Revenue, profitability & financial strength
Annual accounts for reporting companies linked to this landscape, on like-for-like currency and reporting bases.
Display conversions use the dated reference rates above. Where a verified rate is unavailable, figures retain their source currency. Each reporting cohort keeps its currency and accounting basis separate.

How does telecom compare?
Each pair uses the same year, currency and reporting basis. Cohort overlap is disclosed.
| Industry | Covered / eligible | Revenue total | Median revenue | Net profit / loss | Aggregate margin | Profitable share | Overlap |
|---|
Available-account cohorts are not estimates of whole industries. Overlapping entities can occur in more than one cohort; do not add cohort totals.
Coverage, calculations & financial sources
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.
Release cadence by quarter
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. 181 of 253 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

Clear definitions for making better comparisons.
What does this landscape measure?
It measures the tracked company ecosystem, recorded funding, hiring and other available evidence. It is not a market-size estimate.
Can segment counts be added together?
No. A company can belong to several segments, so segment counts and funding can overlap.
What does a missing figure mean?
A dash or unavailable panel means the current reviewed source snapshot does not support that figure.
Company ecosystem snapshot: 6 August 2026. Funding is recorded in USD; filed accounts retain their stated currency and reporting basis. Each section identifies its own coverage. The news and research behind these sections is explorable in Prism.
