Truth first.
We named the company after the thing we refuse to compromise. Every product, every paper, every line of code is accountable to it.

We find how things actually work, and build what acts on it. Today, the instrument is AI.
The name is the mission. Every product we ship is a truth delivered.

02Principles
What we are here to do.
Written down so we can be held to it. The mission, the order we go in, and the rules we keep on the way.
01
We intend to answer.
How a body works. How the world works. How nature works. How the universe works. People have asked for thousands of years. That is not a reason to stop. It is the reason to build.
02
In order.
Life first — the truth you can act on today. Then the world people live and work in. Then nature itself. Then past it. Nobody has reached the end. We are going anyway.
03
AI is the instrument, not the company.
Today, the instrument is AI. Tomorrow it is hardware, physics, chemistry, biology — whatever the question demands. We learn what it takes. We are not loyal to the equipment.
04
A wrong answer breaks something real.
We build things that act. A wrong answer does not return an error message — it hurts someone, or it is lost. That is why truth is the first principle and not the last.
05
Clarity over hype.
We say what we have. We say what we do not have. We do not borrow credibility from words like revolutionary, breakthrough, or AI-powered.
Life. The world. Nature. The universe. In order.
03Business
One hard problem at a time.
We pick a hard problem, find the truth of how it actually works, and ship the tool that delivers it. Done honestly. Done well.

The mission, in order. We are at chapter one. The rest stand open until they are true.
Where we are going.
01Chapter 01 · Life
HygiLink
The first truth we are shipping: the truth about your own body.
iOS and Android. Hygi reads the signals your wearable already collects against your own baseline, never a population average, and tells you in plain language what helps you, what hurts you, and where you are heading. Today that truth arrives through a watch. Sensing keeps moving closer to the body: rings, patches, and one day further in. Truths Lab builds the intelligence that makes sense of those signals for the people they belong to.

Open
The world.

Open
The universe.
We will say more when more is true.
05Research
What we are studying.
Research is how a chapter opens. It underwrites the products we ship, and we publish what we learn when it is load-bearing for someone other than us.
Research areas and notesChapter 01 · Life — active
R01
Applied computer vision
Models that work under the constraints of real environments: limited light, novel viewpoints, restricted compute. Every chapter of the mission needs machines that can see.
- Detection
- Robustness
- Domain transfer
R02
On-device inference
Compiling research models to hardware that exists today, and to hardware that exists in places where the cloud is the wrong answer. A wrist today. A machine at work — and places with no network at all — after that.
- Quantization
- Edge runtimes
- Latency budgets
R03
Evaluation methodology
Better measurements for AI systems in their deployed setting, not their benchmark setting. A wrong answer breaks something real. This is how we catch it before it acts.
- Field evaluation
- Failure analysis
- Across populations
R04
Longitudinal physiology
Modeling one body against its own baseline, over years: what normal is, when it shifts, and where it is heading. The population average describes no one in particular.
- Personal baselines
- Chronotype
- Drift detection
R05
Personal causal inference
Which habits move which signals, for one specific person. A pattern is not a reason — we study how to tell cause from coincidence inside a single life.
- Cause vs. correlation
- N-of-1 experiments
- Habit effects
R06
Signal to language
A finding is not delivered until the person it belongs to can act on it. We study how to say true things about a body in language people actually use.
- Plain language
- Text and voice
- Explanations you can act on

When a chapter demands physics, chemistry, or biology, those fields join this list.

Truths Lab
Truths Lab is built around one mission: find the truth of how things actually work, and build the tools and machines that deliver it. A small team, working in English and Japanese. Our research underwrites our products. Our products underwrite the next research.
The lab is operated by TRUTH Corporation (トゥルース株式会社), registered in Chiba. Truths Lab is the brand you'll see in every public context. TRUTH Corporation is the legal entity that signs. Both are us.
Small. Patient. Long term oriented. By choice.
The patience is the method. Truth takes time, and the company is structured to give it that time.
