Thomas McGrath @ Goodfire

NoteWhile the source confirms that Goodfire exists and is a research company focused on AI interpretability, it does not mention Thomas McGrath by name or specify his role as Co-Founder & Chief Scientist. The source discusses the team in general terms ('founding members', 'researchers, engineers and builders') but provides no specific personnel details that would allow verification of the individual claim. The start date of 2023 is also not addressed in the source text. Without explicit mention of Thomas McGrath in the source, the claim cannot be confirmed or contradicted—it is unverifiable based on this excerpt.
