| 2003 || || Prelude || {{w|Holden Karnofsky}} graduates from {{w|Harvard}} with a degree in {{w|Social Studies}}. Karnofsky would spend the next several years in the {{w|hedge fund}} industry.<ref name="GiveWell, or Give 'em Hell?">{{cite web|title=GiveWell, or Give 'em Hell?|url=https://metatalk.metafilter.com/15547/GiveWell-or-Give-em-Hell|website=metatalk.metafilter.com|accessdate=21 December 2017}}</ref>

| 2006 || || Prelude || {{w|Holden Karnofsky}} and Elie Hassenfeld, working at a {{w|hedge fund}} in {{w|Connecticut}}, set up an informal “charity club” with colleagues, to help them make informed decisions about their giving. Each person would pick a cause and then research the best charities working on that cause, evaluating them based on data and {{w|performance metric}}s. Hassenfeld and Karnofsky find this work so satisfying that it would ultimately lead them to create GiveWell.<ref>{{cite web|last1=Pitney|first1=Nico|title=That Time A Hedge Funder Quit His Job And Then Raised $60 Million For Charity|url=https://www.huffingtonpost.com/2015/03/26/elie-hassenfeld-givewell_n_6927320.html|website=huffingtonpost.com|accessdate=17 December 2017}}</ref>
