Founded in San Francisco in 2013, we have grown into the #1 producer of single-crystal diamond globally. We are the rare unicorn that has grown fast profitably. Ours is one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy. We are now in the 2nd stage of our 30-year master plan: 2013+: Deliver sustainably created diamond for wherever mined diamond has been able to go. Reform diamond jewelry in the process. 2023+: Put a diamond behind every high-power chip. Solve the thermal limitation at the foundation of todays most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to create the worlds first single-crystal diamond wafers — and created the world’s most compact power electronics with it: 8x smaller than Tesla’s. 2033+: Diamond semiconductors. Transistors with 17,300x the semiconductor merit over silicon. In 100 years, no-one will remember what Google was but all tech will be based on diamond electronics.
