“When I started giving to effective charities, I struggled because I didn’t want to give less to my favourite organizations. Giving Multiplier is a platform that solves this problem by directing some of your giving to effective charities and adding matching funds in order to maximize the collective impact of our charitable gifts!”

“Is there a special charity you want to give to because you have a personal connection, but at the same time you know that, dollar-for-dollar, it won’t do nearly as much good as other charities you could give to? Amazingly, you can do both, and still not give less to the most effective charity you can find! Check out Giving Multiplier!”
Peter SingerProfessor of Bioethics, Princeton University
and author of The Life You Can Save -
“Giving Multiplier is a brilliant tool for anyone who believes in doing good effectively but doesn’t want to abandon their personal connection to specific causes. It helps you do what is simultaneously meaningful to you and highly impactful.”

Our impact
since Nov. 2020
GiveDirectly
GiveDirectly lets you send money directly to the world’s poorest, no strings attached. Hundreds of academic studies show cash transfers can boost income, health, education, gender equity, local economic activity, and more. In the last decade, we’ve reached over 1.6 million people in poverty across 14 countries, largely via simple banking technology called mobile money.
Malaria Consortium
Malaria Consortium delivers a highly effective community-based intervention to prevent malaria infections in children in areas where the malaria burden is high and transmission is seasonal. Their seasonal malaria chemoprevention (SMC) program ensures those most at risk receive preventative medication during the peak malaria season.
Against Malaria Foundation
The Against Malaria Foundation provides funding for long-lasting insecticide-treated net (LLIN) distributions (for protection against malaria) in developing countries. Insecticide-treated nets prevent malaria and are inexpensive — about $5 per net. There is strong evidence that distributing LLINs reduces child mortality and malaria cases.
Evidence Action's Deworm the World
Deworm the World provides technical assistance to governments to deliver deworming treatments to children where they already are: schools and communities. Since 2014, Deworm the World has helped deliver over 2 billion treatments to children for less than $0.50 per child per year on average. More than 895 million children, mostly in poor communities, are at risk for parasitic worm infections that can cause anemia, malnourishment, and hinder mental and physical development, affecting school attendance.
Helen Keller Intl
Helen Keller International (Helen Keller) supports programs focused on reducing malnutrition and averting blindness and poor vision. Experts consider Helen Keller's work on vitamin A supplementation (VAS) in fourteen countries across sub-Saharan Africa to be particularly effective. Helen Keller Intl provides technical assistance, engages in advocacy, and contributes funding to government-run VAS programs. By providing essential Vitamin A to children aged 6 to 59 months, the program strengthens immune responses, significantly reducing the risk of blindness, disease, and death.
New Incentives
New Incentives runs a conditional cash transfer (CCT) program in North West Nigeria which seeks to increase uptake of routine immunizations through cash transfers, raising public awareness of the benefits of vaccination and reducing the frequency of vaccine stockouts. A randomized controlled trial (RCT) of New Incentives' program found strong evidence that the program increases vaccination rates.
The Good Food Institute
The Good Food Institute works in an underutilized but critically important area by promoting and developing competitive alternatives to animal-based meat, dairy, and eggs. They provide support in a variety of ways to cellular agriculture and cultured meat companies, including building relationships with distributors and retailers and driving R&D of the products.
The Humane League
The Humane League is a global animal protection nonprofit that exists to end the abuse of animals raised for food. Through corporate negotiations, grassroots activism, and policy work, they drive meaningful change across the food industry that reduces the suffering of billions of farmed animals. Their evidence-based approach and dedication to institutional and individual change have made them one of the most effective animal protection organizations worldwide.
Clean Air Task Force
Clean Air Task Force (CATF) is a global nonprofit organization working to safeguard against the worst impacts of climate change by catalyzing the rapid development and deployment of low-carbon energy and other climate-protecting technologies. Their campaigns focus on reducing the air pollution caused by coal and gas-fired power plants; regulations of methane emissions from oil and gas, agriculture, and waste; and pushing the policy and regulatory changes needed to advance next-generation climate technologies like advanced nuclear energy, fusion energy, and superhot rock geothermal.
Johns Hopkins Center for Health Security
The Center for Health Security at Johns Hopkins advances policy, science and technology to protect people’s health from epidemics and disasters and ensure that communities are resilient to major challenges. The Center conducts research to prevent and prepare for GBCRs to enhance global health security.
