We need to scale up new effective charities. I have a ton of respect for their approach, especially after hearing that they shut down their No Lean Season after collecting evidence that showed lower impact than hoped-for: https://www.vox.com/future-perfect/2019/6/7/18654620/evidence-action-no-lean-season-givewell

Evidence Action scales evidence-based and cost-effective programs to reduce the burden of poverty. 

Evidence Action was founded in 2013 to address a big gap in the fight against global poverty – many of the most promising interventions are either implemented at a very small scale, or not at all. We set out to address this gap by building programs that would scale evidence-based and cost-effective interventions, leading to significant improvements in quality of life for hundreds of millions of people.

Our model worked. Since then, our interventions have reached more than 530 million people. This success is achieved through the dedication and talent of our staff, the hard work of our partners, and the commitment of our supporters.

Our Accelerator is the engine for our new program development. To find the most cost-effective solutions in the world, we explore untapped opportunities with the greatest potential for impact. Through a rigorous process, we test groundbreaking health and development interventions, selecting those with a proven ability to reduce the burden of poverty at scale. This focus allows us to maximize the impact made for every single dollar invested.

**Programs:**

**Safe Water Now**

We provide sustained safe water access to communities through water treatment – one of the most cost-effective ways to prevent childhood illnesses and death. Safe Water Now programming in Kenya, Uganda, Malawi, and India uses innovative, low-cost approaches like chlorine dispensers and automatic in-line chlorination. With local government and community buy-in, we reach nearly 10 million people with safe water access and have saved the lives of more than 15,000 children under 5 years old. Now, we are scaling in partnership with the Government of India to reach tens of millions more.

**Deworm the World** 

We help improve children's health, education, and long-term wellbeing by treating parasitic worm

infections at schools. In partnership with governments in Kenya, Nigeria, India, and Pakistan, Evidence Action designs, scales, and sustains cost-effective mass deworming programs. Since 2014, Deworm the World has helped governments deliver 2 billion deworming treatments to children, dramatically reducing worm prevalence and collectively increasing economic productivity by an estimated $23 billion USD.

**Equal Vitamin Access**

We combat the leading cause of childhood malnutrition and disability in low- and middle-income countries by helping to deliver essential supplementation. Equal Vitamin Access provides end-to-end support to governments in India and Malawi to address anemia by leveraging our school-based deworming platform to offer iron and folic acid supplementation cost effectively. In 2023 alone, our program reached 35.8 million children with weekly treatments, giving them a

better chance to develop into strong, healthy adults.

**Syphilis-Free Start**

We safeguard the health of pregnant women and their unborn children by enabling access to low-cost syphilis screening and treatment as part of prenatal care. We partner with governments in Liberia, Cameroon, and Zambia to prevent disability, neonatal

mortality, and stillbirths resulting from congenital syphilis. Syphilis-Free Start’s timely detection and treatment prevented 2,300 adverse outcomes such as blindness, neurological issues, and hearing loss between 2021 and 2023, including 1,300 lives saved.
