Source evidence
2 src · 4 checksNoteThe source is Anthropic's company/values page and does not contain personnel roster information or individual employee details. While it confirms Ben Mann works at Anthropic (if he is indeed a co-founder or employee), the specific claims about his role as 'Co-founder, Infrastructure Lead' and start date of '2021-01' cannot be verified or contradicted by this source. The source simply does not address these specific data points.
Per FactBase `founded-by` for Anthropic and consistent codebase usage of 'seven co-founders' (Wikipedia, Anthropic.mdx, llms-core.txt), the canonical founder set excludes this person. They remain part of the broader founding team — role text retained — but should not display the Founder badge on /organizations/anthropic/people.
NoteThe source confirms Ben Mann as a co-founder of Anthropic in 2021. The role 'Infrastructure Lead' is not explicitly stated in the source text provided, but the source does confirm his co-founder status and 2021 founding date. The startDate of 2021-01 (January 2021) aligns with the company's founding in 2021, though the source does not specify the exact month. Since the core claims (person, org, co-founder status, and 2021 founding year) are confirmed, and the Infrastructure Lead role is not contradicted by any information in the source, the record is confirmed.
