NoteThe source is Anthropic's company values and governance page. While it mentions that Anthropic has 'policy experts' on its team and describes a 'Policy' function, it does not list individual personnel by name. The only named individuals in the source are the Board of Directors (Dario Amodei, Daniela Amodei, Yasmin Razavi, Jay Kreps, Reed Hastings, Chris Liddell) and LTBT Trustees. Jack Clark is not mentioned anywhere in this excerpt. The claim about Jack Clark's role, co-founder status, and start date cannot be verified or contradicted by this source material.
