B.Grimm

B.Grimm is a Thailand-based, family-controlled multinational conglomerate whose origins date to 1878, when German pharmacist Bernhard Grimm and Austrian partner Erwin Mueller established the Siam Dispensary in Bangkok. The business initially operated as a chemist's shop and later became an official pharmacy supplier to the Thai royal family. Its early development coincided with Siam's modernization and the arrival of European engineering and industrial companies. By around 1900, the business had formed a partnership with Siemens, helping establish a long-running pattern of operating through technology, distribution, manufacturing, and infrastructure alliances. The Link family became central to the company's history after Adolf Link joined the business as a manager in 1903. During the First World War, Adolf Link's assets in Siam were seized because of his German nationality, and he and his family were sent to internment camps in India. The family returned after the war, and B.Grimm later rebuilt its operations in Thailand. New premises opened at Wang Burapha in 1928 under the patronage of members of the Thai royal family. Herbert Link reopened the company in Thailand in 1949, while his brother Gerhard developed the B.Grimm name in Europe and represented Thailand diplomatically in Germany. During the postwar decades, B.Grimm moved well beyond pharmacy and trading. By 1964 its activities included healthcare equipment, power-generation equipment, telecommunications, air-conditioning systems, and mechanical engineering. The company subsequently developed offices, warehouses, factories, and distribution capabilities, while maintaining relationships with international manufacturers. In 1988, Harald Link, who had joined the Thai business in 1978, led a major expansion into power generation, manufacturing, real estate, and joint ventures with global industrial companies. Energy eventually became the group's most important business area. The group's activities include electricity and steam generation, building and industrial systems, healthcare-device distribution, property development, digital financial comparison services, and transport infrastructure. B.Grimm Power, a major subsidiary, develops and operates gas-fired cogeneration facilities as well as renewable-energy projects in Thailand and selected neighboring markets. B.Grimm's industrial-systems portfolio has included Carrier air-conditioning products, Beijer refrigeration components, Siemens-related electrical systems, Hamon cooling towers, KSB pumps, and other equipment for factories, buildings, and infrastructure. Its healthcare activities distribute equipment from international medical-technology companies including Merck, Getinge, Siemens, and Carl Zeiss. B.Grimm has also participated in major Thai infrastructure and property projects. A consortium involving B.Grimm, STENCON, and Siemens built Bangkok's Airport Rail Link, connecting Suvarnabhumi Airport with central Bangkok. The group has developed the Alma Link and Dr. Gerhard Link office buildings and has pursued a large property project in Pattaya. In digital services, it became the majority owner of Masii.com, an online financial-products comparison platform launched in 2016. The brand's identity combines commercial enterprise with royal connections, philanthropy, cultural activity, and a stated commitment to social and environmental responsibility. Its logo is based on the prang of Wat Arun, reflecting the location of the original business near the Chao Phraya River and the importance of Thai historical symbolism. Chairman and chief executive Harald Link has also promoted polo through the Thai Polo Club and related charitable events. In 2016, B.Grimm agreed to establish a Gross National Happiness Centre of Thailand with Bhutanese royal patronage. B.Grimm remains an active, diversified group, although detailed consolidated information for the privately controlled parent is less publicly available than information for its listed power subsidiary.

B.Grimm traces its history to 1878, when Bernhard Grimm, a German pharmacist, and Erwin Mueller, an Austrian partner, opened the Siam Dispensary on Oriental Avenue near New Road in Bangkok. The pharmacy was among the early formally incorporated businesses in Siam and gained a royal appointment as an official supplier of pharmaceutical products. The company's early commercial model combined local distribution with international technical relationships. Around 1900 it partnered with Siemens, a relationship that foreshadowed B.Grimm's later role as a Thai intermediary, manufacturer, distributor, and infrastructure partner for multinational engineering businesses. Adolf Link joined the company as a manager in 1903, and the Link family gradually became central to its ownership and management. The First World War disrupted the enterprise. Because Adolf Link was German, British authorities seized his assets in Siam and interned him, his wife Erma, and their children in India. The family returned to Thailand after the war. In 1928, new B.Grimm premises were built at Wang Burapha on property associated with Prince Bhanurangrsi, and the opening was attended by King Prajadhipok and Queen Rambhai Barni. Herbert Link later restored the Thai business in 1949, while Gerhard Link remained in Germany for a period and developed the company's European presence. Gerhard was subsequently appointed Thailand's honorary consul and later consul general in Hamburg. B.Grimm's postwar transformation was gradual but substantial. By 1964, the company was active in healthcare equipment, power-generation technology, telecommunications, air conditioning, and mechanical engineering. A new office and warehouse complex opened on New Petchaburi Road in 1967. The family also became associated with charitable work; in 1975 Herbert Link's wife, Alma, received the Thai royal title Khunying in recognition of her work with charitable foundations. Harald Link joined the Thai operation in 1978 after education in Germany and at the University of St. Gallen. From 1988 he led an expansion into power generation, manufacturing, real estate, and additional international joint ventures. The company built factories and began work on a new head office in the early 1990s. It also entered biodiesel, lifestyle activities, and other sectors, although power generation became the group's dominant business by revenue. B.Grimm Power was established on 26 July 1993. Through projects and partnerships, it developed gas-fired cogeneration plants supplying electricity and steam to national grids and industrial customers. Its activities later extended to wind, solar, hydroelectric, and biodiesel projects. The subsidiary has operated in Thailand and participated in power projects in Laos and Vietnam, including through Amata Power, a joint venture involving Amata and Sumitomo Corporation. Beyond energy, B.Grimm maintained a broad industrial portfolio. Its building and industrial-systems businesses included Carrier air-conditioning, Beijer refrigeration components, Siemens electrical technology, Hamon cooling towers, KSB pumps, and related equipment. Healthcare operations distributed medical devices from international manufacturers. The group also developed Bangkok office properties, pursued a large Pattaya development, and participated in the consortium that built the Airport Rail Link between Suvarnabhumi Airport and central Bangkok. B.Grimm entered digital financial services through majority ownership of Masii.com, launched in 2016. In the same year it helped establish Thailand's Gross National Happiness Centre with Bhutanese support. B.Grimm Power was listed on the Stock Exchange of Thailand on 19 July 2017 under BGRIM. The parent group continues to be associated with the Link family, while Harald Link serves as chairman and chief executive. Polo, philanthropy, heritage, and environmental themes remain visible parts of the wider B.Grimm identity.
