In 1995, Anton Mendoza and Siva Sanmuga were attending University of Waterloo's Civil Engineering co-op program. They met during one of their work terms, as they shared the same employer. While traveling in Anton’s car for almost one hour each way, they began to discuss starting a business together. The intention was to find developers overseas to work on software projects.

On one of Anton’s trips, one of the contacts informed him of their need for setting up a callback switch to process calls from emerging markets to Western countries. At that time, Siva introduced Mamoon Rashid to Anton. Mamoon, also a Civil Engineering student, had software development experience and was the leading brain in developing the first switch platform.

The first hardware was a 386 Tandy computer donated by Anton’s father. Mamoon developed the first callback switch and billing using Visual Voice software and a four-port dialogic analog card. This platform was used to provide telecom service to a dozen multinational companies. The founders operated part time for more than two years while still attending school. Immediately upon graduation in 1998, Anton started to work full time, becoming the first employee.

The company acquired about $15,000 in capital from the founders' families and used it to set up equipment at a collocation space in New York, buy a digital card, and pay deposits to carriers. And this is how it all started.
