About Cenfire

Cenfire is a Santa Barbara-based startup dedicated to revolutionizing the switching and power industries. Its groundbreaking switching technology was developed over several decades at Atomica, the largest MEMS foundry in the U.S. Cenfire’s switch is exclusively manufactured at Atomica’s California facilities.

Cenfire’s core technology was developed in response to that pattern. Instead of building a custom switch for a narrow niche, the architecture was designed as a silicon based, galvanically isolated MEMS switching platform using proven material sets and semiconductor compatible processes, with robustness and yield engineered in from day one.

Cenfire began inside Atomica, one of the few U.S. foundries capable of manufacturing complex MEMS devices.

Over the years, multiple venture backed MEMS switch companies developed products there, each promising breakthrough performance. Technically, many succeeded in demonstrating compelling devices. Commercially, many did not survive. The pattern was consistent: architectures optimized for peak performance but not for yield stability, packaging robustness, or scalable manufacturing economics.

The insight was clear. MEMS switching did not fail because the physics was flawed. It failed because it was not engineered as a manufacturable, scalable platform from the beginning.
