Longview Philanthropy is a left-of-center organization that provides consulting services to grantmaking organizations. 1 Longview Philanthropy operates in the United Kingdom, and it operates in the United States under the name Longview Philanthropy USA. 2

Services provided by the organization include organizational compliance, how to prioritize grant recipients, consultations on high impact and long-term sustainable giving, and grant-recipient selection. 3


Longview Philanthropy was founded in 2018 by Natalie Cargill. 4 She has argued that the top one percent of society should donate 10% of their wealth to address existential challenges confronting the world. 5

Longview Philanthropy operates based on a “radical impartiality” philosophy, which reasons that people who exist today are equally as important as people who exist in the future, and as such grantmaking should be organized such that future generations continue to exist and have lives that are at least as good as the lives of people living today. 6

Policy Areas

The organization’s perspective on grantmaking has led it to develop six areas where it recommends grantmaking: public health, climate change, beneficial artificial intelligence (AI), public policy, nuclear disarmament, and global priorities research. 7

Public Health

Longview Philanthropy’s support for grantmaking in the public health sector includes funding research to prevent future pandemics similar to COVID-19 and research into vaccination for COVID-19 itself. For instance, Longview Philanthropy has funded Telis Bioscience (now Alvea), a pharmaceutical company that assisted in developing the “booster” vaccine for the Omicron variant of coronavirus. 8

Climate Change

Longview Philanthropy supported and recommended grantmaking to organizations that seek to increase the cost of energy produced through traditional sources through regulation and increasing taxpayer funded subsidies for weather-dependent energy producers. 9 The organization has supported funding to the Clean Air Task Force lobby and Carbon 180. 10

Nuclear Disarmament

Longview Philanthropy recommends grantmaking to anti-nuclear weapons programming through its Nuclear Weapons Policy Fund. 11 The organization states that support for the program will be used to bring more attention to range of nuclear risks that exist, risk reduction strategies such as disarmament and arms control agreements. 12 Organizations that Longview Philanthropy has identified and recommended for grantmaking include the Council on Strategic Risk, the Nuclear Information Project, and the Carnegie Endowment for International Peace. 13


Longview Philanthropy’s emphasize on long term change and quality of life for future generations leads it to oppose governmental policy making that is focused on five- or ten-year projects in favor of government funding and subsidization of long-term projects. 14

Organizations focused on long-term projects that Longview Philanthropy has recommended to receive grants include the Brookings Institution’s research program to identify existential risks from AI, 15 the left-of-center Centre for Long Term Resistance in the United Kingdom, 16 and direct policy making between Longview Philanthropy and the Organization for Economic Cooperation and Development (OECD) to promote international law and agreements in line with Longview Philanthropy’s worldview. 17


Longview Philanthropy USA was organized in the United States in 2024 and had not yet filed tax documents as of May 2024. 18 The organization lists Martin Crowley, Tom Crowley, Likith Govindaiah, Justin Rockefeller (the great-great grandson of John D. Rockefeller), Rafael Albert, and Ben Delo as funders of the organization. 19


Natalie Cargill is the founder and president of Longview Philanthropy. 20 Prior to joining the organization, she was a barrister at Serjeants’ Inn Chambers, a law firm in the United Kingdom. 21
