Quentin Griffiths, co-founder of online fashion retailer ASOS, has died in Pattaya, Thailand, after falling from the 17th floor of a condominium on 9 February, Thai police confirmed.

The 58-year-old Brit was found outside the apartment block by rescue teams.

Authorities said Griffiths was alone at the time, the apartment was locked from the inside, and there were no signs of forced entry. An autopsy revealed no evidence of foul play. Assistant Chief Constable Oliver Wright confirmed an investigation into the circumstances of Griffiths’ death has been opened.

Police also reported that Griffiths was involved in two ongoing legal cases, including a dispute with his Thai former wife over a business they had run together. Documents related to the lawsuits were reportedly found in his apartment. CCTV footage showed no one entering the flat prior to the fall.

Griffiths’ career and ASOS impact

Griffiths co-founded ASOS, originally called As Seen on Screen, in London in 2000 with Nick Robertson, Andrew Regan, and Deborah Thorpe. The retailer grew rapidly, offering a mix of own-brand and third-party products, and became one of Britain’s leading online fashion platforms.

He served as marketing director before leaving the company in 2004 but remained a significant shareholder for nearly a decade. ASOS expanded internationally and leveraged social media marketing, helping it survive the early 2000s Internet bubble. In recent years, the company has faced profitability challenges and stiffer competition from lower-cost rivals.

An ASOS spokesperson expressed condolences, while the British Foreign Office said it was supporting Griffiths’ family and in contact with Thai authorities.

“He was instrumental in ASOS’s early development, and we will always be grateful for his contribution,” the company spokesperson said.

Police in Pattaya continue to investigate the circumstances of Griffiths’ death, though officials currently see no evidence of foul play.
