Terranox AI

Terranox AI is the first vertically integrated, AI-powered uranium discovery company, founded in 2026 and part of Y Combinator's Winter 2026 batch. The company finds high-grade uranium deposits in North America by training machine learning models on more than seventy years of exploration outcomes locked in thousands of legacy PDFs, drill logs, and hand-drawn geological maps. Traditional uranium exploration has a hit rate below one percent and timelines measured in decades; Terranox aims to raise that hit rate and compress discovery time to help supply the fuel a global nuclear-energy resurgence needs — the world must roughly quadruple uranium production by 2050. Terranox is a private operating company focused on geoscience and mineral exploration and does not currently publish a public developer API, SDK, or developer portal. It is backed by General Catalyst, 776 Ventures, and Y Combinator.

Terranox AI is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Machine-Learning, Energy, and Nuclear.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
