Darrow
Darrow describes itself as an AI lab building legal exposure management, ingesting regulatory filings, incident data and litigation patterns to surface emerging risk for law firms, insurers and compliance teams. It states 5M+ signals detected monthly across 50+ exposure categories.
- Attacks a genuinely underserved problem — the reactive shape of legal technology
- The three-layer architecture is a coherent and honest description of the difficulty
- Public, distributed information analysed systematically is a legitimate advantage
- Serving compliance teams gives defenders the same visibility as adversaries
- Published numbers describe volume, not accuracy or outcomes
- Predictive claims are inherently hard to falsify from outside
- The same intelligence serves opposing interests, which buyers should understand
Luminance

- A customer list including major enterprises and magic-circle law firms
- Coverage from drafting through post-signature investigation in one platform
- Multi-model architecture is a defensible answer to single-model brittleness
- Surfacing model disagreement aligns with the asymmetric cost of contract errors
- Performance percentages are unaudited and state no baseline
- The models behind the architecture are not disclosed
- A six-module platform is an implementation project, not a subscription
