Human Function Company
A world where no one
fears getting old.
RealDesignTech builds the technology that measures, understands, and improves Human Function — so people stay strong, sharp, and free for life. Ultiracer is where that begins.
Why we exist
We don't sell a longer life. We build a smarter way to age.
We are not a fitness, wellness, healthcare, or medical-device company. We are a Human Function Company.
Aging is natural. Functional decline is not. Everything we make measures, understands, improves, and predicts Human Function — so getting older becomes a continuation of growth, not a loss of freedom. We are starting the first Super-Ager civilization.
Our thesis
Aging is natural. Functional decline is not.
The conventional story says the body can only decline with age. We reject it. With the right measurement, training, habits, and data, function can hold — and keep rising. The distance between those two curves is the life we help people design.
Mission
To build a world where no one fears getting old.
Not simply a longer life — a life that stays functional. We extend the healthy years that come before medicine ever begins, and help people meet aging as a continuation of growth rather than a limit.
Vision
Create Super-Agers — and make them the new standard.
A Super-Ager is not a rare exception. It is anyone who understands their body and mind, keeps growing, and turns age into new possibility. Our goal is a world where that becomes the new standard of humanity.
What we believe
Seven beliefs
The principles behind every product, dataset, and decision we make.
Decline is not destiny
Aging is a natural process. Functional decline is not its inevitable result.
What is measured can improve
Human Function can be measured — and anything that can be measured can be improved.
Everyone can be a Super-Ager
Every person is born with the potential to age exceptionally well.
Technology extends people
Technology exists to expand human possibility, not to replace it.
Data is a language
Data is a way to understand people, not a means to control them.
AI for wiser choices
The point of AI is not to be smarter than people, but to help people choose more wisely.
Health is a daily practice
Health belongs to daily life, not the hospital. A healthy day is the best prevention.
Aging Smart
We empower people to design their body, their mind, and their life.
We don't manage your body for you — we help you understand it. We don't train your brain for you — we help you find its potential. We don't decide your life — we help you design it.
Body
Understand how you move and where you can grow, measured objectively.
Mind
Discover cognitive potential through active balance, steering, and focus.
Life
Design a longer, freer life on your own terms — not someone else’s.
From RealDesignTech to Ultiracer
RealDesignTech Co., Ltd. was founded in February 2018 in Suwon, South Korea, to turn indoor cycling from simple cardio into a complete brain-body training system for healthy aging. That work became Ultiracer — a platform that pairs proprietary hardware with software, data, and AI to make Human Function visible and trainable.
We sit where technology meets longevity, building products that help people stay healthy proactively rather than reactively. We don’t replace medicine — we extend the healthy life that comes before it, addressing the real barriers to exercise: time, motivation, and engagement.

What we do
We measure, understand, predict, and improve Human Function.
Our hardware, software, data, and AI work as one system. The bike is where it starts — not the point. The point is your function: made visible, made trainable, and made yours for life.
Measure
Capture how the body and mind actually perform, objectively.
Understand
Turn raw signals into a clear picture of your function.
Predict
See what is ahead and act before decline ever begins.
Improve
Train what matters, with guidance that adapts to you.
