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. 22 of 51 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

It measures the tracked company ecosystem, recorded funding, hiring and other available evidence. It is not a market-size estimate.
No. A company can belong to several segments, so segment counts and funding can overlap.
A dash or unavailable panel means the current reviewed source snapshot does not support that figure.
Company ecosystem snapshot: 2 September 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.
