Van Walwyk was most recently managing director of MI Pro UK, before it merged with MARSC to form QuenchTec. He has also held senior positions at GfK.

Nick Southwood has joined QuenchTec as UK sales director.

Shaw said: “From now on, Mark together with the experienced executive team will run the company and be responsible for QuenchTec’s day-to-day operations. Nick’s sales leadership credentials will ensure long-term growth. I know that the new team and the rest of the executive management team will do an excellent job and the company is well placed to move into 2018.”
