Hong Kong corporate governance activist David Webb has died on Tuesday at the age of 60, according to an announcement made on his social media platform. "It is with great sadness that we share that David M. Webb MBE passed away peacefully in Hong Kong on Tuesday January 13th, 2026 from metastatic prostate cancer. David will be missed by family, many friends, and supporters. The family request privacy at this difficult time," a post on his X account read. Born in Britain in 1965, Webb moved to Hong Kong in 1991 as an investment banker. Several years later, he founded Webb-site.com — a free online site that offers stock market news and data while advocating for transparency as well as better corporate and economic governance. He's considered one of the city's most vocal activist investors whose investigations into corporate misconduct had triggered regulatory probes. In 2020, Webb revealed that he was diagnosed with metastatic prostate cancer and would step back from in-depth research on listed companies. As his illness progressed, he announced last February that he would shut down Webb-site.com and release the database for public download. Webb is survived by his wife and two children.
