Who we work with
About me
Founder, Mladen Tošić
With over 15 years of top-tier consulting experience, I founded Mount13 to help businesses unlock their potential through personalized strategic leadership, transformation leadership and marketing transformation. As an ex-Associate Partner at Bain & Company, I’ve led major transformations across industries—working with companies in London, Sydney, Amsterdam, and Dubai. My expertise spans corporate strategy, marketing, customer experience, operating models, and due diligence, with a proven track record of driving growth and delivering results for my clients.
Educated at the University of Cambridge, where I earned a PhD in International Studies, I’ve also held leadership and advisory roles with prestigious institutions and innovative start-ups. I’m passionate about partnering with management teams to develop bold strategies, achieve sustainable growth, and lead meaningful change.
