About Us

In 1930, “Yip In Tsoi & Company Limited” was established with a registered capital of THB 150,000 and seven shareholders: Yip In Tsoi, Yab Long, Lenam Kin, Misiem, Kosoon, Kosoonlin, and Rhoy. The first board of directors of the company consisted of Yip In Tsoi, Yab Long, and Misiem. The company’s headquarter was located in Amphoe Ban Tawai, Phra Nakhon province. In 1938, the headquarter moved to Mahaprutharam subdistrict, Bangrak, Phra Nakhon province, which is the current location of the headquarter. With the visions and expertise in international affairs of the executives, the company had the opportunity to engage in trade with leading international companies, expanding and diversifying its business continuously. These included:

• Importing world-class quality products such as Texaco petroleum and petrochemical products, David Brown tractors, Isuzu trucks, bag sewing machines, and Air Temp air conditioners
• Importing high-quality consumer products such as Coleman fuel lanterns, Stabilo papers, Pelikan and Swallo stationery, 3M products, Rolleiflex cameras, etc.
• Insurance business and marine insurance
• Pioneering the chemical fertilizer trade in Thailand in 1946 by importing high-quality fertilizers from Germany under the trademark “Baimai”
• Partnering with Sissons Brothers Paint, the largest high-quality house paint manufacturer in the United Kingdom, to establish “Sissons Paint (Thailand) Limited,” a high-quality industrial paint production company
• Financial businesses, acting as representatives of “Siam City Bank” and “Bangkok Bank of Commerce” in the southern region and some provinces in the northeastern region
• Establishing “Yip In Tsoi Investment & Securities Ltd. – YISCO” and “Yipintsoi Finance Limited. – YIPFIN” to operate in the financial and securities businesses (later renamed as “Finance One Public Co., Ltd.”)

Yip In Tsoi entered the technology business in 1954 by becoming a distributor of “Burroughs Adding Machines,” an advanced office mechanical calculator at that time. The “B Division” (abbreviated from “Burroughs”) was established in 1958 to cater to the popular demands of this specific product line.

In 1963, Tawat Yipintsoi, who had graduated with a master’s degree in business administration from Cornell University in the United States, began driving the technology business. He started with conducting research and development to create a Burroughs computer that could type in the Thai language, a significant challenge at that time. In 1973, the company expanded into the distribution and installation of mainframe computers, with Thienchai Lailert playing a crucial role in this business. The company’s notable projects included installing mainframes at the Kasikornbank, the National Institute of Development Administration, the Royal Thai Air Force, the Metropolitan Electricity Authority of Thailand, the Ministry of Finance, and the Thai Customs. The business expanded to include public and state-owned enterprise clients, leading to significant growth in Yip In Tsoi’s technology business.

In 1997, during the Asian financial crisis, the third-generation executives, Morakot Yipintsoi and Supak Lailert, had joined to strategize and lead significant changes in Yip In Tsoi. They introduced new, efficient technologies such as NetApp and products from SUN Microsystems to create new markets in the era when open systems were replacing the mainframe systems. They also collaborated with global business partners, aiming for a complete and comprehensive information technology business and expanding their customer bases from government and state-owned enterprise to finance, banking, and other industries.
