Who we are
Onset Group started in Arusha in 2012 as a sole proprietorship — a business support entity. Our eye was on Arusha, but we went beyond the regions: in 2015 the headquarters moved to Dar es Salaam, and in 2016 the business was registered as a limited company, Onset Group (T) Limited.
Today Onset is a group of companies with several business lines — ATL and BTL marketing, events, human resource management, visual communication and the FIELDForce platform — serving clients nationwide, Zanzibar included.
