Coefficient Giving (formerly Open Philanthropy) is an American philanthropic advising and funding organization. Its current CEO is Alexander Berger. As of June 2025, Coefficient Giving has directed more than $4 billion in grants across a variety of focus areas, including global health, scientific research, pandemic preparedness, potential risks from advanced AI, and farm animal welfare. It chooses focus areas through a process of "strategic cause selection" — looking for problems that are large, tractable, and neglected relative to their size.
