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. 29 of 76 apps carry a release date. The series ends at 2026Q1, the last quarter that closed before the June 2026 reading.

UNDERSTAND THE LANDSCAPE

Energy in Sweden: key questions

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: 31 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.
