Santie Botha, Group CMO of MTN, the largest telco in Africa, “I was the Global Chief Marketing Officer of one of the fastest growing telecommunications brands in the world, MTN.”

“We needed to put mechanisms in place to enable our marketing staff across 23 operations in AME to understand the brand across all its touch points and construct marketing plans that drove customer growth, revenue growth, ARPU growth and brand value in a consistent and results focused manner.”

“We utilised the approach constructed by Thomas over seven years to consolidate and strengthen the positioning of our brand and focus on what the respective opco’s must do to optimise their competitive positions.”

“Almost 90% of our marketing staff was taken through the conceptual approach devised by Thomas as the basis of how to become more
effective in their marketing.”

“In 2012 MTN became the first brand from Africa to feature in the Millward Brown Top 100 Global Brandz.” (After this it became the best-known brand in Africa, ahead of global brands like Coca-Cola)

Jonathan Proctor, founding CEO of e.tv, the largest TV station in South Africa, after that the CEO of Antenna Group in Europe and today the CEO of Primedia Broadcasting, “Thomas worked with me to launch e.tv from a permission-to-broadcast piece of paper into a national and internationally recognisable desirable brand within a matter of months.”

From Stephan Pretorius, CTO and member of the executive team of WPP, “Thomas has worked very closely with all our account directors, technical consultants and the leadership team to establish a much more strategic client engagement model, to ask bigger questions, to ladder all activities up to business value and, generally, to be more thoughtful about our clients’ business.

He led client strategy reviews and essentially coached all our client teams through the process repeatedly. He led the development of a strategic toolkit. He was also a prolific contributor to our thought leadership."

"He is a superb big picture thinker, has a “no-limits” creative mind and has a fantastic collaborative and engaging manner.”

"I can confidently say that Thomas fundamentally transformed our consulting practice and deeply impacted the approach and thinking of all the client-facing people at Acceleration."

Leading a team from Central Saint Martens on a garment fabric futures project, the team leader, Dr John O' Reilly, Head of the Masters in Innovation, said,“We feel very lucky to be working with you. I love the way you challenge the researchers, with your examples from professional life and your understanding of creative processes.”

“Honestly, one of the best sessions we've had in my time at UAL: CSM.”

“The students were truly inspired and your encouragement really added to their capacity for experimentation and the stamina that's needed for engaging with challenges and failure.”

From a previous client, an executive from NASDAQ listed company Mix Telematics, Hernus Vermeulen, "In my career I have had the privilege to work with one of the greatest strategic minds one can find. Despite his academic accomplishments, Dr Thomas Oosthuizen has the rare ability to read between the lines, understand "street-smarts" and is always up-to-date with the newest advances in whatever field of Marketing you can think of. This is a "killer" combination to have on your side.

His approach, demeanour and the way he presents himself is always with humility. But he has the rare ability to make anyone in a room, even the toughest of critics you can think of, be quiet and listen. This for no other reason than people knowing they are dealing with an expert, who will more than likely teach you something new, despite your own years of experience. His support, yet consistent challenging approach to not only be good, but GREAT at what you do will always be an ideal I will strive for."
