Summary
- GiveWell CEO advocates for data-driven charity.
- Early career in Talmud study informed rigorous thinking.
- Hedge fund experience honed skills in seeking truth.

Elie Hassenfeld, CEO of GiveWell, advocates for a more rigorous and transparent approach to charitable giving.

GiveWell applies this analytical framework to philanthropy, identifying charities that demonstrably save and improve lives at the lowest cost.
