A ntti Herlin is a Finnish billionaire and the chairman of KONE Corporation, a global leader in the elevator and escalator industry. He is the great-grandson of Harald Herlin, who purchased the company in the 1920s. Antti has been the driving force behind KONE's transformation from a traditional industrial company into a modern, technology-focused global giant.

He took over the leadership of the family-controlled company in the 1990s and served as its CEO before becoming chairman. Under his stewardship, KONE has become renowned for its innovation, particularly in energy-efficient elevators and the use of digital technology for smart building solutions and predictive maintenance. Herlin orchestrated a complex restructuring of the family's holdings, which resulted in him gaining a controlling stake in KONE, a move that caused friction within the family but secured his vision for the company's future. He is consistently ranked as the richest person in Finland.
