Coefficient Giving — key-person: sid_xVfFkFIk3Q

NoteThe source directly confirms that Elie Hassenfeld is a Board of Managers member at Coefficient Giving LLC. The claim correctly identifies him as a 'Board of Managers member (not a founder of Coefficient Giving)' which aligns with the source listing him as one of four board members. The additional context about his co-founding GiveWell and involvement with Open Philanthropy is not contradicted by the source (which focuses only on current governance). The opaque identifier 'sid_xVfFkFIk3Q' cannot be verified from this source but does not contradict the claim.
