Which Austrian billionaire co-founded the energy drink company Red Bull? Dietrich Mateschitz co-founded Red Bull.

Mateschitz discovered Krating Daeng, a popular Thai energy drink, while traveling in Thailand for his marketing work. He partnered with its creator, Thai businessman Chaleo Yoovidhya, and adapted the drink for European consumers. Together they founded Red Bull GmbH in 1984; the branded drink launched in Austria in 1987.

Mateschitz owned 49 percent of Red Bull and transformed the company into a global marketing powerhouse. The brand became closely associated with extreme sports, Formula One, football and other high-energy events, helping distinguish it from ordinary soft drinks.

The main trap is Chaleo Yoovidhya: he was also a genuine co-founder, but he was Thai rather than Austrian. Mateschitz died in 2022, after which his son Mark inherited his stake. Thus the nationality clue makes Dietrich Mateschitz the single intended answer.
