Our history

Our history

Founded in 2011,
Sigma Connected employs over 5,000 people and operates across offices in the UK, South Africa and Australia.

Follow our journey…

…from being founded in 2011 with 20 full-time employees to our expansion as a global brand now providing services to blue-chip clients.

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 and McLaren Credit Services. We have also launched a new operation in 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.
