About us

At deveritec, you’ll work on technologies that are truly technically challenging. We develop complex electronic systems at the intersection of hardware and software, and we deliberately focus on areas where there are no easy solutions. Our focus is on deep-tech projects: high-performance signal processing, modern wireless technologies, IoT systems (including Matter), energy-efficient power electronics, and specialized fields such as photonic computing and quantum electronics. We combine hardware development, embedded software, and FPGA design into comprehensive system solutions. With our in-house electronics manufacturing (EMS), we support projects from the initial concept through prototyping to series production. For you, this means: You see how your development is actually implemented, can directly contribute to the process, and benefit from a short feedback loop between design, testing, and production.
