits, their communities, and each other.

At CVNL, we know that passion alone isn’t enough when it comes to creating strong nonprofits.That’s why we work with leaders and volunteers every day to help them build the skills and connections that can take their impact to the next level. When they are confident and prepared, our nonprofits will be better equipped to create healthy, happy, more equitable communities. We work daily to advance nonprofits and volunteerism by strengthening leadership, encouraging innovation, and empowering individuals in our communities.
