Firmware Development Outsourcing for US Hardware Startups
FreeRTOS, Zephyr, ESP-IDF, and STM32 firmware, written around your actual hardware and tested on your actual board, not built from a generic template and handed back untested.
Firmware built around your hardware, not a template
- Real-time firmware on FreeRTOS, Zephyr RTOS, ESP-IDF, STM32 HAL, or bare-metal, matched to your product
- Peripheral drivers, communication stacks, and wireless integration (BLE, Wi-Fi, LoRa)
- Hardware-in-the-loop testing on your actual board, not just simulation
- PCB design and mechanical design available from the same team, if you need it
- Full source code and documentation handed off, no vendor lock-in
- High-mix, low-volume firmware work: one-off boards and short runs get the same process as a 5,000-unit product
Our Firmware Development Process
The same process whether we are writing firmware from scratch or taking over a project already in progress.
Codebase & Hardware Review
Your existing hardware and any existing firmware are reviewed before a line of new code is written, so nothing gets rewritten that does not need to be.
Architecture & Driver Development
Peripheral drivers, communication stacks, and the real-time task structure are built around your actual hardware, not a generic template.
Feature Implementation
Application logic, wireless connectivity, and any cloud or BLE/Wi-Fi integration are built and tested incrementally, not all at once at the end.
Hardware-in-the-Loop Testing
Firmware is tested on your real board, not just in simulation, catching timing and peripheral issues before they reach production.
Handoff & Documentation
Source code, build instructions, and a written handoff, so your team, or ours, can maintain it going forward.
Where This Firmware Work Applies
The stack changes by product, but the same real-time, hardware-tested discipline applies everywhere.
Connected devices and sensor systems, firmware written around the actual radio and power budget.
Smart devices and embedded interfaces, real-time firmware tested on the actual board.
Monitoring and automation hardware, firmware built for continuous, unattended duty.
Embedded control and sensing systems, firmware built to a documented, traceable process.
Embedded monitoring and communication hardware, firmware for vehicles and fleets.
Connected control and sensing platforms, firmware for buildings and sites.
What US Founders Ask Before Outsourcing Firmware
Do you write firmware for FreeRTOS, Zephyr, ESP-IDF, and bare-metal projects?
Yes. We work across FreeRTOS, Zephyr RTOS, ESP-IDF, STM32 HAL, and bare-metal firmware, matched to what your product actually needs rather than defaulting to one stack.
What does a firmware development engagement include?
Peripheral drivers, communication stacks (BLE, Wi-Fi, LoRa, GSM), real-time control, power management, OTA update support, debugging and test documentation, delivered as readable source code with build files so your own engineers can take over.
Will I actually get to talk to my engineer, or just a project manager?
You talk directly to the engineer writing your firmware. India Standard Time gives a real working-hours overlap with US morning hours, and every inquiry gets a response within 24 hours regardless, so a question never sits for a full day waiting on a time zone to line up.
How is a firmware engagement priced, fixed scope or hourly?
Projects are scoped and quoted up front from your requirements, not billed as open-ended hourly time. You know the cost and the deliverables before work starts, and a mid-project scope change gets a clear, separate quote rather than a quietly rising invoice.
Can you take over firmware on a project that is already in progress?
Yes. We review the existing codebase and hardware first, then scope the handoff so nothing gets rewritten that does not need to be.
Do you also design the PCB, or only write firmware?
Both, if you need it. Firmware, PCB design, and mechanical design are handled by one team, so hardware and firmware decisions get made together, not handed off between vendors.
How do you handle IP and source code ownership?
A non disclosure agreement and any written IP paperwork your project needs are signed before any code or design file is shared, and you own the source code and firmware IP outright on delivery. All development is done in-house by our own engineers, nothing is subcontracted to an outside vendor, so your code never leaves our facility or passes through any other party.
