How the atlas is researched

Every profile starts from the company's own pages and filings, then reputable reporting. Nothing is estimated: a figure without a source is left out.

  • 301sources cited across the profiles
  • 48chief executives confirmed against a 2025 or 2026 source
  • 7leader photographs with a free licence or from a press kit

Sources

  • Primary first: the company's website, press releases, filings and pricing pages.
  • Then reputable reporting: TechCrunch, Reuters, Bloomberg, the Financial Times, Digiday, Axios and trade press.
  • Data providers such as Crunchbase only as a last resort, and labelled as such.
  • Every figure carries its date, and every profile lists its sources.

Leadership and ownership

Leadership and ownership are checked against a 2025 or 2026 source. Where no current chief executive is named publicly, the profile says so rather than guessing. Each record is checked again every 90 days.

Images

  • Company logos and cover images are the companies' own, shown to identify them.
  • Leader photographs appear only with a free licence or from the company's own press kit, and carry their credit.
  • Section photographs are from Unsplash, credited to their photographers.

Independence

Inclusion is editorial. No company paid to appear, and appearing is not an endorsement. Order within a layer is alphabetical.

Corrections

Something out of date? Every profile has a correction form. Corrections are checked against a source before a record changes.

The seven layers

Each platform sits in the one layer that describes its main business. Many do more than one thing; the layer is where most of their revenue or attention comes from.

Leadership checked between 14 Nov 2026 and 14 Nov 2026. Each record is checked again every 90 days.
