Risk read derived from observed signals
The recorded URL now redirects offsite — often an acquisition, rebrand, or wind-down; the destination is recorded in the telemetry below. Pulse has been flat over the last 30 days.

Knowfox's listed URL redirected off its original domain (to https://nnh9i24929fkhwr.transferhafen.de/) when we last probed it on Aug 24, 2026 — we mark it redirected, not dead. Its Pulse Index is 16.0 of 100, built from 2 of 4 observed signal families. Observed footprint: 11 functional tags. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags.
Confidence reflects source and category coherence: curated = an editorially linked alternative; similar = strong functional tag-overlap in the same category; tag-overlap = shared tags only and may be noisy. Overlap is the shared functional-tag ratio (Jaccard) for tag-matched rows. Pulse is the observed-activity index real and 30d Δ its signed month change; a dash means insufficient observed history, never zero.

No disclosed funding in our sources. Funding data covers only ~1% of the corpus (462 rounds across 79K products), so absence here is unknown, not zero— we don't estimate a number we can't source.
