Nozoïd is a synthesizer manufacturer founded in 2017 by Cyrille Henry, an electronics engineer based in the south of France. Before launching the brand, Henry worked as an electronics engineer at La Kitchen in Paris, building custom hardware for dancers, theater productions, and musicians, and later operated as an independent developer focused on real-time audio and visual tools. The OCS-2, his first synthesizer, was originally designed for personal use before being released commercially under the Nozoïd name.

The brand's tagline, "noise and sinusoids," reflects an emphasis on hands-on digital sound synthesis with dense knob-per-function panels. Its product line includes the OCS-2, a semi-modular digital synthesizer; the MMO-3, a monophonic synthesizer; the Nozori series of Eurorack modules (also available in software form for VCV Rack); and the Kagouyar, a digital polyphonic synthesizer built around cross-modulation between oscillators.

Nozoïd occupies a niche aimed at experimental and modular-leaning musicians who prefer immediate tactile control over menu-driven workflows, and the products are typically sold direct through the company's own shop.

Nozoid has 2 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include Jean Michel Jarre.
