Core team


Benjamin Todd

Co-founder and Executive Director

In under three years with Ben's leadership, 80,000 Hours has grown from a student society, to an Oxford affiliated charity, featured on TED, the Washington Post, the BBC Today Programme and more. Ben has a 1st from Oxford in Physics and Philosophy, has published in Climate Physics and speaks Chinese. Before 80,000 Hours, he was the first undergraduate to intern as an analyst at a top investment fund. Rather than taking the job, he persuaded the Chairman to donate £60,000 to 80,000 Hours.


Prof. Will MacAskill

Co-founder and President

In 2009, Will co-founded Giving What We Can, a leading charity evaluator that has raised over $400m in pledged donations to effective charities and advised the UK government, World Bank, Oxfam among others. In 2011, he co-founded 80,000 Hours with Ben. Currently an Associate Professor of moral philosophy at Oxford, Will has pledged to give over half his income to charity, and is the author of *Doing Good Better*.

Peter Hartree

Technical Director

Peter studied Philosophy at the University of Sussex, graduating with a 1st and two awards for academic achievement. He was offered a Philosophical Quarterly bursary to study the M.Litt at St Andrews, but decided to postpone his return to academia in order to increase his social impact potential.

He is also co-founder of a coworking space in Reykjavík, Iceland.
