About me
Founder, Mladen Tošić
I founded Mount13 after over a decade at Bain & Company, where I was an Associate Partner and led transformations across EMEA and APAC. My focus: helping ambitious businesses solve complex challenges through bold strategy, marketing transformation, and guiding leaders through change.
My experience spans corporate strategy, customer experience, operating models, and commercial growth — from boardroom strategy to on-the-ground delivery. I’ve worked across sectors and with companies at every stage, from global brands to high-growth ventures.
I hold a PhD from the University of Cambridge and bring the discipline of academic thinking, the clarity of strategic consulting, and the mindset of a business builder. I partner closely with clients to unlock new possibilities — and drive lasting, measurable impact.
