History of ComponentOne

In July of 2000, APEX Software and VideoSoft merged to become ComponentOne LLC. With the combination of APEX Software’s Windows-based tools and VideoSoft’s development tools, ComponentOne was able maximize its strengths in the US and international markets. After twelve years of operating as ComponentOne and continued success as a leading component vendor in both the Microsoft Visual Studio and HTML5/JavaScript markets, ComponentOne was acquired by GrapeCity. ComponentOne and GrapeCity had a strategic relationship in overseas markets since 1994, with collaborative products being ranked as the top bestselling products in Japan. The acquisition of ComponentOne by GrapeCity positioned the company as the forerunner in the Visual Studio industry.  Together with a stronger team and increased resources, GrapeCity and the ComponentOne Studio products are positioned to lead and assist the development community.
