Atomic Machines is doing something truly epic: inventing the future of how things are made. And a glorious future it will be. We envision an era of atomically precise manufacturing (APM), in which everything is made by assembling matter at the molecular level, making anything from its digital description, blurring the line between bits and atoms. Our first move on the long journey to this APM future is in the realm of microfabrication, making mechanical devices with features sized in the single-digit microns scale. Our fabrication technology will be full-stack, 100% automated and data-driven, and we’re expanding the engineering team now to take it to commercial reality. We have engineering offices in Berkeley and Santa Clara, CA. We are well funded, and our leadership has a long track record of success. We have successfully developed multiple prototype generations of our first MEMS device and are benefitting directly from the direct-write nature of our fabrication technology, going from bits to atoms in hours, not months or years.
