has surpassed 10 million users worldwide. This profitable start-up has had a record breaking twelve months and increased revenues by more than 120% to $40 million in 2010. Rebtel’s figures show it is currently growing five times faster than Skype and plans to continue this trend by almost doubling its revenue to $75 million by the end of 2011 with a current run-rate of $55 million.

Rebtel has made significant strides since its inception in 2006 with over 1 billion minutes of international calls logged and a total of 200 million calls connected. The company attributes its success to its commitment to the customer and its dedication to innovation. Ten new hires were recently made in the research and engineering team to strengthen Rebtel’s mobile application credentials and deliver free and cheap international calls through iPhone, Blackberry and Android applications.

These award-winning mobile offerings have helped Rebtel to cement consumer loyalty, double its customer base in 2010, and achieve an all time high on its customer satisfaction survey in February 2011 with 98% of users stating they would recommend Rebtel to a friend. Rebtel’s word of mouth recommendations are an integral part of its growth, as it drives registrations and accounts for 65% of new user registrations.

Rapid expansion into Africa, Asia and the Middle East has also contributed to the increase in customer base. Free international calls to mobiles were enabled in Algeria, Bahrain and Jordan and rates have been lowered to Egypt and the above countries.
