"Future generations are the ultimate unrepresented constituency" 

- Lord Martin Rees, Astronomer Royal and Effective Giving UK contributing author. 


Our vision is a world in which the interests of future generations are protected, and where the long-term potential of humanity is preserved. 


Our mission is to harness the power of philanthropy to help us get there.



We find exceptional funding opportunities to protect future generations, and recommend them to our network of major donors. Every recommendation we make is informed by our extensive expert network, and we work closely with the University of Oxford.


We bring together the growing community of philanthropists who champion this cause in both their giving and their advocacy. Our events and publications connect the donors, researchers and grantees who make long-term change possible.

We currently advise donors in Europe, North America and Asia, whose giving capacity ranges from $1 million p.a. to the majority of $1 billion. For all types of donors at all stages in their giving journey, we offer in-depth 1-on-1 strategy sessions; intellectual deep-dives with experts in fields such as nuclear security and pandemic preparedness; as well as grant processing, due diligence, and impact assessment. 


All of our services are entirely free-of-charge, and we are always keen to connect our donors with independent expertise. Our operational expenses are generously covered by a small number of professionals aligned with our mission, and these donors do not influence the direction of our work.

We are also excited to announce our upcoming re-name to Longview Philanthropy. Our soon-to-be name reflects our deep commitment to maintaining a focus on long-term issues.


We are a mission-driven organisation: All of our senior staff and advisors have given in their personal capacity to the areas we recommend, and have signed the Giving What We Can Pledge.
