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.

Backed by Andreessen Horowitz, the company raised $85M in Series A funding.
