Our Business Ventures

In 1947, the vision for the JTKC Group of Companies was born with the establishment of Union Hardware. Through the years, a reactive culture of raring entrepreneurship and hard work has expanded JTKC’s investments and management in several industries including Real Estate, Hospitality Business, Financial Services, Mining, and Manufacturing.

By the early 1950s, Union Hardware had quickly earned the success that allowed Tiu Ka Cho to open one of the first nail factories in the Philippines, the Manila Steel Manufacturing Company. Goodwill Steel and Wire Company, and Goodyear Steel Pipe Corporation then followed in the early 1960s with the latter being the cornerstone of the JTKC Group of Companies’ steel manufacturing operations. 

The business has expanded to include Zhangzhou Stronghold in Xiamen, China. 

With his businesses flourishing, Tiu Ka Cho did not rest on his laurels and endeavored to expand into real estate. In the mid-1970s, he opened his first of serviced apartments called Dakota Mansion which was soon followed by Mabini Mansion in Manila, Amorsolo Mansion in Makati, and Boulevard Mansion in Manila. In 1990, the historic and famed Gilarmi Apartments along Ayala Avenue was added to the fold.

The real estate arm of the JTKC Group of Companies further grew with the birth of the Discovery brand which started with Discovery Suites in Ortigas. This was then followed by Discovery Country Suites in Tagaytay and Discovery Shores in Boracay, both leaving a lasting impression on its discriminating guests.


Today, the JTKC Group of Companies continues to diversify with the establishment of Sterling Bank of Asia and Iremit Inc. Sterling Bank of Asia is a new savings bank that opened on March 30, 2007 and aims to revolutionize the banking industry by offering a world-class and professional level of service by creating a strong sales culture and customer orientation. On the other hand, Iremit Inc. is engaged in the business of money remittance aiming to capture a significant market share in the inward remittances by Overseas Filipino Workers around the globe.
