We envision a world where everyone has the opportunity to create positive, powerful change through collaborative giving.

Amplifier’s mission is to grow the movement of intentional, collaborative giving by building and sustaining giving circles inspired by Jewish values.

Giving circles are a powerful model of collective giving: people pool their resources and decide together where to allocate their funds. Being part of a giving circle amplifies the impact that an individual can have through their giving, empowering people to become more proactive, intentional givers who invest in change together.

Amplifier is the first concerted effort to network and create a field of giving circles inspired by Jewish values.

We create backbone infrastructure for the field by helping individuals and institutions to start and sustain giving circles, educating circle leaders and members about philanthropic best practices, linking circles to nonprofit organizations, and building values-driven communities rooted in Jewish wisdom. Amplifier enables thousands of people of all ages and giving levels to participate in an ever-growing number of giving circles around the world.  

See the impact we have made to date, and join us in this global movement by starting or adding an existing circle or registering a grant-seeking organization.
