Lemberg Solutions vs Sigma Software: overview

Lemberg Solutions

Few IoT vendors can design the circuit board, write the RTOS firmware, program an FPGA and build the cloud back end without subcontracting part of it. Lemberg Solutions does all of that with 200+ engineers, working since 2007 from Lviv and Kraków with client-facing offices in London and Hamburg. Its connectivity and edge AI work is backed by partnerships with NXP, Microchip and STMicroelectronics, plus an in-house lab for prototyping and testing. Clients include Bosch Rexroth, Astronics, Caltech, Cellink, Ferno and Speede.

Sigma Software

Sigma Software was founded in 2002 and is part of the Swedish Sigma group. It describes a team of over 2,100 professionals in offices across 19 countries. Embedded and automotive software are among its practices, alongside a wide range of web, cloud and enterprise work. IoT buyers will find capable firmware and cloud engineers, but not a hardware design house.

Lemberg Solutions vs Sigma Software: pros and cons

Lemberg Solutions
+ Designs the electronics as well as the software, so firmware problems caused by a board revision get fixed by the same team
+ Partnerships with NXP, Microchip and STMicroelectronics help with early silicon access and vendor support
+ In-house lab shortens the loop between a prototype failing a test and a fix being tried
+ Builds products to the relevant industry standards and protocols, with ISO 27001 and ISO 9001 certification behind its security and quality processes
+ Edge AI and computer vision experience for devices that need to decide locally instead of sending everything to the cloud
+ Client owns all intellectual property, including hardware designs
- No in-house mass production; finished devices need a separate contract manufacturer
- Regulatory approvals such as CE, FCC or medical clearances stay the client's job, though Lemberg prepares the technical files
- A 200-person company can run several product teams in parallel but not a 100-engineer programme
Sigma Software
+ Swedish parent adds governance
+ Broad coverage of firmware, cloud and apps
+ Competitive rates
- IoT is not its main focus
- No electronics design
