CreoSG was established in 1997 and listed on KOSDAQ in 2002; the company changed its name from Curocom to its current name in 2024 alongside a biotech-focused business restructuring.
Its business is organized into a solutions segment, a distribution segment, a biotech segment, and a real estate operation and leasing segment.
The solutions segment supplies core banking solutions and frameworks as the domestic operator of the BANCS-K core banking system, having built next-generation systems for multiple financial institutions including Kookmin Bank, Woori Bank, and Hana Bank.
More recently, maintenance and migration work tied to previously built systems, such as the Hana Bank next-generation project, has formed a base for revenue.
According to a disclosure around May 2026, the company signed a supply contract with Samsung SDS related to the third phase of Woori Bank's mid-to-long-term IT infrastructure optimization, broadening its participation in financial-sector projects through cooperation with a large systems integrator.
The biotech segment, through subsidiaries such as Sumagen (now ImmunoVaxBio), is researching and developing infectious disease vaccines including the world's first whole-inactivated HIV vaccine SAV001, as well as an immuno-oncology pipeline, in cooperation with entities such as the International Vaccine Institute (IVI) and Alteogen.
In 2025 the company signed a material transfer agreement (MTA) with Alteogen to explore joint development of next-generation immuno-oncology therapies. The real estate operation and leasing business has expanded since 2024 as part of broader diversification.
In the core banking market, the company competes against large systems integrators such as Samsung SDS and LG CNS, but its ownership of the specialized BANCS-K framework is cited as a point of differentiation.
