Neck Consulting

There has not been a rehabilitation equipment specifically targeting neck muscle in South Korea, in spite of the fact that stiff neck may cause different types of illness. TwoFive Co., Ltd. is a pioneer in the field.

Neckth Power

Neckth Power is the first technology-integrated neck muscle training equipment. It’s not just for people who have been diagnosed with neck-related conditions — athletes and people at home can use it to strengthen their neck muscle.

Importance of Neck

Stiff or unbalanced neck can lead to other conditions, such as headache, rhinitis, or cerebrovascular diseases. The vascular and nervous system of the neck are of utmost importance due to the implication on the brain anatomy and cerebral function. The lack of adequate blood flow to the brain can cause multiple dysfunctions.

Company Introduction

TwoFive Co., Ltd. is a South Korean venture company that develops and manufactures fitness and rehabilitation equipment for the neck muscle and accompanying application software.

The Founder

Hyungjoon Kwun, CEO of TwoFive Co., Ltd., was diagnosed with neck disc a few years ago. At the time, he couldn’t find a medical device that suited his needs, so he has been working on research and development for a device that specifically focuses on treating neck pain and strengthening the neck muscle. He founded TwoFive in 2017 and is now preparing to launch Neckth Power.

Our Vision

Our vision is to become a pioneer in helping people worldwide become free from neck pain not only by treating existing conditions but also preventing it in the first place by strengthening the neck muscle with daily care and training.
