T homas Straumann is a Swiss billionaire and the grandson of the founder of Straumann Holding AG, a global leader in the dental implant industry. The company, founded in 1954, has become a dominant player in the fields of dental implants, prosthetics, and oral tissue regeneration. While he inherited his stake in the family's core business, Thomas has forged his own path as a successful entrepreneur and investor, particularly in the hospitality and medical technology sectors.

He is the founder and owner of the Grand Hotel Les Trois Rois in Basel, one of Switzerland's most historic and luxurious hotels, which he extensively renovated. He has also been a major investor in other medical technology companies, most notably the Swiss firm Medartis, which specializes in surgical implants for bone fixation. His wealth is a combination of his inherited stake in the highly successful and publicly traded Straumann Group and the value created through his own entrepreneurial ventures.
