We are the Centre for Effective Altruism, and we're striving to solve the world's biggest problems. That's a challenging goal, and we believe that kind of long-term change cannot be solved by individuals alone. We need a global community of people tackling these issues.

Our team is dedicated to building a community of people who have made helping others a core part of their lives, and who use evidence and scientific reasoning to figure out how to do so as effectively as possible. We strive to provide the community with the resources, technology, support and mentoring they need to do the most good.

Here is our organizational chart as of July 2018.
