sevenlab
sevenlab is a boutique German engineering service specializing in connected embedded systems and next-generation connectivity solutions. Their engineering focus centers on the intersection of networked devices, Zephyr RTOS, and Embedded Linux.
About
sevenlab support clients from concept to finished product, covering prototyping, electronics/hardware co-design, and systems engineering. They guide German Mittelstand OEM clients through the entire product lifecycle, from initial ideation and technology evaluation to system architecture design, development, manufacturing to product lifecycle management.
Their roots lie in grandcentrix, formerly Germany’s leading provider of IoT solutions and a subsidiary of Vodafone. Spun off in 2024 with a well-established team, they bring decades of practical experience delivering challenging consumer and industrial IoT projects.
Key products
sevenlab specialize in robust, maintainable, and secure solutions for connected embedded systems. Their key products and services include:
Native cellular design & connectivity sovereignty
hey design and develop connected devices from the ground up. Their development approach prioritizes technical independence, ensuring clients retain ownership of their connectivity stack, starting at module selection, regulatory matters, software licenses to modern Remote SIM Provisioning (RSP) standards like SGP.22 and SGP.32 across LTE, 5G, and NTN.
Global deployment & network triage
They have practical experience deploying devices into cellular networks worldwide and resolving real-world connectivity issues. They routinely collaborate directly with network providers, modem manufacturers, and infrastructure OEMs to analyze signaling and network logs, evaluate field performance, and translate those findings into stable device firmware.
Zephyr RTOS & embedded Linux ecosystems
Application and system development, platform/architecture porting, protocol/subsystem integration, driver development, verified boot, and secure device updates. As Zephyr and Linux Foundation Members and regular contributors, their development philosophy is rooted in open-source collaboration and rigorous peer review.
Ultra-low-power & smart applications
Integrated software/hardware co-designs for battery-powered devices (NB-IoT, Cat-M, Mioty, BLE, Wi-Fi 6e, Thread, UWB) and engineering for smart environments (Matter, 6LoWPAN, wM-BUS, KNX RF, DALI, Modbus, IO-Link, etc.).
Beyond standard product development, they bring a unique edge in reverse engineering, digital signal processing, and tackling R&D tasks using first principles. They are highly comfortable working with novel, unproven technologies.
Why sevenlab
sevenlab’s team is fluent in cellular technology and understands the motivations and realities faced by its Mittelstand customers. Their team is precise in its use of terminology, enabling it to clearly distinguish between terms like eSIM, eIM, SGP.32, SM-DP+, APDU, eUICC, Diameter, eNodeB, gNodeB, etc.
Whether analyzing complex network logs, staring at spectrum analyzers in the field, or running an in-house private cellular network (safely isolated in a galvanic box), they thrive in the physical realities.
