Our mission

Sleep Freely. We want to solve sleep disorders around the world.

MaRI was founded to provide solutions that solve daily sleep-blocking factors in the most human-friendly way and solve the problems associated with sleep disorders.
Snoring reduces the sleep quality of the person and causes sleep debt.
Sleep debt not only reduces intellectual productivity but also leads to accidents and operational accidents in-vehicle driving due to drowsiness and decreased attention.
Sleep apnea also increases the risk of various serious illnesses such as hypertension, heart failure, arrhythmias, stroke, and diabetes.
In addition, many people are dissatisfied with the lack of sleep due to the snoring of their partners.
For people with sleep disorders, we prevent sleep disorder- related diseases by normalizing blood oxygen levels.
For bed partners, we provide good and quiet sleep and the partner’s health.
We solve solving the marital problem caused by sleep disorders in a human-friendly way in order to maintain and improve marital relationships
(Marital Relationship Improvement).
