Join our Mission

Women have the power to transform their communities through collective giving. That’s where we (and you) come in!

Welcome to our membership page! Impact100 East Bay is a women’s collective giving organization with diversified backgrounds, ages and financial status and is open to all women ages 18 or older who live in, or who wish to help, the Alameda and Contra Costa County communities. By aggregating our members’ $1,000 donations, we are able to fund high-impact, transformational grants.

By combining our time, talents, and resources, we can make a greater impact strengthening communities in Alameda and Contra Costa Counties. The more members we have, the more grants we can give! For many of our Members, $1,000 represents sacrifice and intentional budgeting. Your entire $1,000 donation will go to a deserving nonprofit, voted upon by you, the Members, at our annual awards celebration each Fall.

We strive to have a membership that reflects the communities we serve. Our member goal is to have each woman feel empowered to bring their full, authentic selves to improve the lives of our local communities.

We have several events every year for you to connect with other like-minded philanthropic women, learn about our top community issues, hear from our Grant Recipients and their project’s impact, understand our current Grant Finalists and Celebrate our recipients! We also host optional Member Meetup events such as hiking, volunteering opportunities, and happy hours.

Our strategic goal is to provide 5 annual transformation Impact Grants (each $100,000) to make a significant difference in our local communities. This equates to 500 members each year!

Our membership objective is twofold:
1) to provide you with the best member experience, customized based on your interests and availability
2) connect you with other members and provide informational events to highlight community issues, progress from our previous grant recipients and impact to our community.

Scholarships Available

We offer limited scholarships to women who are interested in joining but cannot make the initial financial donation.

Our scholarship objectives are to find women passionate about philanthropy who are able to volunteer their time, broaden the diversity of our membership; and identify with our mission.

We have heard from our members that one of the reasons why they join is to connect with other like-minded women passionate about philanthropy, so we’ve developed several ways to do this: Volunteering, attending or hosting informal events in person and/or browsing through our member introductions located online!


Do you have a few hours of your time and/or financial resources you’d like to provide to help us grow our Impact?

Review our volunteer needs and then sign-up to volunteer any time throughout the year!
