Lemberg Solutions vs Bresslergroup (Delve): overview

Lemberg Solutions

Lemberg Solutions is an engineering firm founded in 2007 and headquartered in Lviv, Ukraine, with additional offices in Hamburg, Germany, London, United Kingdom, and Kraków, Poland. The 200+ person team builds RTOS and bare-metal firmware on FreeRTOS, Zephyr, and Azure RTOS, alongside secure boot, OTA update pipelines, and MISRA-aware testing for regulated clients. It holds direct partnerships with NXP, STMicroelectronics, and Microchip as primary semiconductor partners, plus an in-house lab with oscilloscopes and hardware-in-the-loop testing for board bring-up. Public case studies include a KONVOI truck security firmware audit and a Caltech medical device port to STM32, and the company holds ISO 9001, ISO 27001, and ISO 13485 certifications with full IP transfer to the client on delivery.

Bresslergroup (Delve)

Bresslergroup was founded in 1970 in Philadelphia, Pennsylvania, and reports roughly 83 employees. In 2021 the firm merged with the Midwest design consultancy Delve under Trinity Hunt Partners' ownership, and by June 2022 the combined company adopted the single Delve brand name, so new engagements are contracted under that name even though the Bresslergroup engineering history and team carried over. Its practice covers new product definition and development, including industrial design, mechanical and electrical engineering, and embedded software, for categories spanning consumer IoT products to medical devices.

Lemberg Solutions vs Bresslergroup (Delve): pros and cons

Lemberg Solutions
+ Direct partnerships with NXP, STMicroelectronics, and Microchip back up semiconductor-level claims instead of a generic all-chips pitch
+ In-house lab with oscilloscopes, evaluation kits, and HIL testing capability covers board bring-up work most pure-firmware vendors outsource
+ ISO 27001, ISO 9001, and ISO 13485 certifications plus MISRA-aware testing suit regulated industrial and medical firmware
+ Full intellectual property and source code rights transfer to the client on every engagement
+ Named case studies span automotive security auditing, medical device porting, and industrial telemetry rather than one vertical
- Does not manufacture finished devices or handle mass production in-house
- Does not obtain product regulatory certification on the client's behalf; the client or a third party owns that process
- Minimum engagement size is not published, so budget fit requires a direct conversation
Bresslergroup (Delve)
+ More than five decades of product-design and engineering history dating back to 1970
+ 2021 merger with Delve added complementary design and engineering resources rather than a competitor absorbing a smaller rival
+ Covers industrial design, mechanical/electrical engineering, and embedded software in one engagement
- The 2021 to 2022 rebrand to Delve means new client contracts and public materials now use a different company name than the one with the longer track record
- Firmware is one part of a broader industrial design and product development practice
