IBM's top 10 nearest neighbors span four distinct subcategories — B2B brands, Healthcare brands, Tech Personalities, and business media — with no single neighbor pulling far ahead of the rest. Similarity scores run from 0.97 (Pfizer Inc.) down to 0.95 (Marc Benioff and AstraZeneca), a range of just 0.02 across the full set. That compressed band is the defining structural feature here.
The top 10 breaks down as follows: four B2B brands — Accenture (0.96), Deloitte US (0.96), Deloitte (0.96), and IBM's own sub-account IBM Data and AI (0.95) — sit alongside two Healthcare brands in Pfizer (0.97) and AstraZeneca (0.95), one News Publisher in Forbes Tech (0.96), one Airlines brand in United Airlines (0.96), one Magazine in Harvard Business Review (0.95), and one Tech Personality in Marc Benioff (0.95). The B2B subcategory — IBM's own — accounts for four of the ten neighbors, making it the plurality, but Healthcare and media channels together account for the other six. That cross-kind spread is notable: the audience shape IBM shares most closely is not confined to enterprise software peers but extends equally into pharma, consulting, business journalism, and a major airline.
The flat shape across this neighbor set points to an audience defined less by any single industry vertical than by a professional, enterprise-oriented orientation that cuts across sectors.
