About Still Bright

Still Bright is a seed-stage, deep-technology startup dedicated to solving the world's critical copper shortfall. The transition to a secure and sustainable economy depends on a massive expansion of copper supply, yet traditional extraction methods face significant environmental and permitting challenges.

Our proprietary hydrometallurgical process is designed to improve copper yields at currently producing mines as well as unlock vast, untapped copper and other co-located metal resources. As a closed-loop system, our technology offers precise control over all outputs, minimizing environmental impact and maximizing value.

Backed by top-tier investors, including Breakthrough Energy Ventures and Material Impact, our team is designing and executing its pilot and is preparing the next stages of commercial deployment.

We prioritize the well-being of our employees, customers, and communities, and work to create a positive impact on the world through our business practices. We especially encourage applicants from historically marginalized communities to join our mission of sustainable metals extraction.
