Headspace's top 10 neighbors span journalists, activists, authors, podcasts, and education — with no other Technology brand appearing in the set, and no single neighbor pulling significantly ahead of the rest.

Similarity here measures how closely two entities' audiences resemble each other in composition. The shape is flat: the scores run from Tim Ferriss at 0.95 down to Nate Silver and The Points Guy at 0.95, a band of less than 0.005 across all ten. No neighbor dominates; none falls away. The top 10 break down across five subcategories: Authors (Tim Ferriss), Education (TED Talks), Activism (Everytown, March For Our Lives), Activists (Monica Lewinsky), Podcasts and Radio (NPR's Planet Money), Magazines (Scientific American), Comedians (John Oliver), and Websites (The Points Guy). The dominant grain is civic and intellectual: journalism-adjacent podcasts, science publishing, activist organizations, and public-interest media. Headspace's own subcategory — Technology — has no representative in the top 10.

The flat, cross-kind shape suggests an audience defined less by what Headspace is than by a consistent civic-intellectual orientation that cuts across media formats and causes.
