Delivering unconditional cash directly to the world's poorest households via secure mobile transfers. 

Since 2009, GiveDirectly has delivered more than $580 million in unconditional cash transfers to families in need. These one-time cash transfers allow recipients to invest in what they need most and have been shown to improve their earnings, children’s school attendance, health, nutrition, and mental well-being.
 
GiveDirectly uses government data to target villages where most or all residents are living in extreme poverty, defined by the World Bank as earning under $2.15/day. In-country GiveDirectly staff enroll one member of each household in the entire village to receive a one-time transfer of about $1,000 USD sent in two installments using mobile money. Recipients can then withdraw the mobile funds as cash with local agents and use the funds to invest in what they need – whether it’s on starting a business, education, making their home safer/sturdier, healthcare, or livestock.
 
GiveDirectly uses rigorous experimental research (randomized controlled trials) to measure the impact of their unconditional cash programs and answer public policy questions, generating evidence on key design and implementation questions across varied contexts. You can find over 300 studies on the positive impacts of cash transfers in GiveDirectly’s Cash Research Explorer.

Many of our grants aim to address potential risks from advanced artificial intelligence and to build infrastructure and advocate for longtermist projects. However, we welcome applications related to long-term institutional reform or other global catastrophic risks (e.g., pandemics or nuclear conflict). We intend to support:

- Projects that directly contribute to reducing [existential risks](https://www.nickbostrom.com/existential/risks.html) through technical research, policy analysis, advocacy, and/or demonstration projects
- Training for researchers or practitioners who work to mitigate existential risks, or help with relevant recruitment efforts, or infrastructure for people working on longtermist projects

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.

Spritely Institute builds, researches, and standardizes networked technology which put people and communities first.


Centralized social media is harmful to society. We are building a gatekeeper-free decentralized system. Our mission is “social media done right”, to put people in control of their own identity and build the technology that would enable a shift to collaborative and intentional security models prioritizing active consent. To accomplish this, we will build a new architecture for the internet: removing the necessity of client-server architecture, replacing it with a participatory peer-centric model.

Spritely’s technology is being released as free and open source software aiming for multiple programming language implementations and eventual open standardization. All of our work, ranging from decentralized identity, peer-to-peer user agents, decentralized social networks, encrypted and portable storage, and distributed object programming infrastructure is being built to enable a gatekeeper-free path where users and content are not tied to a specific server.

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.
