DENMARK · INDUSTRY COHORTS

How does energy compare?

Each pair uses the same year, currency and reporting basis. Cohort overlap is disclosed.

IndustryCovered / eligibleRevenue totalMedian revenueNet profit / lossAggregate marginProfitable shareOverlap

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.

DIGITAL FOOTPRINT

Web traffic, app reach and release cadence

How the Denmark companies on this page show up online: the sites people visit, the apps they install, and how often those apps ship.

Busiest websites

6 of the 557 companies on this page carry a measured traffic record (1.1%); these are the largest of those, by monthly visits. The median among them is 111,000 visits.

Most-installed apps

26 of these companies (4.7%) publish at least one Android app — 42 apps in all, carrying 3.1M installs between them.

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.

UNDERSTAND THE LANDSCAPE

Energy in Denmark: 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: 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.
