Tumi's top 10 nearest neighbors span casual dining, general apparel, grocery retail, electronics, and tech personalities — with no single category dominating and scores compressed into a narrow band from 0.91 to 0.94. Similarity here measures how closely two entities' audiences resemble each other in composition; the tight range signals a flat shape with no standout anchor.

The leading neighbor is California Pizza Kitchen at 0.95, followed closely by Nordstrom at 0.94, Trader Joe's at 0.93, and The Cheesecake Factory at 0.93. Apple Retail Store sits at 0.93 as well. Three of the top 10 are apparel brands — Nordstrom, Banana Republic, and Nordstrom Rack — but they share the space with casual dining, grocery, and electronics, none of which are Tumi's own subcategory (Jewelry and Accessories). Coach is the only other Jewelry and Accessories brand in the top 10, arriving at position 37 in the broader set at 0.89.

The tech personality cluster — Chamath Palihapitiya at 0.92, Naval Ravikant at 0.91, and Cathie Wood at 0.91 — adds a distinctly professional, business-oriented dimension to the mix, sitting alongside The Shade Store at 0.91 and MIT Technology Review at 0.91.

The flat shape across this cross-category cluster points to an audience defined less by any single vertical than by a consistent lifestyle and professional profile that cuts across dining, retail, media, and tech.
