The co-founder of Asos, Quentin Griffiths, has died in Thailand after falling from the 18th floor of a condominium.

Quentin Griffiths, a British entrepreneur and co-founder of the online retailer Asos, passed away after falling from the 18th floor of a condominium in Pattaya, Thailand, on February 9. According to a police investigator, Griffiths, aged 58, was alone, and the autopsy did not indicate signs of violence or forced entry.

Griffiths co-founded Asos in 2000, a company that rapidly grew to become one of the largest fashion retailers in the world, with celebrity clients such as Rihanna and Michelle Obama. He left the company in 2005 and went on to other startups, including Achica and EBTM. Thai police mentioned that Griffiths was involved in two legal proceedings, which may have contributed to his stress.
