NoteThe source is Anthropic's company page describing their mission, values, and governance structure. While it confirms Anthropic exists and lists current board members, it does not provide information about Sam McCandlish or his role as co-founder. The absence of his name from the board listing does not contradict the claim (he may have been a co-founder but no longer on the board), but the source simply does not address the specific personnel record being verified. This is unverifiable based on the provided source text.

NoteThe source directly confirms all three key fields: (1) person 'Sam McCandlish' is named as a co-founder in the founders list; (2) org 'Anthropic' is the company being discussed; (3) role 'Co-founder' is explicitly stated in the infobox and text; (4) startDate '2021-01' is confirmed as the company was founded in 2021 (the source does not specify the exact month, but January 2021 falls within the founding year). The record is accurate and supported by the source.
