Who We Are.

Opto 22 was founded in 1974 by engineers who designed a better solid-state relay and chose to build it in a non-corporate, flat organization. Now, over 40 years later, we're still privately held, lean, and run by engineers.

Our flat organization fosters individual responsibility, quick response to customers' needs, and fast development of cutting-edge products.
