About

Harnessing the power of philanthropy to protect our future.

Expert-led and research-driven, we devise bespoke strategies that maximize 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.

Preventing the creation of bioweapons, securely and automatically

Today, anyone can order DNA from private companies, and it will only become faster and cheaper to do so in the coming years. Unfortunately, we don’t yet have a safe and efficient way to screen for DNA that could be used to manufacture a bioweapon. Current methods involve comparing potentially-dangerous sequences to a database of harmful sequences—effectively creating a public recipe book for bioweapons. SecureDNA aims to avert this danger. Scientists from MIT and Tsinghua University are creating technology that can quickly, automatically, and securely screen incoming DNA synthesis requests for potential threats. If successful, this project could make it far more difficult for malicious actors to create and release bioweapons, and could avert future pandemics.

Organisation for Economic Cooperation and Development
Organisation for Economic Cooperation and Development
Supporting global cooperation on extreme risks

The Organisation for Economic Cooperation and Development (OECD) is a leading forum for international coordination on expert policy advice and best governance practices. Their work supports 38 member countries—including the US and the EU—and non-member partners, including China. Their data analysis underpins work by the UN and the G20. The OECD is especially consequential for multilateral cooperation on artificial intelligence. They host the dominant international institution for AI governance, the AI Policy Observatory. We have an ongoing partnership with the OECD to support their work on existential risk policy across several directorates, including the Strategic Foresight Unit, the High-Level Risk Forum, the AI Policy Observatory, and the Secretariat on Bio-, Nano-, and Converging Technologies.

About
Taryn Jensen
Relationship Lead, Giving Pledge
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.

Hon. Andy Weber
Former U.S. Assistant Secretary of Defense for Nuclear, Chemical and Biological Defense Programs
Fascinating exposure to bright minds, intensive learning on massive challenges and opportunity for rigorous thinking about how to make the world a better place.
Stacey Kline
CEO of Otto Intelligence
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.
