Our Mission

One for the World’s mission is to scale the effective giving movement addressing extreme poverty.

One for the World’s theory of change: if we introduce young professionals to effective giving through our 1% Pledge, then we help scale the effective giving movement, because early choices inspire lifelong impact.

Our Values

Our Ways of Working

Our Story

One for the World was co-founded in 2014 by two then MBA students, Kate Epstein, and Josh McCann, at The Wharton School of the University of Pennsylvania in Philadelphia. 

During their program, Kate and Josh realized that their classmates were interested in learning about effective giving and high-impact nonprofit organizations but lacked the tools to take action. In order to empower their peers with the education and tools to evangelize effective giving on campus, the first One for the World chapter was established at Wharton and quickly expanded to include chapters on campuses around the world, including the United States, the United Kingdom, Australia, and Canada.

Our Approach

Every strategic decision we make aims to expand awareness of effective giving and increase the amount we funnel to our nonprofit partners yearly. We strongly encourage individuals to donate at least 1% of their income to our nonprofit partners that are on the ground fighting extreme poverty through cost-effective interventions. We have also invested in developing leaders across university campuses worldwide to organize One for the World chapters, train volunteers to recruit 1% Pledgers, coordinate events, and support various One for the World initiatives.

Our Partnership with GiveWell

One for the World partners and collaborates with GiveWell, the best-in-class nonprofit evaluator, to find outstanding giving opportunities for your pledged dollars. 100% of your pledged contributions go to the nonprofit partners featured on our website.

Disclosure: GiveWell, through its recommendations to the Open Philanthropy Project and the EA Global Health and Development Fund, used to act as a primary funder of One for the World’s operations but this ended in 2022. Learn more below:
