Lemberg Solutions vs Doulos: 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. Its firmware consulting practice covers platform and MCU selection, RTOS strategy, and architecture-level guidance delivered before a client commits to full development, backed by direct partnership status with NXP, STMicroelectronics, and Microchip and an in-house lab for hardware validation. ISO 9001, ISO 27001, and ISO 13485 certifications give an advisory engagement documented process credibility that a purely informal consulting relationship doesn't carry.

Doulos

Doulos was founded in 1990 and is headquartered in Ringwood, Hampshire, UK, with a North American base in Silicon Valley and a team reported between 11 and 200 employees depending on source. In 2022, the founders transferred ownership to the staff through an Employee Ownership Trust, and the firm has set what it describes as the industry standard for training and know-how across system-on-chip, embedded software and security, and AI and deep learning for more than three decades. For a buyer evaluating consulting relationships on longevity and independence from outside investors, the employee-ownership structure is a specific, verifiable signal.

Lemberg Solutions vs Doulos: pros and cons

Lemberg Solutions
+ Direct partner status with NXP, STMicroelectronics, and Microchip means MCU selection advice comes with chip-vendor-level engineering support behind it
+ Design-phase engagement is offered as its own line item, not only as a prelude to a locked-in full build
+ In-house hardware lab lets architecture recommendations be validated against real silicon before a client commits budget
+ ISO 9001, ISO 27001, and ISO 13485 certifications give an advisory engagement a documented process a client can audit
+ Full IP and source code rights transfer to the client on delivery
- Does not run mass production in-house, so a consulting engagement that leads to production still needs a separate manufacturing partner
- Does not submit regulatory certification filings on the client's behalf, only supporting technical documentation
- No published consulting day rate or minimum engagement figure
Doulos
+ 35 years of continuous operation and stated industry-standard status in SoC and embedded software training
+ Employee Ownership Trust structure since 2022 means the firm answers to its own staff, not outside investors, a stability signal for a long advisory relationship
+ Dual UK and Silicon Valley presence gives coverage across European and North American time zones
+ Training curriculum spans SoC design, embedded software and security, and AI/deep learning, a broader technical range than most pure-consulting boutiques
- Primary identity is training rather than hands-on firmware development, a narrower fit for a buyer needing implementation work alongside advisory guidance
- Reported employee counts vary between roughly 11 and 200 across sources, worth confirming current capacity directly
- No published pricing or minimum engagement figure
