Strategic Pillars

We help donor members work together to improve grant making practice and boost collective impact around the following three areas:


Our members - both private foundations and public funders - recognize that governance challenges are complex and cross-cutting. They warrant a collaborative approach. TAI donors work together to strengthen accountability around the world. Learn more about each member below.


It’s only when people become aware, have pathways for action, and engage, that governments are held in account. Our three interconnected strategies focus on expanded participation, equitable resources and powerful engagement.

We work on a small number of big bets that strive toward transformative change in areas of profound concern, including the existential threats of climate change and nuclear risk, the challenges in the U.S. of criminal justice reform and in Nigeria of more effective and legitimate government services, and bringing more financial capital to the social sector.




TAI is not a grant-making organization itself – we are focused on enabling smarter donor approaches. TAI members represent a significant portion of global transparency and accountability funding. All are committed to being transparent about the wide ranging programming they support and why. Learn more about what our members fund.
