NoteWhile the source is from Anthropic's official company page and discusses the organization, it does not specifically mention Jared Kaplan or provide information about co-founders or their start dates. The Board of Directors listing does not include Jared Kaplan. The source material does not address the specific claims about Jared Kaplan's role, affiliation, or start date, making these claims unverifiable based on this particular source text.

NoteThe source text confirms all key fields: (1) person is Jared Kaplan, (2) org is Anthropic, (3) role is co-founder (explicitly stated in both the infobox and Notable employees section), and (4) startDate is 2021 (the company was founded in 2021). The record's startDate of '2021-01' (January 2021) is consistent with the source stating the company was founded in 2021, though the source does not specify the exact month. This level of precision is acceptable and does not contradict the claim.

Wikipedia explicitly lists Jared Kaplan among the founders

NoteThe source confirms three of four key fields: person (Jared Kaplan), org (Anthropic), and role (co-founder, plus Chief Science Officer). The startDate of 2021-01 is not addressed in the source text. The source indicates he co-founded Anthropic and has been there since, but provides no specific founding date or start month. This is a partial confirmation because the core identity and role are verified, but the temporal claim (startDate: 2021-01) remains unverifiable from this source.
