Anthropic — Founded By: sid_zR4nW8xB2f, sid_tKMznr07QA, sid_4CY8YJCrM7, sid_Tz48rTriBg, sid_x16GL4gP2A, sid_ENl8sgChDQ, sid_YqSmRNVRAg

NoteThe claim specifies seven founders with opaque identifiers (sid_xxxx format). The source confirms Dario Amodei and Daniela Amodei are associated with Anthropic (listed as Board members), but the source does not explicitly state who the founders are or provide a complete founding team roster. The source mentions 'The Team' section describing researchers, engineers, and leaders, but does not name Tom Brown, Chris Olah, Jared Kaplan, Sam McCandlish, or Jack Clark, nor does it provide the opaque identifiers. The additional context claims 'Seven former OpenAI researchers' founded Anthropic, which is plausible but not verified by this source. Since the source does not directly address the complete founder list or the opaque identifiers, this claim is unverifiable from the provided source text.

NoteThe source URL (https://anthropic.com/company) is the company's official 'About Us' or company page, which would be the appropriate place to find founder information. However, the provided excerpt from this page does not contain any list of founders or their names. The claim specifies seven named founders with ID codes, but the source text provided does not address this claim at all. While the source is relevant to the topic, it does not contain the specific data point being verified, making this unverifiable based on the given source material.
