⚠ Checks disagree: 1 unverifiable, 2 confirmed, 1 partial

The source text confirms that Tom Brown is a co-founder of Anthropic and that Anthropic is a real organization. However, the source does not mention the specific start date of 2021-01 (January 2021). The record's claims about person, org, and role are confirmed, but the startDate field cannot be verified from this source. This is a partial confirmation because the key identifying information is correct, but one specific data field (startDate) is unverifiable from the provided text.

NoteWhile the source is from Anthropic's official company page and discusses the organization, it does not mention Tom Brown at all, nor does it provide a list of co-founders or founding team members. The only personnel information provided is the Board of Directors and LTBT Trustees. The absence of Tom Brown from this governance section does not contradict the claim (he may have been a co-founder but not currently on the board), but the source does not confirm the specific claim about Tom Brown being a co-founder or his start date of 2021-01. This is therefore unverifiable based on the provided source text.

NoteThe source text explicitly lists Tom Brown as one of the founders of Anthropic in the Wikipedia infobox, and confirms the founding year as 2021. The record claims Tom Brown is a co-founder at Anthropic with a start date of 2021-01 (January 2021). The source confirms both the co-founder role and the 2021 founding year. While the source does not specify the exact month (January), the year-level date matches and is consistent with the founding date. The role and organization are directly confirmed.
