An industry ecosystem,
measured in context.
24 featured companies from the funding, hiring, revenue and team-size leaderboards.
Locked revenue figures are available in Radar; the eight company financial previews stay the same throughout this page. A dash means the figure is outside these featured lists. Revenue years vary by company; the figures are not a like-for-like revenue comparison. Compare annual accounts ↗
Recently founded means a recorded 2023–2026 founding year and no recorded parent, acquirer or public-company status. These companies are not labelled startups without that separate classification.

Available-account cohorts are not estimates of whole industries. Overlapping entities can occur in more than one cohort; do not add cohort totals.
Filed annual accounts for exact designated national identifiers. Every aggregate and peer pair uses one fiscal year, source currency and reporting basis; periods, coverage and overlap are explicit; 2026 partials are excluded.
The same up to eight reporting entities remain open across years, filters and sorts. Other company figures are available in Radar.
Source currencies and accounting bases stay separate. Missing accounts are excluded rather than treated as zero. Exact reporting periods appear on company previews. Annual totals can change with coverage and do not measure growth of a fixed company cohort.

A company can carry several segment tags, so these rows overlap and should not be added together. Trend lines are zero-based and share one quarter grid, so a flat line is a quiet segment, not a missing one.
New apps published, beside apps whose most recent update landed in that quarter — the second bar is how much of the shelf is still being maintained.
Darker bars are new releases, lighter bars apps updated. 742 of 764 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

Institution and researcher rankings use citations to their covered work. Research scope: United States. This may be broader than the company geography.
Compare demand signals in the United States’s newsflow with the energy categories mapped to each signal.
Signal percentile − supply percentile = gap in percentile points. Positive gaps highlight questions to investigate. A high signal can reflect spending pressure or access friction, as well as potential demand.
The comparison is relative to the signal families on this page. A supply percentile of zero means the lowest relative reading, not zero companies. It is a prioritisation clue, not measured market size or unmet demand.
Signal and mapped-supply percentiles, their gap, and change in the signal’s article share.
