Lux Capital
Lux Capital is a New York City-based venture capital firm founded in 2000 by Josh Wolfe, Peter Hebert, and Robert Paull that backs entrepreneurs building companies at the frontier of science and technology, turning "sci-fi into sci-fact." The firm systematically mines academia and government research labs for breakthrough technologies that have matured beyond proof-of-concept but have not yet attracted mainstream venture attention, then makes long-term bets on contrarians and outsiders challenging the status quo. Lux invests primarily at early stage across three focus areas: AI and technology, defense/space/ manufacturing, and biotech/healthcare, with an emphasis on deep tech, robotics, and emerging science. The firm manages roughly $7 billion in assets under management across nine core funds, closing Lux Ventures IX at $1.5 billion in January 2026, and has invested in over 200 companies. Through Lux Labs, launched in 2024, the firm has also helped create more than 20 new companies. Notable portfolio companies include Anduril, Applied Intuition, Databricks, Cognition, Ramp, Runway, Recursion Pharmaceuticals, Planet, and Saildrone. Lux is headquartered in New York City with an additional office in Silicon Valley.

Cohort brief
Auto-generatedThe 78 portfolio companies with APIs in the catalog, backed by Lux Capital, scored on the Kin Score. Every figure below is computed from the catalog — nothing here is written.
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Discoverability | 56.5 | 58.2 | -1.7 | 78 |
| Contract Governance | 3.9 | 6.3 | -2.4 | 78 |
| Operational Transparency | 9.2 | 13.6 | -4.4 | 78 |
| Contract Quality | 12.8 | 17.6 | -4.8 | 78 |
| Developer Ergonomics | 17.6 | 23.1 | -5.5 | 78 |
| Access Clarity | 20.9 | 26.4 | -5.5 | 78 |
A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 14% | 15% | -1 |
| MCP server (first-party) | 13% | 12% | +1 |

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.

Coverage caveat. 71 of 78 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 3 October 2026, across 28834 providers, using the same computation served by the APIs.io cohort API. Briefs are published for rosters of 5 or more scored providers; below that a distribution is not meaningful.
