As a business presentation designer, I love to work with business presentations, full of financial data, detailed tables, serious graphics and transform them into infographic custom designed slides. Someone likes to create designs with creative pictures and impressive photos, my beloved tools are good structure, cutting unnecessary wise usage of icons and sometimes perfect photos to visualize the concept.
I would call this style "minimalist presentation design", though the maximal amount of information on business slides does not allow to do it. It is completely reasonable as a business decision needs detailed arguments and 360-degrees overview. It is often called the infographic style of slides, but infographic is one separate picture which tells a story and presentation is a sequence of slides so it is not 100% true.
But as a result you will obtain definite conceptual, laconic, as much minimalistic as possible, modern and creative slides with elements of infographics.
