Lemberg Solutions vs Integra Sources: overview
Lemberg Solutions
Lemberg Solutions takes a device from schematic to field updates under one roof: electrical engineering, bare-metal and RTOS firmware, embedded Linux, FPGA programming, GUI work, connectivity and edge AI. The company started in Lviv in 2007, now has more than 200 people, and also runs offices in Hamburg, London and Kraków. Its firmware practice works across STM32, NXP i.MX and LPC, Microchip PIC and SAM, Nordic and Espressif parts, with FreeRTOS, Zephyr, Azure RTOS and VxWorks listed in its stack, and it holds partner status with NXP, Microchip and STMicroelectronics. Named clients include Astronics, Caltech, Speede, Ferno, Cellink and Bosch Rexroth. Processes are certified to ISO 27001 and ISO 9001, and an in-house lab with oscilloscopes, spectrum analyzers and evaluation kits is used to validate firmware on real hardware before it ships.
Integra Sources
Two hardware and software engineers set up Integra Sources in 2014, and it now operates from Astana, Kazakhstan with a team in the low dozens. Its service list covers electronics design, embedded firmware, Linux kernel and driver development, computer vision and robotics, and it has collected a long run of Clutch reviews for IoT and device projects. Rates are below those of the European and US firms on this list. Buyers get engineers comfortable at the register level, though with less of the process documentation that regulated industries expect.

Lemberg Solutions vs Integra Sources: pros and cons
| Lemberg Solutions | |
|---|---|
| + | One team covers schematics, PCB layout, MCU firmware, cloud back end and the companion app, so integration problems surface inside a single project plan |
| + | ISO 27001 and ISO 9001 certified, with secure boot, image signing and OTA rollback offered as standard firmware work items |
| + | Partner status with NXP, Microchip and STMicroelectronics gives earlier access to silicon support and reference designs |
| + | Edge AI experience runs from sensor integration and DSP to on-device inference and computer vision |
| + | In-house lab lets the team validate firmware against real boards and RF conditions before the client receives a build |
| + | All intellectual property rights transfer to the client, across consulting, team-extension and full-product engagements |
| - | Mass production is not handled in-house; the team supports a product through development and maintenance but does not manufacture finished devices |
| - | Regulatory certification is not obtained on the client's behalf; Lemberg supplies the technical documentation and engineering support for approvals |
| - | Broad scope means a buyer who only needs a single low-level driver may be paying for capabilities they will not use |
| Integra Sources | |
|---|---|
| + | Kernel module and device driver work is a stated speciality |
| + | Rates make it one of the more affordable options for low-level engineering |
| + | Can take a product from schematic through firmware for small hardware startups |
| - | Small team with limited capacity for parallel projects |
| - | Little public evidence of IEC 62304, ISO 26262 or similar regulated development |
| - | Time-zone gap with North American clients |
