A new kind of mining company
Mariana Minerals is a software-first, vertically integrated minerals company focused on supplying critical minerals — including lithium, copper, and nickel — for modern energy, AI, and defense technologies. The company builds an integrated software platform spanning the entire mine lifecycle, from capital project delivery to operations and chemical refining, replacing fragmented workflows with real-time coordination, telemetry-driven control, and AI-optimized decision-making. Headquartered in Houston with offices in San Francisco, Mariana has three US sites under development and aims to bring 10 mineral projects into production in 10 years. Backed by Andreessen Horowitz, the company raised $85M in Series A funding.
