Lemberg Solutions vs Zone7 Engineering: overview

Lemberg Solutions

Lemberg Solutions was founded in 2007 in Lviv, Ukraine and has grown to a 200+ person team with additional offices in Hamburg, London, and Kraków. For a buyer evaluating who they'd actually work with, the firm's scale means dedicated engineers rather than shared generalist staff, backed by direct partnership status with NXP, STMicroelectronics, and Microchip and an in-house hardware lab the team uses daily for board bring-up. ISO 9001, ISO 27001, and ISO 13485 certifications reflect process discipline a hiring manager can expect from the assigned team, not just a company-wide policy on paper.

Zone7 Engineering

Zone7 Engineering is a Portland, Oregon electronics engineering practice founded and run by David Ashman, a senior electronics engineer with extensive experience designing digital and analog circuitry around various microprocessors and DSPs alongside embedded C/C++ firmware development. For a client evaluating the smallest possible version of an engineering-hire relationship, this is a firm where the person quoting the project, designing the architecture, and writing the firmware are the same single named individual.

Lemberg Solutions vs Zone7 Engineering: pros and cons

Lemberg Solutions
+ 200+ engineers give a hiring team dedicated staff rather than shared generalists spread thin across many clients
+ In-house hardware lab means the assigned team validates board bring-up itself rather than waiting on a separate department
+ Direct NXP, STMicroelectronics, and Microchip partner status is a credential the actual engineers on a project can draw on directly
+ ISO 9001, ISO 27001, and ISO 13485 certifications reflect process discipline built into daily team workflow, not just policy documents
+ Full IP and source code rights transfer to the client on delivery
- Does not run mass production in-house, so a manufacturing handoff still needs a separate team
- Does not handle regulatory certification filings on the client's behalf
- No published minimum engagement figure, so team-size and cost fit needs a direct scoping conversation
Zone7 Engineering
+ Founder-led model means the person quoting a project is the same person who designs and builds it, with no account-management layer
+ Covers project planning through PCB design, firmware, prototyping, and production readiness in one continuous process
+ Analog and digital circuit design experience alongside firmware covers mixed-signal product requirements
+ 15 years of practice predates many boutique competitors on this list
- Solo or near-solo team size severely limits capacity for a project requiring multiple concurrent workstreams
- Public case study detail and named client references are very limited
- No published pricing or minimum engagement figure
