Lemberg Solutions vs Plexus: overview
Lemberg Solutions
Founded in 2007, Lemberg Solutions builds both hardware and software, and has offices in Lviv, Hamburg, London and Kraków. For medical device teams it covers electrical engineering, firmware, RTOS and embedded Linux development, FPGA programming, GUI work, connectivity and IoT, edge AI and cybersecurity, so one vendor can own the device electronics, its embedded code and the cloud or mobile side that talks to it. Healthcare is one of its core industries alongside automotive, energy and logistics, and named clients include Astronics, Caltech, Ferno, Cellink and Bosch Rexroth. The company holds ISO 27001 and ISO 9001 certification and runs its own hardware lab. It does not manufacture finished devices at volume and does not obtain regulatory clearance on a client's behalf; it supplies the engineering documentation the client's regulatory team needs.
Plexus
Plexus Corp. is a NASDAQ-listed company headquartered in Neenah, Wisconsin, that offers design and development, supply chain, new product introduction, manufacturing and sustaining services. Healthcare and life sciences is one of its three markets alongside aerospace and defense and industrial. Its healthcare work includes surgical equipment, imaging equipment and diagnostic instruments. The company has around 20,000 employees in total, though only part of that is healthcare.

Lemberg Solutions vs Plexus: pros and cons
| Lemberg Solutions | |
|---|---|
| + | A single team covers electronics, firmware, cloud, data and AI, which cuts the hand-offs that usually slow connected-device programs |
| + | Partnerships with NXP, Microchip and STMicroelectronics give early access to silicon support and reference designs |
| + | ISO 27001 and ISO 9001 certified, with security designed into the product rather than bolted on before release |
| + | In-house electronics lab shortens prototype loops and lowers R&D risk before a design freeze |
| + | All intellectual property transfers to the client, and the cooperation model can be consulting, team extension or full product development |
| + | Practical edge AI and computer vision experience for devices that need on-board inference |
| - | No in-house mass production, so a separate contract manufacturer is needed once the design is ready to scale |
| - | Does not obtain FDA or CE certification for clients; it provides technical documentation and engineering support for the client's own submission |
| - | Not ISO 13485 certified per the information reviewed, so buyers should confirm how it works inside their own medical QMS |
| Plexus | |
|---|---|
| + | Strong with complex, lower-volume capital equipment such as imaging and surgical systems |
| + | Offers product engineering as well as manufacturing |
| + | Sustaining engineering over long product lives |
| + | Public company with transparent financial reporting |
| - | Generalist manufacturer; healthcare competes with aerospace and industrial for capacity |
| - | Not a fit for early-stage concept work |
| - | Most engineering engagements lead toward a manufacturing contract |
