An "AI Eye" for Every Factory
We are developing an AI that understands physical operations to eliminate the "invisible inefficiencies" plaguing manufacturing floors. Our vision is to bring AI to every factory—not just the large corporations—to break through the productivity wall.
The Problem: Invisible Waste Is Eroding Your Profits
Manufacturing managers grappling with labor shortages and rising costs desperately want to be more efficient, but finding out where the waste lies and which workflows are optimal is a monumental challenge. Traditional efficiency tools are expensive and complex to implement, leading to a reliance on "gut feelings and experience"—a costly dilemma.
Zeteoh's Solution: Data from Your Team's Phones
Our platform, TRAILS, fundamentally solves this problem.
Easy and Low-Cost
Your employees' smartphones become powerful sensors that capture the movements on the factory floor. No need for million-yen systems or months-long installations.
"See" to Fundamentally Improve
We turn qualitative observations into objective data, visualizing who, when, where, and how your team moves. This allows you to identify bottlenecks and inefficient processes for science-based improvements.
A Foundation for the Future
The data we collect serves as the bedrock for future AI optimization, predictive analytics, and automation. You can start transforming your factory into a smart factory today.
The Future Zeteoh is Building
We are bringing this technology to factories worldwide to fundamentally change how the manufacturing industry operates. Our mission is to ensure that every factory, from small businesses to large enterprises, can reap the benefits of AI and achieve sustainable growth.
