Animal Charity Evaluators helps people help the most animals.

Animal Charity Evaluators (ACE) is a 501(c)(3) nonprofit registered in the United States with a globally distributed team dedicated to impactful animal advocacy. Our mission is to find and promote the most effective ways to help animals. We work toward that mission by evaluating charities, sharing our findings, awarding grants to organizations and promising projects, and fundraising for our recommended charities and grantees. Our organization opposes all systems of oppression and recognizes that they are connected and mutually reinforcing. Ultimately, our vision is a world in which no individual is given less than full moral consideration on the basis of any morally irrelevant feature of their identity, including species membership.

ACE is proud to be considered a leader in the effective animal advocacy movement. Our research comparing the different approaches to reducing the suffering of animals has led to rigorously reviewing charities that work to end factory farming and create meaningful change for farmed and wild animals. Through our Recommend Charity Fund, we have raised and distributed $8.1M to our effective recommended charities. Our Movement Grants program has awarded $5.3M to promising animal advocacy projects around the globe. Since we began tracking this metric in 2014, we estimate that ACE has helped to influence nearly $60M within the animal advocacy movement.

Thanks for helping ACE help animals!

Animal Charity Evaluators

A new initiative to advance forecasting and epistemics for the aim of improving the long term future of humanity.

We research systematic practices to specify and estimate the most important parameters for the most important or scalable decisions. Research areas include forecasting, epistemics, evaluations, ontology, and estimation. We emphasize technological solutions that can heavily scale in the next 5 to 30 years.

We believe that humanity’s success in the next few hundred years will lie intensely on its ability to coordinate and make good decisions. If important governmental and philanthropic bodies become significantly more effective, this will make society far more resilient to many kinds of challenges ahead.
