NoteThe source is about Anthropic and matches the claim's subject. However, the source does not address the specific claim about founders. The source lists current Board of Directors (which includes Dario and Daniela Amodei) but does not provide a 'Founded By' list or mention Tom Brown, Chris Olah, Jared Kaplan, Sam McCandlish, or Jack Clark. The source also does not confirm the additional context that these were 'seven former OpenAI researchers.' While the claim may be factually accurate based on other sources, this particular source excerpt does not confirm or contradict it — it simply does not address the founding team composition.

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.
