Notion's top 10 neighbors are a tight, mixed cluster of Technology brands, developer-focused websites, and tech-adjacent personalities — with no single neighbor pulling far ahead of the rest.

The shape is flat: scores run from Slack at 0.96 down to Vitalik Buterin at 0.94, a band of just 0.02 across all ten positions. Four of the ten neighbors share Notion's own subcategory — Technology brands: Slack (0.96), Figma (0.96), GitHub (0.95), and Stripe (0.95). The remaining six cross into other kinds entirely: The Verge (0.95) and Codecademy (0.94) are websites, DEV Community (0.94) is a developer-focused website, and then — notably — two celebrities appear: Hasan Minhaj (0.94), a comedian, and Kal Penn (0.94), an actor, alongside Vitalik Buterin (0.94), a tech personality. The presence of a comedian and an actor inside a cluster otherwise dominated by productivity software and developer tools is the most structurally unusual feature of this top 10.

The overall picture is an audience shaped primarily by the tech-builder world — developer platforms, startup infrastructure, and tech media — but one whose composition is broad enough to pull in figures well outside that core.
