Tluczek (pictured) joined the company three years ago from Kantar TNS South Africa and has been research director and team lead for two years.

InSites Consulting acquired Johannesburg-based Columinate in 2018 and the business rebranded as InSites Consulting South Africa earlier this year.

Columinate co-founder Pretorious has been appointed to a new global role as head of consumer connections within InSites Consulting, leading the company’s consumer network strategy. The networks include creative network eÿeka and consumer curator network Illume.

Pretorious will manage a team across Romania, South Africa, France and the UK, while maintaining a support capacity for the South Africa office and local clients.

Tluczek said: "Our team of research consultants in Johannesburg are supported by a wider group of industry experts all around the world. Together we will provide the best service to our clients across customer experience, branding and innovation."
