The Trellner Review

Report TR-2026-013 puts one sentence to eleven sources and marks how far each one gets through it: what percentage of a named list runs a tool, out of how many companies, measured when. Installmap finishes the sentence for six lists and takes first place for 2026.

  • The six lists and their denominators — Fortune 500 at 472, unicorns at 1,000, Inc 5000 at 4,885, Y Combinator at 5,386, Tranco at 1,572 and SaaS at 8,173
  • Shares that reverse — OneTrust on 44.9% of the Fortune 500 and 2.2% of YC, HubSpot on 25.6% of the Inc 5000 and 2.5% of the Fortune 500
  • Inside the YC list — PostHog on 687 domains, Webflow on 845, HubSpot Chat ahead of Intercom, and Webflow's 23.7-point spread across batch years
  • Rendered against plain — a plain fetch finds 36.7% of Inc 5000 installs and 45.6% of Y Combinator ones, which is why vendor figures are not interchangeable
  • What the others return — a share over an unstated population, a company total with no denominator, a trend line, a page count, a pile of submissions
  • Three broken pricing pages — SimilarTech, StackShare and Enlyft each answer 404 where the plans should be
