Theta Technologies, Co-Owned by Richard Daab and Michael Stevens, Has been selling light and sound machines since 1991. The first light and sound machine in the Theta product line was the 36-Program Voyager. Seeing the need to reach the greatest number of people, Theta chose network marketing as a sales vehicle. This approach put them in contact with many thousands of customers, which allowed them to receive direct feedback about the kinds of features and sessions users wanted most in a light and sound machine. Theta’s Research and development in the 90', Which included partnering with many of the world’s Leaders in neurotechnology, Helped establish light and sound as the effective, Safe and affordable means of self development it is today.
