Our Story
Working in a multidisciplinary sleep team, eXciteOSA® co-founder Professor Anshul Sama, was deeply empathic with many of his patients who were struggling with conventional treatment options that had failed to change in the last two decades.

Professor Anshul Sama practices in the field of rhinology with a special interest in sleep-disordered breathing, frontal sinus surgery and endoscopic skull base surgery.

As a member of the Nottingham Sleep Centre, Professor Sama has established expertise in snoring and sleep disorders, which is recognised at international level.

Over the years Professor Sama came across many devices. All of which had problems:

They had to be worn during sleep
Many were invariably uncomfortable
Only treated the symptom, not the cause
Only effective when in use
Further disrupted the already poor sleep quality
Only temporarily alleviated the problem
Enslaved users to lifelong use
Wanting to disrupt this dependence on products that had to be worn during sleep, Professor Sama launched the initiative into developing the world’s first, unique daytime treatment for sleep-disordered breathing – eXciteOSA®.

Three years of devoted effort by many highly skilled professionals from sleep medicine, maxilofacial surgery, product development, medical engineering, software engineers and regulatory experts, has led to a simple, intuitive, non-intrusive and safe product that is clinically proven to treat the root cause of sleep-disordered breathing.
