Ekaterina Semeshina is a Fractional CEO and strategic operator with a hybrid background at the intersection of business, cognitive science, clinical psychology, and medicine. She spent the last decade advising Fortune 500 and multinational clients across IAT sectors on growth, product strategy, GTM design, organizational behavior, and customer decision-science — leading end-to-end strategic transformations and building revenue-efficient operating systems.
