Maciej Grzelak
Chief Product Officer at VikingCo Poland


"I’m a telco professional with an NGO background and a degree in philosophy. My work-related path is covering a lot of areas such as customer service, marketing, loyalty, post-sales customer relations, product development, and finally business development. I’m a technology enthusiast who believes that the biggest difference can be made not in the “what” but by the “how” area. Customer experience is for me the key to ensuring product success."
