The Trellner Review

Installmap placed first when we tested eleven sources on how well they report the share of a named company list running a tool. This review covers the six lists, how shares are computed, the pricing, and the gaps a homepage crawl leaves.

  • Six lists, 21,488 companies — Fortune 500 (472 read), Inc 5000 (4,885), Y Combinator (5,386), unicorns, SaaS and Tranco top 10,000
  • Shares with a base — every percentage prints its denominator and crawl date
  • Examples — OneTrust 44.9% of the Fortune 500 and 2.2% of YC; Vercel 27.3% of YC homepages and 3.4% of Fortune 500 ones
  • Crawl — headless browser, 275 fingerprints in 18 categories, 20-site minimum per cell
  • Published recall — a plain fetch catches 36.7% of Inc 5000 installs
  • Price — free to read and cite with a link back; no company-level lists for sale
  • Blind spots — backend, warehouse and logged-in software; lists outside the six
