Personnel: Sam McCandlish at Anthropic (Co-founder)

Note: The 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.
