Roche's nearest audiences are a dense mix of pharma peers, enterprise B2B brands, and tech-world executives — with no single neighbor pulling far ahead of the rest. Similarity here measures how closely two entities' audiences resemble each other in composition; across the top 10, scores run from 0.97 down to 0.93, a narrow band that defines the flat shape.
Six of the ten neighbors are Healthcare brands: Genentech (0.97), Johnson & Johnson (0.95), Merck (0.95), Pfizer Inc. (0.94), Novartis (0.94), and AstraZeneca (0.93). That core is expected — Roche is itself a Healthcare brand — but the remaining four slots go elsewhere. IBM (0.93) and Accenture (0.93) are B2B services firms; Satya Nadella (0.94) is classified as a Professional; and Marc Benioff (0.93) is a Tech Personality. The cross-kind presence of enterprise technology and executive figures alongside the pharma cluster is the defining structural feature of this top 10.
The flat shape, combined with that B2B and tech-executive presence, points to an audience that moves fluidly across institutional healthcare and the broader professional-technology world.
