Annual accounts availability

The measured Germany identity-to-filing probe did not produce a qualifying designated legal or national-ID join: designated German registry identities do not carry the LEI or ISIN used by bundesanzeiger facts; legal-name matching is prohibited.

DIGITAL FOOTPRINT

Web traffic, app reach and release cadence

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

Busiest websites

18 of the 1,928 companies on this page carry a measured traffic record (0.9%); these are the largest of those, by monthly visits. The median among them is 259,155 visits.

241 of these companies (12.5%) publish at least one Android app — 385 apps in all, carrying 31.7M installs between them.

Installs are lifetime totals to date at the June 2026 store reading — a measure of reach, not of people using an app today.

App reach by segment

The busiest app inside each of this page’s own segments, with the quarterly release trend behind it (2024Q1–2026Q2).

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.

HOW TO READ THE GAP

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.

UNDERSTAND THE LANDSCAPE

Energy Tech in Germany: 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.
