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: 3 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.
