Fast Company's top 10 nearest neighbors span three subcategories — Magazines, News Publishers, and Websites — with no single neighbor pulling significantly ahead of the rest. Similarity scores here measure how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape.
The shape is flat: the top score, Ad Age at 0.99, sits only 0.007 above the tenth-ranked neighbor, Fast Co. Impact at 0.98. That compressed range means no structural anchor dominates — the audience looks equally at home across a wide band of professional media. Four of the ten neighbors are fellow Magazines: Ad Age (0.99), WIRED (0.98), Mashable (0.98), and Harvard Business Review (0.98). Three are News Publishers — Bloomberg Businessweek (0.98), The Economist (0.98), and ForbesWomen (0.98) — and three are Websites: Medium (0.98), eMarketer (0.98), and Fast Co. Impact (0.98). No Celebrities and Influencers appear in the top 10, and the mix cuts across business, technology, and general-interest professional publishing rather than clustering tightly within any one editorial lane.
The flat, high-scoring cluster signals an audience whose shape is broadly shared across the professional media ecosystem — one that doesn't belong distinctively to any single outlet type.
