Our Partners

We partner with high-impact organizations to efficiently reach vulnerable populations by layering ORSZ provision onto existing health interventions.

Sustainable impact requires deep integration with local health systems. We work in close coordination with the Nigerian health authorities at every level to align with national strategies and ensure long-term community ownership.

Our Advisors

Dr Zachary Wagner

Dr Zachary Wagner is Associate Professor (Research) of Economics at the University of Southern California, known for his expertise in global health policy and innovative field experiments. Within his research portfolio spanning health financing, behaviour change, and disease prevention, he led a key randomized controlled trial in Uganda, evaluating several community health worker distribution models for ORS and zinc to treat diarrhoea in children under-5, identifying significant potential for increased ORS and zinc uptake.

Dr Simon Ling

Simon is the Executive Director at High Impact Medicine, a non-profit organization empowering doctors to apply their careers and giving to highly impactful causes. He has 25 years experience as an academic paediatric gastroenterologist and leader at The Hospital for Sick Children and the University of Toronto. He undertook clinical research studies of infant nutrition and zinc supplementation in South Asia, and of hepatitis B and other liver diseases in North America. He contributed to the development of clinical practice guidelines, including the 2024 World Health Organization guideline for hepatitis B.

Jane & Simon Berry

Jane and Simon Berry are founders of ColaLife and a driving force behind the ORS and Zinc Co-pack Alliance (ORSZCA). ColaLife catalysed huge improvements in ORS+zinc usage rates in Zambia through both the private and public sectors. This success led to engaging the WHO on the addition of co-packaged ORS+zinc to the Model Essential Medicines List, and later building ORSZCA to convene stakeholders with the aim of accelerating the uptake of the co-packaging recommendation.

Patrick Stadler

Patrick is co-founder and chair of the board of GiveWell-recommended nonprofit, New Incentives. He helped New Incentives scale from to over 100,000 users for their vaccination programme in Nigeria.

Joey Savoie

Joey co-founded Charity Entrepreneurship in 2018 and the organisation has since helped launch numerous high-impact nonprofits through its Incubation Program.

Joey previously founded and led Charity Science Health, a global health charity sending SMS reminders for immunisation appointments in India.
