The source text explicitly lists Sam McCandlish as one of the founders of Anthropic and confirms the company was founded in 2021. The record claims he is a co-founder at Anthropic with a start date of 2021-01 (January 2021). The source confirms both the person, organization, role (co-founder), and founding year. While the source does not specify the exact month (January), the year 2021 is confirmed, and the month-level precision in the claim is reasonable given the company's founding in 2021.
