ZYTO is a global technology company. We develop and produce software and integrated hardware products that have been specifically designed to provide insight into personal health and wellness decisions. ZYTO products accomplish this goal by using ZYTO scan technology.

The innovative ZYTO scan technology facilitates an interface between a computer and the human body. The resulting dynamic data exchange, known as a biosurvey, involves computer generated signatures called "Virtual Items" and recording the body's galvanic skin response, a well-developed method of monitoring stress responses that is commonly used in applications like polygraph tests and biofeedback.

ZYTO technology does not identify, diagnose, or treat any disease or medical condition.

In 1985, Dr. Vaughn Cook (founder and CEO of ZYTO) went to work for the Esion Corporation, the maker of the Interro biocommunication device. During his time at Esion, Dr. Cook worked in both sales and training and became familiar with every aspect of technology-based biocommunication.

In 1988, Dr. Cook left Esion to start a company named Digital Health Corp. There he developed an innovative computerized EAV system he called the Omega AcuBase. The Omega AcuBase was the first system of its kind to be registered with the U.S. Food and Drug Administration (FDA).

In 1997, Dr. Cook sold this technology to the BioMeridian Corporation, and for a short time worked for BioMeridian in sales, training, and eventually as its president. However, Dr. Cook left BioMeridian in 1998, choosing instead to focus his efforts on Digital Health’s core business.

In 2001, Dr. Cook independently began development of what is now ZYTO technology, and began selling the technology in late 2004 through Digital Health. At the end of 2004, he organized Zyto NV, and transferred his technology to the new organization including the ZYTO Hand Cradle, the initial software package, and the methods for programming computerized stimuli known as Virtual Items.

During the last 25 years, Dr. Cook has been continuously involved in the development and sale of biocommunication technology. During this time, he has also been actively involved in clinical practice as the owner of Utah Acupuncture Clinic and the Meridian Health Center in Salt Lake City, Utah. This clinical experience has strongly influenced the technology that Dr. Cook has developed and continues to develop in order to meet the changing needs of our customers.

Under the direction of Dr. Cook, ZYTO has continuously pursued product enhancements, further development of the technology, and a commitment to meeting the needs of our users. During the intervening years, we have released multiple new versions of the software and developed new market-specific applications such as the ZYTO Compass. We have also redesigned the original hardware, including upgrading the Hand Cradle with a cleaner, sleeker look and USB functionality. More exciting innovations are to come.
