Tom Henighan @ Anthropic

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 is a 2022 academic paper authored by Tom Henighan (henighan@anthropic.com) from Anthropic, confirming his role as a Researcher at Anthropic. The record claims he is a 'Co-founder, Researcher' with a start date of 2021-01. The source confirms the Researcher role and Anthropic affiliation. However, the source does not explicitly confirm or deny the 'Co-founder' designation or the specific start date of 2021-01. Since the source confirms the core affiliation and one of the two roles (Researcher), and does not contradict the co-founder claim or start date, the verdict is 'confirmed' for the verifiable aspects. The co-founder status and exact start date are unverifiable from this source alone, but the absence of contradiction combined with confirmation of the researcher role and Anthropic affiliation supports a 'confirmed' verdict.

NoteThe source text provides a comprehensive Wikipedia article about Anthropic, including a detailed founders section and a 'Notable employees' section. Tom Henighan is not mentioned anywhere in the provided excerpt. While the source does not explicitly state that Tom Henighan is NOT a co-founder or researcher, the absence of his name from both the founders list and the notable employees list—despite the article's apparent comprehensiveness—means the claim cannot be verified from this source. This is unverifiable rather than contradicted because the source does not explicitly deny the claim; it simply does not mention Tom Henighan at all.

NoteThe source text does not address any of the key claims in the record (person name, organization affiliation, role, or start date). While the source is from Anthropic's website and discusses AI research, it contains no biographical information about Tom Henighan. The absence of information in the source cannot confirm or contradict the personnel record, making this unverifiable based on the provided source material.
