Follow our journey…
…founded in 2011 with 20 employees, we have grown into a global partner supporting blue-chip clients across multiple sectors. Today, we celebrate 15 years of difference, and 10 years of pioneering offshore delivery in Cape Town, South Africa.
Since being acquired by the Digicall Group in 2016, we have grown rapidly into an award-winning company. In the process, we have added new capabilities such as our successful ReachOut service. We have also operated in the US and Australia.
Although we have grown, we are proud to retain the values we held from the start. We also remain relatable and accessible and have maintained our company culture of putting people first. This includes our clients, their customers, our employees and the people in the communities where we work.
