Lemberg Solutions vs Bluefruit Software: 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.
Bluefruit Software
Testing is the main reason buyers pick Bluefruit Software. The Redruth, Cornwall company has worked on embedded software since 2000, became employee-owned through an Employee Ownership Trust in 2019, and applies a Lean-Agile process with unit tests and test automation built in from the first sprint. It reports work on more than 100 products (per company website; independently unverifiable), with medical devices, scientific instruments and industrial equipment making up much of the portfolio. In 2023 it had about 75 staff and was hiring.

Lemberg Solutions vs Bluefruit Software: 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 |
| Bluefruit Software | |
|---|---|
| + | Test-first culture produces the unit-test and verification records auditors ask for in IEC 62304 work |
| + | Employee ownership tends to mean lower staff turnover on long projects |
| + | Comfortable taking over and stabilizing legacy C code written by someone else |
| + | UK base and working hours suit British and Western European clients |
| - | No electronics or PCB design, so hardware must already exist or come from elsewhere |
| - | UK rates are higher than Eastern European or Indian alternatives |
| - | Agile time-and-materials contracts may not suit buyers who want a fixed price |
