“At Intrado we provide highly innovative and dependable emergency communication services and technologies. Our pioneering technology solution is at the core of the nation’s 9-1-1 infrastructure and supports the delivery of over 260 million calls every year.

We work with Orthogone because they increase the velocity of our development projects. But, it’s about more than simply increasing the number of resources, it’s about achieving the right fit. This is not easy.

The quality of Orthogone’s engineers and their ability to quickly integrate with our team – technically, personally and professionally – means we don’t waste time sifting through endless lists of contractors who may not have what it takes. With Orthogone we get it right the first time, every time.”
