Here are the Centre for Effective Altruism, 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 resources, technology, support and mentoring they need to do the most good.
