Our History

If you are like many people, you have independently given time and money to worthy charities over the years. In June 2016, a group of Bay Area women was presented an opportunity to do more. The impetus came from Nancy Clark, a Danville businesswoman and Board member of a Sonoma County non-profit. While reviewing that organization’s financials, she noticed a very generous grant from a new donor, Impact100 Sonoma.

Curious, Nancy learned more about Impact100’s all-volunteer, women-led philanthropic model. Inspired by the concept of creating a greater impact by pooling donations, she was amazed to find that no such organization existed in her area. So, she invited a small group of friends to hear from the women of Impact100 Sonoma. Afterward, she asked, “Are you interested in starting something similar here?” The response was an immediate “Yes!” Energized, the women got busy and Impact100 East Bay was born.

In September 2017, Impact100 East Bay proudly awarded its first grant. Five years later, our membership had grown sufficiently enough that we were able to award two grants for the first time. The equation is simple: the more members we have, the greater our ability to provide multiple grants that will assist those in need.

Immense unmet needs continue to challenge so many in Alameda and Contra Costa counties. Through the process of vetting grant applications, the women of Impact100 East Bay have come to know many local nonprofits that heroically serve others in our communities. Their contributions motivate us to do even more.

The Impact100 Model

The Impact100 model is readily available to all communities who wish to implement it. The model is designed to empower women to see themselves as philanthropists and to support transformational grant-making within their local communities, with a minimum grant of $100,000.

The model is simple.
More Members = More Grant Funds = More Impact

At Least 100 Women
Come Together

Each Woman
Donates $1,000

$100,000
is donated to a
Local Charity

Focus Areas

We provide nonprofit organizations with grants across five broad Focus Areas:

Arts & Culture

Education

Lisa Coelho - Making a Difference in the Environment

Environment, Recreation & Preservation

Family

Health & Wellness

How it Works

Impact100 East Bay members donate $1,000 annually. These donations are pooled and are subsequently awarded to qualifying nonprofit organizations in Alameda and Contra Costa Counties. Although the number and size of the grants we offer depends on our membership, our goal is to give incremental grants of $100,000 each year to support high-impact, transformational and sustainable projects.

Volunteer members serving on the Grant Committee thoroughly review grant applications. After a rigorous selection process, grants are awarded, based on the vote of the Impact100 East Bay membership, at the annual Grant Award Celebration. Every active member has one vote.

Grant recipients continue to partner with us throughout the duration of the grant. Their projects are monitored to ensure that desired outcomes are met. Through this process, our members have the confidence that their donations are used as intended and are making an impact.
