Source evidence
1 src · 1 checkNoteThe claim asserts that Holden Karnofsky is a Co-Founder & Co-CEO at Coefficient Giving with an end date of April 2024. However, the source text makes no mention of Coefficient Giving at all. The source discusses Karnofsky's roles at Open Philanthropy (which he left in July 2023) and his new position at Carnegie Endowment (starting April 29, 2024). The subject of the source is Karnofsky's career transitions, not his affiliation with Coefficient Giving. Since the source does not address Coefficient Giving and the record's end date (April 2024) aligns with when Karnofsky moved to Carnegie, the claim about Coefficient Giving cannot be verified from this source and appears to reference a different organization entirely. This is a subject mismatch: the source discusses Karnofsky's Open Phil and Carnegie roles, not Coefficient Giving.
