I believe fungi research is our best hope for a healthy future Earth. In memory of Muriel Martin.

Hearing about this on Sam Harris's Podcast Making Sense made it clear that I should be donating too.

Good nutrition helps you avoid many health issues. An ounce of prevention works.

The Fungi Foundation is a global organization that works for the Fungi, their habitats, and the people who depend on them.

Launched in 2012, the Fungi Foundation is the first NGO dedicated to the fungi kingdom. Since its inception, it has achieved numerous milestones while dedicating itself to exploring the fungi world in view of increasing knowledge of their diversity, educating about their applications, and recommending public policy for their conservation. As part of our ongoing 3F initiative, the foundation played a key role in enabling Chile to become the first country in the world to include protection of fungi in its environmental legislation. More recently, the foundation proudly announced the Fantastic Fungi Education Curriculum, the world's first mycological set of courses designed for schools.

In short, the Fungi Foundation envisions a healthy planet in which Fungi are recognized, protected, and embraced as the interconnectors of nature; a mission that would be impossible without the essential support of our kind, engaged donors.

Developing the roadmap for a sustainable, secure, and just global protein supply 🧫🌱


Check out what your support makes possible at gfi.org/your-impact. 

The Good Food Institute (GFI) is a global network of nonprofit organizations developing the roadmap for a sustainable, secure, and just protein supply. Industry alone will not meet this challenge at the scale or speed we need. GFI is accelerating the transformation of the food system by identifying solutions and mobilizing resources to make alternative proteins the default way meat is made.

GFI is a network of nonprofits around the world strategically based in the most critical economies for alternative protein advancement. In Asia, Europe, Brazil, India, Israel, and the U.S., GFI’s teams are mobilizing the international community to use markets and technology to replace harmful practices with ones that are better for the climate and biodiversity, for food security, and for global health.

GFI’s Focus
As a nonprofit, GFI is uniquely positioned to accelerate the transition to alternative proteins by focusing on three programmatic priorities:

-Cultivating a strong scientific ecosystem | GFI’s science and technology teams map out the most neglected areas that will allow alternative proteins to compete on taste and price. GFI meets these challenges by developing open-access research and resources, educating and connecting the next generation of scientists and entrepreneurs, and funding research that benefits alternative protein development across the sector. 

-Influencing policy and securing government funding | GFI’s policy teams ensure that alternative proteins are a part of the policy discussion around climate change mitigation and global health. In every region where GFI has a presence, teams advocate for government funding and incentives to transition to alternative proteins and are paving the way for the approval of novel proteins such as cultivated meat.

-Ensuring industry prioritizes alternative proteins | GFI’s corporate teams are creating a transformation of our global meat supply. GFI works to replicate past market transformations by showing companies of all sizes, from startups to multinational corporations, how alternatives to animal products can be profitable while meeting environmental, social, and governance goals.

Reimagining meat
The very real threats of climate change, global food insecurity, antibiotic resistance, and pandemics require us to imagine a different future of food. Alternative proteins are the solution that will securely and sustainably feed the world.

GFI’s global community of scientists, policy experts, and corporate specialists are creating a world where alternative proteins are no longer alternative.

Sentinel transforms pandemic prevention and response through cutting-edge technology, global collaboration, and local empowerment.

Infectious disease outbreaks have caused more illness, death, and economic loss than any other crisis in history. Pathogens kill millions of people each year and hit the most vulnerable communities the hardest. They go further—exposing and exploiting the deepest cracks in our societies and the risks are rising. 

 The forces driving pandemics are accelerating. Climate change is increasing human exposure to pathogens through animals and insects. Habitat encroachment and industrial agriculture are raising the risk of spillover. Global trade and travel speed disease spread, while conflict and instability weaken health systems. New biotechnologies pose engineered threats that current systems cannot detect. Over the past decade, the number of epidemics has grown by 20% worldwide. Between February and June 2025 alone, more than 70 outbreaks were reported across Africa. Yet global readiness is faltering. In the past year, U.S. investments in frontline health systems and disease surveillance have been sharply reduced. Funding cuts have disrupted networks and delayed the deployment of critical tools, especially in regions most vulnerable to outbreaks. Health programs across West and Central Africa now face rising threats with fewer resources and limited external support, leaving the world more exposed- with some experts estimating the probability of a pandemic in the next decade to exceed one in four.
 
Amid these mounting challenges, we stand at a historic moment of possibility. Sentinel, a pandemic early warning prevention and response program, is built to meet this moment: a locally led, technology-enabled model for proactive public health, integrating diagnostics, data, and training to stop outbreaks before they spread. 

Sentinel is an outbreak surveillance framework, designed to detect pathogenic threats in real-time and prepare the global community to stop diseases before they spread. It brings advanced science to the frontlines through a next-generation pandemic prevention system built around three core pillars. DETECT delivers rapid diagnostics and genomic surveillance. CONNECT integrates laboratory, clinical, and genomic data into real-time insights. EMPOWER invests in training, infrastructure, and institutional capacity so countries can lead their own outbreak responses.

DETECT: Timely diagnostics and sequencing are essential for early outbreak detection and effective response. Yet these capabilities remain limited in many LMICs, even for high-priority pathogens like Lassa, Ebola, and Marburg. Too often, health systems act only after outbreaks are widespread, costing precious time and lives. Sentinel’s DETECT pillar delivers speed, affordability, and accessibility through a tiered approach to diagnostic design and implementation.

CONNECT: Fragmented systems delay response and allow outbreaks to spread unchecked. When data are siloed, public health leaders lose time and visibility, undermining containment efforts. In contrast, integrated systems support faster, more effective action. Sentinel’s CONNECT pillar builds the digital backbone for outbreak response. Through interoperable dashboards and analytic platforms, it streamlines data flow, strengthens each stage of detection, analysis, and control, and enables real-time decision-making.

EMPOWER: Building local leadership and scientific capacity is central to Sentinel’s mission. Although over 60% of emerging infectious diseases originate in Africa and Asia, fewer than 10% of African countries had genomic surveillance at the start of COVID-19. Africa faces a shortfall of more than one million health workers, including critical gaps in genomics and data science. Sentinel’s EMPOWER pillar builds sustainable, locally led outbreak response by investing in people and communities. It enables local experts to detect and respond early with solutions grounded in context, shortening the path from innovation to public health practice and building resilient systems from within.

The foundation for Sentinel was laid over two decades through a 20-year partnership between Prof. Christian Happi, a Nigerian infectious disease expert, and Prof. Pardis Sabeti, a U.S.-based computational geneticist. Over the years this collaboration has established operational programs in Nigeria and Sierra Leone that connect health workers in rural clinics and hospitals with national and international public health leadership. **To date more than 3,000 public health workers from 53 of 54 countries in Africa** have been trained through Sentinel’s approach.

Sentinel-supported teams have enabled early detection and rapid response to Marburg, mpox, Lassa, dengue, and COVID-19, providing critical data to inform government action. 

COVID-19: Sentinel rapidly expanded genomic and diagnostic capacity across Africa, establishing pipelines with national partners. In March 2020, IGH sequenced Africa’s first SARS-CoV-2 genome within 72 hours of sample receipt. Sentinel supported testing for over 30 million people, deployed SHINE and CARMEN technologies, and led genomic surveillance in 26 countries. This work helped identify one of the first globally recognized variants of concern. Sentinel also trained scientists from 53 African countries, strengthening long-term preparedness. The Sentinel team also led one of the largest diagnostic and sequencing centers in the U.S. and supported global data sharing and informatics efforts.

Mpox: In 2023, Sentinel traced an mpox outbreak in Nigeria to oil workers in Rivers State, guiding the NCDC’s targeted vaccination strategy. Sentinel also hosted a three-week genomics bootcamp that trained regional professionals in real-time sequencing and analysis. Genomic data revealed sustained human transmission of the West African subtype, with signs of adaptation and rising pandemic potential. When an outbreak emerged in Sierra Leone in 2024, local public health teams, supported by Sentinel, initiated sequencing and shared real-time data. Analysis identified a new highly transmissible G.1 variant spreading beyond previously affected groups. Sentinel tools and team members remain central to guiding the national response.

 Marburg: In 2024, Sentinel supported the Rwandan government during a Marburg outbreak in Kigali. IGH provided outbreak reconstruction and real- time sequencing, while Prof. Happi co-chaired the national scientific response. The outbreak was contained at 66 cases, with the case fatality rate reduced to 22%, far below historical averages.

Building off of these successes, Sentinel is poised for its next phase: deepening national integration, expanding its reach, and advancing a globally transferable model for pandemic prevention. We will achieve full national implementation in Sierra Leone and move toward this in Nigeria, embedding surveillance into national systems and incorporating a One Health approach that addresses climate-linked and zoonotic threats. Expansion will continue to Senegal, Rwanda, and the Democratic Republic of Congo, where strong partners and readiness are in place. In parallel, we are globalizing Sentinel’s tools, data platforms, and training programs to create a lasting framework for pandemic prevention.

Sentinel will help millions benefit from earlier detection, faster response, stronger systems, and a globally connected early warning network. This is the moment to transform pandemic prevention and safeguard global health security for generations to come.

There will be another pandemic virus in our lifetimes—it may already be here, but our work is about more than stopping disease outbreaks. By empowering people and equipping them with the tools, the system, and the knowledge needed, we create strong and resilient communities for generations to come. Sentinel is about partnership, solidarity, and most importantly, hope!

That's why we believe that with you, we can make an impact.

Allies Against Slavery builds platforms and partnerships that accelerate data-driven solutions to human trafficking. 

Human trafficking is a hidden problem that thrives in the shadows of society. Myths and misconceptions are pervasive, and data is unreliable. As a result, victims aren’t identified, traffickers aren’t prosecuted, and solutions aren’t data-informed or well-coordinated.

But that is changing. Allies Against Slavery harnesses data to illuminate and eradicate human trafficking. Our tools help allies in the fight to identify victims, coordinate care, and take informed action. 

Our vision is clear: to ensure that every community across the United States has the data it needs to combat and prevent human trafficking. But we cannot achieve this vision alone. We need to leverage innovative, data-driven solutions and forge crucial partnerships to shine a light on trafficking and build a future where freedom and dignity are secured for all. We invite you to join us in this important mission.

We aim to mitigate catastrophic risks from transformative AI, which we believe could be developed in the next few decades.



The AI Risk Mitigation Fund (ARM Fund) is a non-profit fund making grants in technical research, policy, and training programs for new researchers to reduce catastrophic risks from advanced AI.

We are focussed on the following three areas.

Technical AI alignment research
Technical research can uncover dangerous capabilities before it’s too late, or enable designing future AI systems with enhanced interpretability, steerability, and possibility for human oversight.

Policy
Policy work aims to ensure that government regulation and corporate standards appropriately guard against catastrophic risks.

Training for new researchers
Investment has poured into AI capability development, yet strikingly few researchers are working on key problems in AI safety, particularly outside major industry labs. Grants in this area aim to bring new talent into the AI safety field.

Our mission is to mitigate catastrophic risks from transformative AI, which we believe could be developed in the next few decades.

Our team and history
Our team works hard to ensure you make the most effective donations possible. We have substantial experience managing large donations securely, professionally, and flexibly. We've collectively overseen tens of millions of dollars worth of donations to nonprofits based on careful analysis of their impactfulness and ability to use new funding.

What you can expect if you donate
When we receive a donation designated for the ARM Fund, we grant 100% of the value of the donation (minus any fees charged by payment processors) to organizations and individuals recommended by our team of expert grantmakers.

The ARM Fund does not take any fees from donations before the distribution (we fundraise separately for our overhead costs, which include wages for our grantmakers).

The ARM Fund will likely have a partially overlapping group of applicants as the Long-Term Future Fund. So while 100% of your donations will go directly to AI safety projects under the ARM Fund, your donations will likely have an indirect effect in freeing up some of LTFF’s other resources to be spent on other existential security interventions, including both in AI safety and in other LTFF focus areas like biosecurity.

Donors will have the option to join our quarterly mailing list tracking updates in AI safety, listing our grants, and more.

100% of your donation is tax-deductible to the extent allowed by US law. Your donation is made to Every.org, a tax-exempt US 501(c)(3) charity that grants unrestricted funds to Effective Ventures Foundation USA, Inc. on your behalf. As a legal matter, Every.org must provide any donations to Effective Ventures Foundation USA, Inc. on an unrestricted basis, regardless of any designations or restrictions made by you.

Aquatic Life Institute is a 501(c)(3) non-profit focused on reducing the suffering of aquatic animals in the global food system.

Aquatic Life Institute (ALI) was founded in 2019 to address the critical and often overlooked issue of aquatic animal welfare. Recognizing that aquatic animals are the most exploited group of animals worldwide yet remain largely unprotected, ALI set out with a mission to drive systemic change and elevate aquatic animal welfare as a priority in global food systems.

Our theory of change is rooted in the belief that by influencing key stakeholders and decision makers, advancing policies, and fostering collaboration, we can drive systemic transformation for billions of aquatic animals. 

Building on this foundation, ALI has emerged as a thought leader, advocating for tangible improvements across the seafood supply chain. By engaging with key stakeholders, including corporations, certification schemes, and policymakers, we work to ensure that aquatic animals trapped in the food system receive the attention they deserve in decision-making processes relating to sustainability and food systems. 

ALI’s work is driven by evidence-based strategies and collaboration. This approach has earned ALI widespread recognition, including a 2024 Top Charity recommendation from Animal Charity Evaluators (ACE). This endorsement solidifies ALI’s position as one of the most effective organizations in the world advancing aquatic animal welfare.

Phare Bio is using AI/deep learning to discover novel classes of antibiotics to address a looming crisis in antibiotic resistance.

Phare Bio is an ambitious social venture using novel AI and deep learning approaches to antimicrobial development in collaboration with Professor Jim Collins at MIT, a founder of the field of synthetic biology. Phare is a recipient of the Audacious Project, a collaborative funding initiative between TED and other non-profits to unlock social impact on a grand scale. 

The rapid evolution of antibiotic-resistant bacteria and a dwindling discovery pipeline have resulted in an antimicrobial resistance (AMR) crisis. Today, according to the Centers for Disease Control and Prevention, someone in the U.S. acquires a resistant infection every 11 seconds; every 15 minutes someone dies as a result of one. Covid-19 has only highlighted the urgency with approximately 15% of hospitalized patients suffering from bacterial co-infections. There is a critical need for new antibiotics, and yet, pharmaceutical and biotechnology companies have largely abandoned the space in favor of more lucrative markets. 

Phare Bio launched in 2020 to tackle this critical unmet need with the latest advances in machine learning to develop entirely novel antibiotics. Integrating world-class expertise and decades of experience in artificial intelligence (AI), bioengineering, and life sciences, Phare is targeting the world's most deadly pathogens, such as Acinetobacter and Pseudomonas, with the goal of developing seven novel classes of antibiotics in seven years.

Prevention, control and treatment of malaria and other communicable diseases among vulnerable populations.

Malaria Consortium US, Inc. (MC-US) is a registered 501(c)(3) public charity and shares the mission of Malaria Consortium, a globally recognized organization committed to reducing deaths and illnesses caused by malaria and other preventable and treatable diseases across Africa and Asia.

Our mission is to save lives and improve health in Africa and Asia through evidence-based programs that tackle malaria and other priority diseases while advancing universal health coverage (UHC). In the US, we build partnerships with foundations, donors, and philanthropic organizations to ensure that every contribution makes a lasting impact for those most in need.

As a leader in malaria control and elimination, our work focuses on interventions such as seasonal malaria chemoprevention (SMC), malaria vaccines, disease surveillance, and integrated child health services. We work in collaboration with governments, communities, and health systems to improve access to essential healthcare and strengthen delivery of services in underserved and hard-to-reach areas.

As a leader in interventions such as chemoprevention and vector control, we rely on evidence and our expertise to deliver established interventions, influence other effective interventions and guide new strategies to reduce the burden of malaria, pneumonia, dengue, malnutrition and diarrhea. We work with communities and all levels of the health system to improve access to and demand for primary healthcare services and overall quality of care.

Our tailored interventions seek to improve equity by providing quality, affordable health services to marginalized populations (particularly women and girls and those living in hard-to-reach areas). To ensure barriers to achieving UHC are addressed and to encourage sustainability, we work closely with governments to integrate our programs within existing health systems and structures in the countries in which we work.

We promote disease surveillance as a core intervention to engage communities to improve the quality and accessibility of routine health information by using digital tools and approaches that strengthen the linkages between case-level data and national health information systems. We combine capacity development at community level with the use of innovative tools and platforms to enhance local capabilities to interpret and use these data most effectively.

All of our work is informed by our core values: accountability, integrity, dignity and equity.

Protecting free expression and enabling secure global communication through open source privacy technology.

Long before we knew that it would be called Signal, we knew what we wanted it to be. Instead of teaching the rest of the world cryptography, we wanted to see if we could develop cryptography that worked for the rest of the world. At the time, the industry consensus was largely that encryption and cryptography would remain unusable, but we started Signal with the idea that private communication could be simple.

Since then, we’ve made some progress. We’ve built a service used by millions, and software used by billions. The stories that make it back to us and keep us going are the stories of people discovering each other in moments where they found they could speak freely over Signal, of people falling in love over Signal, of people organizing ambitious plans over Signal. When we ask friends who at their workplace is on Signal and they respond “every C-level executive, and the kitchen staff.” When we receive a subpoena for user data and have nothing to send back but a blank sheet of paper. When we catch that glimpse of “Signal blue” on a metro commuter’s phone and smile.

However, we’ve always wanted to do much more, and our limitations have often been challenging. Over the lifetime of the project, there have only been an average of 2.3 full-time software developers, and the entire Signal team has never been more than 7 people. With three client platforms to develop, a service to build and run, a growing list of integrations to assist with, and millions of users to support, that has often left us wanting.

Even so, Signal has never taken VC funding or sought investment, because we felt that putting profit first would be incompatible with building a sustainable project that put users first. As a consequence, Signal has sometimes suffered from our lack of resources or capacity in the short term, but we’ve always felt those values would lead to the best possible experience in the long term. The Signal Foundation completes our vision of Signal operating as part of a full 501(c)(3).
