The large-scale conglomerate is active in healthcare, energy, building and industrial systems, real estate, e-commerce, and transport; with 22% annual growth.

B.Grimm was founded in 1878 when German pharmacist Bernhard Grimm and his Austrian partner, Erwin Mueller, started a chemist’s shop, the Siam Dispensary, on Oriental Avenue off New Road. The shop, one of the earliest incorporated businesses in the country, prospered and it was soon appointed official pharmacist to the Thai royal family.

After going through the period of World War I to 1964, the company expanded its business areas, including engineering and equipment for healthcare, power generation, telecommunications, air conditioning, and mechanical engineering. In 1988, the group expanded into power generation, manufacturing, and real estate, and also forged joint ventures with some of the world’s largest corporations. In 1992, the company built new factories and work also began on another new head office. Soon afterward, B.Grimm expanded into power generation, bio-diesel production, and the lifestyle industry. The company has since expanded into power generation, which accounts for 80% of total revenues.

Especially in 2016, Her Royal Highness Ashi Kesang Choden Wangchuck of Bhutan agreed with B.Grimm to establish the Gross National Happiness Centre of Thailand. The agreement marks the world’s first Gross National Happiness Centre outside of Bhutan since being established in 1972. The Gross National Happiness is a measure of economic and moral progress that the King of Bhutan introduced in the 1970s as an alternative to gross domestic product (GDP).
