Why Duobay

The speed of a Shenzhen team. The terms of a US company.

Each promise links to the page with the actual terms and its limits.

Every source file is yours

CAD, schematics, layout, firmware, app code and test procedures, handed over at every paid gate.

How ownership works →

Exit at any gate

Each stage has a fixed scope and price. Stop whenever the data says stop, and keep everything.

The gates →

One landed price

Unit quotes include freight, duties and tariffs, delivered to your US door.

How we quote →

Certification, planned

FCC, PTCRB, carrier and Bluetooth paths mapped before the first board, filed in your name.

FCC planning →

Your cloud, your keys

No China-hosted service in the data path. Audio and health data reach only your endpoints.

Data sovereignty →

A US contract

Aximora Labs Inc. signs under US law. Reviews in the Bay Area, engineering in Shenzhen.

Engagement terms →
How it works

Prototype. Pilot. Production.

Three stages, five gates, a fixed price for each. You see working hardware before you commit to the next one.

  1. 1

    Prototype

    1–2 weeks + 3–6 weeks

    Feasibility, then 3–5 works-like units on your target silicon, with power, RF and audio numbers you can check.

  2. 2

    Pilot

    10–1,000 units

    Your first custom PCB and enclosure, reliability tests, certification, and a pilot build for real users.

  3. 3

    Production

    1,000+ units, DDP

    Rolling forecast, QC report with every lot, delivered to your warehouse with tariffs paid.

Every deliverable, gate by gate →

Questions

Who owns the IP and source files?

You do. Designs, firmware, app code and documents made for your project are assigned to you when each gate is paid, and handed over at every gate. How ownership works.

Do you build the companion app and cloud too?

If you want us to. By default we deliver the device, its firmware and an SDK. As an option we build the iOS and Android app and the backend, deployed in your own cloud account. App, cloud and AI.

What is the minimum quantity?

Builds start at around 10 units. Pilot runs of 10–1,000 units are normal for us, not an exception.

Does any of our data go through a cloud in China?

No. Devices talk to your cloud or a US region you choose, and we deliver firmware source and an SBOM so you can verify it. Data sovereignty.

Have a dev kit and a deadline?

Tell us what the device must do. An engineer replies within 2 business days with questions, not a sales deck.
