About

Harnessing the power of philanthropy to protect our future.

Expert-led and research-driven, we devise bespoke strategies that maximise the impact of your giving.

How We Work

We work with donors in every stage of their giving journey, from brand new philanthropists to seasoned leaders of effective giving. Depending on your particular needs, we can introduce you to experts on the world’s largest and most neglected issues, bring you into our curated learning sessions on the principles of effective giving, or simply meet you in the trenches and share our current grant opportunities and the reasoning behind them. Everything we do is always completely free of charge or commission.

A sample donor experience:

  1. We introduce you to the principles of effective giving through an individual seminar that explores how giving today can have an outsized effect on the decades, centuries, and millennia to come. We tailor each session to your needs, but frequently cover: the role of philanthropy in moral progress, why we should be optimistic about our ability to make an enormous difference, our radically impartial and reason-driven approach to giving, how we prioritise between different causes, what solutions to global problems might look like, and how best to take action given the current philanthropic landscape.
  2. We introduce you to world-class experts in key cause areas who can answer any questions you have about their field. We are committed to clarity and transparency about our reasoning and research. While some of our philanthropists prefer to be more hands-off, you will be given the opportunity to know as much as we do about why we believe our grants are high-impact, and how that impact is achieved.
  3. At the conclusion of this learning process, which can last anywhere from days to months, we will create a bespoke portfolio of grant recommendations. See our grantmaking page for more details on our process and focus areas. If this portfolio is approved, we do everything necessary to facilitate the transfer of the grant, including due diligence and processing.

For established donors who are already on board with our approach:

  1. If you prefer to cut to the chase, we can immediately begin investigating grants that suit your needs. We share our recommendations and reasoning as soon as possible in written reports.
  2. We also invite donors to contribute directly to the Longview Philanthropy Fund, which allows us to make timely grants to the very best opportunities as they arise. All contributors to the Longview Philanthropy Fund are provided with reports every six months. These reports detail the grants we made during that period, our reasoning for those grants, and major updates to our grantmaking programmes.

BIOTECHNOLOGY PROFESSOR AT MIT AND LEADER OF SECUREBIO
Kevin is an associate professor at MIT’s Media Lab, where his research lab focuses on advancing biotechnology safely.

Recognizing the implications of this technology for the environment, he quickly became a public advocate for safety and transparency in the field of biotechnology to reduce the risk of accidents and misuse. Kevin now leads SecureBio, a nonprofit that incubates projects working to prevent and prepare for extreme pandemics.

Supporters

Our operational costs are fully funded by the below group of philanthropists. We are deeply grateful for their support – it is what allows us to provide all of our funding recommendations, research and work free-of-charge. While our funders share our mission, they have no influence over any aspect of our work, including our grant recommendations.

Current funders include Martin Crowley, Tom Crowley, Likith Govindaiah, Justin Rockefeller, Rafael Albert and several private philanthropists and foundations. Historical funders include Ben Delo.

These people began warning us of the risk posed by pandemics well before anyone had ever heard of COVID. That risk is higher now than it ever has been. To prevent the next pandemic - which could be far more devastating than any we have yet experienced - philanthropists should pay close attention to what the team at Longview has to say.

Stacey Kline

If all goes well, humanity has a vast future ahead of it — but very little of our philanthropy takes the scale of this future seriously. That’s why I am so excited about Longview Philanthropy. They really get it, and are finding opportunities for lasting impact.
