JEETOO. The world's №1 AI recording card ODM
Voice is the entry point to AI
JEETOO is the world's largest ODM for AI recording cards — the vast majority of China's five best-selling brands run on our platform. Three proprietary algorithm stacks, inside a 3.1-millimetre card, built at a 99.9% yield.

Form factors
One platform. Every form a voice can take.
The card is where JEETOO became number one, not where it stops. The same controller, algorithm stack and app framework already take six forms — beyond the card: pin, pen, glasses, ring and badge, all available for sampling.

What we do
One thing, done to number one.
JEETOO does not build hardware that does everything. We build the one thing that hands real-world voice to AI — and that decision rests on three whys.
Why voice
The densest input humans have
People say far more in a day than they type. Voice needs no free hand, no interruption, no learning — it is the closest thing to a zero-friction interface.
So: the microphone lives in a card you already carry, not an app you have to remember to open.
Why recording
The precondition for personal context
Frontier models have converged on general ability. What separates them is whether they hold your context — and context does not appear on its own. It has to be captured continuously and effortlessly.
So: we build for continuous capture, not one-off recordings.
Why hardware
Software cannot reach real-world sound
An app cannot keep a microphone open all day, across meetings, calls, commutes and home. Only a physical device on the body can hand real-world sound to AI in full. That is physical AI.
So: JEETOO is a hardware company, not an app company.
By the numbers
Scale is a vote cast by the best brands.
China's five best-selling AI recording card brands each ran their own selection. All of them ended at the same supplier.

Technology
Hardware specs can be copied. Algorithms can't.
Three proprietary stacks, each answering one question: is it clean, did we get it, can you hear it. Together they represent eight-figure R&D, stable delivery to hundreds of thousands of users, and a bug rate near zero.
Stack · Acoustics
Acoustic modelling
Decides noise floor and dynamic range
Cavity and component co-tuning keeps the acoustic compromises of a 3 mm body to a minimum. The same microphone in an untuned cavity is a wasted microphone.
Stack · Pickup
Beamformed pickup
Decides whether you got it
Microphone-array beamforming reaches past 10 metres and keeps every voice in a multi-person meeting. Field and call recording are detected and switched automatically.
Stack · Noise
Noise reduction
Decides whether you can hear it
Wind, room tone, keyboards and HVAC are modelled and suppressed separately, so speech enhancement never eats the detail in a voice.
Co-developed with BES, the world's leading AI audio silicon
On the same silicon, others ship the reference design; JEETOO ships algorithms tuned with the chipmaker. Bone-conduction mics from Goertek, omnidirectional digital mics from Will Semi and Goertek — every critical part is first-tier. A parts list can be copied. A co-development relationship cannot.

Configurations
One platform, four product lines.
Shared controller, algorithm stack and app framework. Mic count, thickness, battery and transfer are combined to your price point and use case — no choosing between the expensive option and the one that works.
Six finished products from one platform — same controller, algorithms and app framework; different finishes, mic counts and brands

|---|---|---|---|---|---|
| Flagship | 5, incl. bone-conduction | 3.1 mm | 35 h | Wi-Fi ≈1 Mbps | Premium consumer brands, carriers |

Work
Three kinds of customer. Three kinds of scrutiny. All passed.
A top knowledge-media brand, a national carrier, an overseas private-channel brand — each vetted us by its own rules.

Seven stages. All under our own control.
From design to launch collateral, the whole chain closes inside JEETOO. Scale and control convert directly into three things for the customer: price, time and risk.

China supply-chain prices. World-class algorithms.
Half a million units of purchasing and line amortisation deliver a China supply-chain cost structure — but the advantage comes from scale and control, not from cutting the spec. A mass-market budget buys BES silicon, chipmaker-tuned algorithms and a five-mic array, still at 99.9% yield.
What a customer receives is not a drawing but a product already iterated through 500,000 real shipments — ready to scale on launch, with no trial period to sit through.
Company
Software first. Hardware to the top.
JEETOO proved itself in software first — 30,000 enterprise customers, Fortune 500 deliveries. Then it proved itself in hardware — 500,000 units in production, number one in the world. One company, two proofs. When the people who write the algorithms share a building with the people who climb the yield curve, what comes next is not limited to a card.
2017
Software · the first proof
Started in enterprise AI software. Over nine years, more than 30,000 companies — from Fortune 500s to regional leaders.
2021

Say hello
Have an idea that needs ears?
Recording cards are where we started, not where we stop. Rings, badges, ear-clips, pendants, glasses — or the thing you haven't named yet. If it's AI hardware that listens, we want to hear about it.
Tell us the idea. Algorithms, tooling and yield — that part is ours.
- A reply within two working days — from an engineer who read it, not a sales deck
- A configuration recommendation and a sampling plan in the first conversation
- Your idea stays yours. We just build it.
