About Niobium Microsystems
Niobium Microsystems builds hardware to accelerate fully homomorphic encryption, a method that lets software compute on data without ever decrypting it. The workload is very slow on ordinary processors, so Niobium is developing a system-on-chip, offered as a PCIe card for existing servers, along with a compiler and software kit. It has also described an encrypted cloud platform for private AI using FPGAs, which are reprogrammable chips. The company is headquartered in Dayton, Ohio, and was spun out of the research firm Galois in 2021.
Niobium Microsystems was founded in 2021 and is based in Dayton, OH, United States. It is listed under ASICs. Reported funding is $23M+ follow-on round (Dec 2025).

What Niobium Microsystems works on
ASICs
An ASIC, or application-specific integrated circuit, is a chip designed to do one job or a narrow set of jobs. Its circuits are fixed when the chip is made. A CPU can run any program; an ASIC does what it was designed for and nothing else.
