Lemberg Solutions vs QuEST Global: overview
Lemberg Solutions
Lemberg Solutions is a 200+ person embedded and full-stack engineering firm founded in 2007, headquartered in Lviv, Ukraine, with additional offices in Hamburg, Germany, London, United Kingdom, and Kraków, Poland. For an RFP evaluator, the relevant service-scope detail is that Lemberg offers all three standard engagement models — technical consulting, team extension/staff augmentation, and end-to-end product development — under a single ISO 9001/ISO 27001/ISO 13485-certified quality system, spanning electrical engineering, PCB design, firmware, embedded Linux, FPGA, connectivity, edge AI, and cybersecurity. Named semiconductor partnerships (NXP, Microchip, STMicroelectronics as primary partners) and a documented in-house hardware lab back the technical claims, and named clients (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) give procurement teams checkable references. Full IP and source code transfer to the client on delivery, a standard RFP requirement this firm meets without qualification.
QuEST Global
QuEST Global was founded in 1997 and is headquartered in Singapore, operating over 90 delivery centers across 18+ countries serving aerospace and defense, automotive, energy, hi-tech, healthcare, rail, and semiconductors. Reported employee counts vary substantially by source (roughly 21,500 to over 32,000), which is itself worth noting in an RFP due-diligence checklist — a firm this size and this diversified doesn't lend itself to a single precise headcount figure. Embedded and silicon engineering is offered directly to chipmakers as part of end-to-end services, one capability among many verticals rather than a dedicated specialty.

Lemberg Solutions vs QuEST Global: pros and cons
| Lemberg Solutions | |
|---|---|
| + | All three standard RFP engagement models (consulting, staff aug, full delivery) available under one certified vendor, simplifying multi-lot procurement |
| + | ISO 9001, ISO 27001, and ISO 13485 certifications map directly to common RFP compliance requirements for medical, security, and quality-managed programs |
| + | Named semiconductor partnerships (NXP, Microchip, STMicroelectronics) plus a documented hardware lab support technical due diligence |
| + | Full IP and source code transfer on delivery — a standard RFP requirement met without exception clauses |
| + | Named, checkable references (Astronics, Caltech, Speede, Ferno, Cellink, Bosch Rexroth) support procurement reference-checking |
| - | Does not manufacture at scale — RFPs requiring a single vendor through mass production will need a separate manufacturing partner |
| - | Does not carry regulatory certification itself — provides documentation and support, but the client retains ownership of the certification process |
| - | No published rate card or minimum engagement figure — budget qualification requires a direct RFI or discovery call before a formal RFP |
| QuEST Global | |
|---|---|
| + | 90+ delivery centers across 18+ countries support very large, globally distributed RFP programs |
| + | End-to-end silicon and embedded engineering services offered directly to chipmakers, not just downstream product companies |
| + | Broad vertical coverage means one vendor can support embedded RFP lots across multiple business units |
| - | Reported employee counts vary widely by source, making exact capacity harder to verify for RFP scoring |
| - | Embedded/silicon engineering is one capability among many verticals rather than the firm's central specialization |
| - | Scale and process overhead of a firm this size may be a mismatch for small, fast-moving RFP lots |
