Harald Link is a Thai-German businessman, the billionaire Chairman and Chief Executive Officer (CEO) of B.Grimm Group, a massive diversified industrial conglomerate in Thailand. Born in Basel, Switzerland, in 1955, his family's industrial legacy, B. Grimm, was acquired by his paternal grandfather in 1914.

Link received a strong education, earning an MBA from the University of St. Gallen in Switzerland. He moved to Bangkok, Thailand, in 1978 to join his uncle in managing the family firm. His career is defined by his commitment to modernization, sustainable energy, and the long-term development of the Thai economy, where he holds Thai citizenship.

Harald Link became Chairman and CEO of B.Grimm in 1987. His strategic vision transformed the company into a major regional player in energy, industrial systems, healthcare, and real estate. His most significant achievement was the founding and IPO (in 2017) of B. Grimm Power PCL (SET: BGRIM), the Group's power unit.

Under his leadership, B. Grimm Power became a major regional player in renewable energy, executing projects in hydroelectric, solar (including Southeast Asia's largest solar energy plant in Vietnam), and wind power. Link has received major honors, including the Federal Cross of Merit First Class (Germany) for aiding German-Thai trade and an honorary doctorate in Business Administration. He serves as President of the South-east Asian Equestrian Federation and actively supports science education in Thai schools.

Harald Link's social impact is massive and structural, tied to B.Grimm's role in driving Thailand's energy transition toward renewable sources. His company provides thousands of stable industrial jobs and critical infrastructure.

His major philanthropic project is the Little Scientist House, a German program for science education taught in more than 13,000 Thai schools. He is also involved in environmental conservation, partnering with the World Wildlife Fund (WWF) to aid Thailand's tiger population recovery.

Harald Link maintains the professional, composed style of a Thai-German industrial executive. His attire is consistently formal and high-quality, favoring tailored business suits or traditional Thai formal wear. His aesthetic reflects stability and confident authority, blending European and Asian corporate cultures.

Residing in Bangkok, Thailand, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to industrial scale, sustainable energy development, and his commitment to Thai civic life and equestrian sports.
