Who We Are

The ImpactAssets team brings several decades of experience in impact investing, innovative financial services, philanthropy and wealth management.


ImpactAssets: Empowering Access to Impact Investing

In 2010, ImpactAssets was spun out of Calvert Impact Capital in recognition of the growing need to increase flows of capital to the world’s greatest challenges.

The ImpactAssets Donor Advised Fund was created "of, by and for impact investors" to provide a flexible solution for the innovative and creative impact investing that philanthropists were seeking.

To this end, our north star has always been to provide unparalleled access to investment into top entrepreneurs and fund managers best positioned to tackle these challenges.

Since its inception, ImpactAssets has become the leading facilitator of direct impact investing within donor advised funds. Our portfolio represents more than 568 impact investment positions and $1 billion in assets. And we connect donors to a rotating offering of private impact funds, as well as a broader asset platform, all fully aligned to the UN Sustainable Development Goal framework.

We are also dedicated to field building through the ImpactAssets 50 database of private debt and equity fund managers, The ImpactAssets Handbook for Impact Investors and the ImpactAssets Issue Brief library.

Our success is testament to our highly engaged 1,000+ clients, strategic partners, board and staff. Impact is personal and we will continue to build out the ImpactAssets platform, expanding and collaborating to bring our community experience to life. We're proud of our progress, and recognize that we are at the tip of the iceberg in a dynamic and shifting world.

ImpactAssets is an independent 501(c)3 organization.
