Duobay is a product development company for AI and IoT hardware. We work with US companies, from AI-hardware startups to product teams inside larger tech companies, and take a device from a dev-kit demo to working units.
What we build: schematic and PCB layout, embedded firmware, Bluetooth LE, Wi-Fi and LTE connectivity, audio and acoustics, enclosure design, and an optional companion app and backend deployed in the client's own cloud account.
Focus areas: AI recording wearables, health wearables, LTE-M and GNSS trackers and Bluetooth tags, audio and voice hardware, and AI companion and elder-care devices.
Project reviews happen in the San Francisco Bay Area; electronics, firmware and mechanical engineering are done by our engineering team in Shenzhen. An engineer replies to every project brief within one business day.

Processes and approach
How do you gather and validate client requirements?
Every project starts with a Feasibility gate: we review the client's brief, dev-kit demo and target use, then write the system architecture, chip and module selection, BOM estimate and a risk list. The client reviews and signs off on these before any board is designed.
How do you ensure alignment with client goals and business strategy?
Work runs in paid gates (feasibility, works-like prototype, small batches of 10 to 1,000 units). Each gate has a fixed quote, written deliverables and a clear stopping point, so the client decides at every step whether to continue.
How do you keep clients and stakeholders updated on project progress?
Clients get written updates and measured results (power, latency, RF and audio data) from the Shenzhen engineering team, with project reviews held from the San Francisco Bay Area. Firmware lives in the client's own repository from the first build.
What quality assurance practices do you follow?
Prototype units are bench-tested for power draw, wireless performance and audio quality before they ship, and results are written up for the client. Design files, firmware and test notes are handed over at every gate.
How do you identify and manage project risks?
A risk register is part of the Feasibility deliverables and is updated at each gate. The works-like prototype uses proven modules on a custom carrier board, so the client's model runs on the target silicon before money goes into custom miniaturization.
What kind of support or maintenance do you offer after delivery?
The client owns the source files, firmware repository and design documents at every gate, so they can continue with us or take the work elsewhere. We support small-batch builds and firmware updates after delivery.
