Percentiles computed over the modeled cohort (embedding + signal + tags). Sparse dimensions — network and press — reflect that most products have zero, so a single edge or mention lifts the rank; read those with the coverage flag.

Higher risk than 10% of the universe.

This is a model estimate, not a verdict. 78,505 of the 79,105 modeled products are unlabeled and scored by the model only.

  • LightGBM · binary mortality (dead vs surviving)
  • Held-out AUC 0.71 · CV AUC 0.79 ± 0.05 · Brier 0.21
  • Trained on 600 verified labels (150 dead / 450 surviving)
  • Leakage-guarded: excludes status, discontinued_year, profile_maturity
  • Top drivers: tag breadth, signal, vintage, liveness, business model

n=600 is thin → 95% CI on AUC ≈ ±0.10. Treat as a directional signal, not a calibrated probability.

Analyst read

generated from the metrics above · no external narrative

Windmill sits in the 53th percentile of Launch Sentinel's 79,105-product universe by signal, ranked #3,535 of 7,723 in Developer Tools. The mortality model puts its probability of going inactive at 4% — a model estimate with a wide confidence band. It sits on the competitive-alternatives graph with 2 linked rivals, so the comparable set below leans on curated edges. Signal momentum is roughly flat.

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. Signal & P(dead) are real / model.

Funding & team

not in source

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.
