Durin was founded under the belief that raw materials should not be a constraint on civilization's progress. We are actively developing the technologies to make this possible, with the ultimate goal of becoming the foundation of the global supply chain. Our modern way of life, from smartphones to skyscrapers, starts as ore in the ground. But mines don't simply appear. In...

Our bet with Meter is simple: we’ll all use the internet more than we do today. That future depends on networking infrastructure—the invisible plumbing powering every application, space, and data center. But today’s infrastructure is dated and inconsistent, so we’re rebuilding it from the ground up. We design the hardware, write the firmware, build the software, deploy the networks, and run support. It’s...

Skip's mission is to energize cities by making mobility accessible to everyone. We believe this requires designing every aspect of a micromobility network from the ground up. This includes custom vehicle hardware, the software-defined fleet management system and ground operations for safety and recharging. Our success will make it easier for everyone to work, play and connect in their communities.

Atomic Semi is building a small, fast semiconductor fab. We’ll build the tools ourselves then quickly push them to more advanced geometries. We’re building a small team of exceptional, hands-on engineers to make this happen.

Observable Space is unlocking continuous, real-time observations of space with the industry’s first line of vertically integrated hardware and software products.
