Software solution company Excel Technology International (Hong Kong) plans to expand in the mainland and Singapore to tap vast growth potential, according to managing director Peggy Chan. Ms Chan said Excel planned to set up a software centre in the mainland's south and open representative offices in Shanghai, Beijing and probably Guangzhou. The company also planned to open an office in Singapore to look at investment potential elsewhere in Asia. It is understood that Excel plans a listing on the Growth Enterprise Market (GEM) by the end of the second quarter. Ms Chan declined to comment. She said the company had strong strategic partners, who would help expansion. They include Cheung Kong (Holdings), Singapore-based United Overseas Bank and its subsidiary UOB Venture. US based venture-capital firm ChinaVest is also a backer. Excel was established in 1988 as an information technology developer and systems integrator. Last Week, Excel formed a joint venture, i21, with iBusiness Corp, itself an e-commerce joint venture involving Cheung Kong (Holdings), Hutchison Whampoa, HSBC and Hang Seng Bank.
