We design, manufacture and sell precision replacement parts and IoT products — from our workshop in Stockholm, Sweden.
BraDev is a Swedish product development company based in Stockholm. We specialize in identifying weak points in everyday products and engineering permanent solutions — using modern manufacturing techniques like metal 3D printing (DMLS) and custom electronics.
When car manufacturers cut corners with plastic gears that are doomed to fail, we replace them with stainless steel. When a home automation problem needs solving, we build the hardware and software to fix it.
Every product we sell is designed in-house, manufactured to tight tolerances, and backed by hundreds of satisfied customers worldwide.
