American Express Business draws its nearest audiences from business media and journalism — not from other B2B brands. Across the top 10 neighbors, scores compress into a narrow band from 0.94 to 0.95, with no single entity pulling away from the rest.
The cluster is built almost entirely from two subcategories: news publishers and magazines. Fortune (0.95) and Inc. (0.95) lead the set, followed by Entrepreneur (0.95) — three business-oriented magazines whose audiences closely mirror this one. News publishers fill out the rest: The Wall Street Journal (0.95), HuffPost (0.95), CNBC (0.94), and Reuters (0.94). Two journalists — Arianna Huffington (0.95) and Christiane Amanpour (0.95) — sit inside this media cluster rather than outside it. The one structural outlier is Zappos.com (0.95), a footwear brand whose audience shape nonetheless lands squarely within this group. No other B2B brand appears in the top 10.
The flat shape and tight score range suggest an audience defined less by any single affinity than by a consistent orientation toward business news, professional media, and informed commentary.
