sevenlab engineering GmbH

sevenlab is a senior embedded systems engineering team specialized in connected devices. Spun out of grandcentrix — Germany’s former IoT leader — we bring decades of experience from successfully delivered IoT projects for DACHs leading companies. We work with clients from concept to shipping device: from early ideation and concepts to system architecture, embedded software, electronics/hardware, manufacturing support, and lifecycle management. Our focus is on robust, secure, and maintainable systems — with particular interest in: 🔋 Ultra-low-power wireless devices — highly integrated hardware/software co-design with LPWAN, BLE, Wi-Fi 6E, Thread, and NFC ⚙️ Zephyr RTOS & Embedded Linux — application dev, platform porting, secure boot, OTA, protocol integration 📡 Cellular IoT & LPWAN — LTE-M, NB-IoT, LoRaWAN, Mioty, LwM2M, CoAP, MQTT-SN 🏙️ Smart Building & Industry — from Thread/Matter and DALI to KNX RF, IO-Link, Modbus, and beyond We bring an edge beyond the average dev shop: reverse engineering skills, DSP know-how, a joy in troubleshooting and a scientific mindset for solving hard problems. Working with emerging tech is our standard, not the exception. We are deeply rooted in open source culture. Our development philosophy is shaped by collaboration, learning from others', and continuously improving through open and critical peer reviews. There’s little we enjoy more than a thoughtful code review that challenges our thinking and assumptions. While we specialize in embedded systems, our network adds expertise in cellular connectivity, cloud/backend, apps, UI, industrial and antenna design — enabling us to deliver complete, production-ready solutions.
