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.

NoteThe source confirms Tom Brown's role as co-founder of Anthropic. However, the source does not provide a specific start date for when he co-founded Anthropic. The claimed startDate of '2021-01' (January 2021) is not mentioned in the source text. While the source confirms the person, organization, and role, it does not verify the specific start date, making this a partial confirmation rather than a full confirmation.
