Buyer’s Guide
How to Choose an Embedded Firmware Development Company
Choose an embedded firmware development company on five tests: senior engineers do the actual work; the team debugs at the hardware level (SWD probe and oscilloscope, not just an IDE); “done” means verified on your hardware; they have shipped in your regulatory environment; and you own every line of source and every design file at handoff. Hourly rate is the least predictive variable — total cost is set by rework, not day rates.
How to choose
What to look for
Who actually writes the code
Ask for the pod by name before signing. If the impressive engineer from the sales call disappears after the contract, you bought a brochure.
Hardware fluency
Firmware shops without electronics depth blame the board when things stall. Ask how they root-cause a HardFault — the right answer involves a debugger and a scope, not a rewrite.
Definition of done
Passing CI is not a product. Look for firms whose acceptance is the device running its real function on hardware, through power cycles and fault conditions.
Regulated-industry evidence
If your product is medical or safety-critical, ask to see the shape of their traceability and V&V artifacts — not just a logo wall.
Handoff and IP
Source, schematics, documentation, and build system delivered into your repositories with real knowledge transfer. Lock-in is a design choice — make sure it isn’t theirs.
How Kyros compares
| Criterion | Kyros Engineering | Common failure mode |
|---|---|---|
| First conversation | Principal engineer asks about architecture and constraints | Salesperson quotes a team size |
| Staffing | Named senior pod, introduced before signing | Anonymous “resources”, swapped mid-project |
| Debugging stalls | Root-caused on hardware with SWD probe and scope | Blame the board, wait on your team |
| Milestones | Fixed-price, results-tied | Hours billed regardless of progress |
| Handoff | Your repo, your files, documented transfer | Dependence by design |
Frequently asked
What are red flags when hiring a firmware development company?
A quote without an architecture conversation, no named engineers, hourly-only pricing for defined scope, no hardware bench, and “done” defined as code-complete instead of verified on hardware.
Should I hire a US firm or an offshore firmware shop?
Offshore rates look 3–5× cheaper per hour and can work for well-specified, low-risk scope. For regulated devices, novel hardware, or anything needing bench time and fast iteration, domestic senior teams usually win on total cost after rework and communication overhead.
What questions should I ask on the first call?
Who exactly will write my firmware? Show me a board you brought up. What does “done” mean here? What happens when a milestone slips? Who owns the IP? A serious firm enjoys these questions.
How much should embedded firmware development cost?
A bounded piece of work — one board, one firmware deliverable — commonly runs $8K–$20K over three to eight weeks; full products run considerably higher and are best quoted phase by phase. Quotes far below comparable scope are usually missing verification, documentation, or seniority — the parts that prevent rework.
