IoT Development Company in Poland
Custom IoT hardware, embedded firmware, cloud and mobile development — from PCB design to production.
FSS Technology is a Polish IoT development company based in Bielsko-Biała, Poland. It designs custom electronics and PCBs, develops embedded firmware, connects devices to cloud infrastructure, builds mobile applications and assembles PCBs in-house.
From concept to production, under one roof.
Most IoT projects stall at the hand-offs: the hardware vendor, the firmware contractor, the cloud agency and the assembly house. At FSS every layer is designed and built by the same team.
