Company Profile

The Journey of Gaaiho

Founded in 1989, ZEON is in the PDF business for more than 25 years. We started out making publishing software, and then dedicated our attention to PDF (Portable Document Format) in 1993. There it began the evolution of our PDF software, trusted by businesses and professionals around the world. While the journey goes ever onward, we hope you’ll join hands with us and create more possibilities down the road.


Among the Best in the World

The Era of Gaaiho PDF

15 years after we give birth to the first generation of DocuCom, the Gaaiho era officially begins. This is also the time we introduce the revolutionary concept of “full-scale PDF editing” to the world.


Birth of Gaaiho

ZEON expands R&D capabilities and begins to develop business collaboration software, codenamed M1. The intriguing brand name “Gaaiho” shows up around this time as well. Here is the Backstory.


The Dynamic Duo

ZEON launches DocuCom PDF Gold which consists of a converter and an editor program—a unique formation that will be passed on to the future generations. It is also available in English, Chinese, French, German, Italian, Spanish, Dutch, Japanese, Korean and Portuguese.


First in the Business

We lead the market by releasing the first Asian PDF solution—DocuCom 2.0— in Japan. It is also the first PDF program to incorporate various language applications to be delivered and displayed in PDF documents in Windows environment.


World is the Stage

This marks the dawn of ZEON’s PDF business—DocuCom 1.0, the first to support DBCS Asian characters in Windows. We fly to San Francisco to showcase the software at the Seybold Seminars, the premier trade show for the desktop publishing and pre-press industry of that time.


The PDF Pioneer

ZEON establishes the R&D center in Beijing (back then, Peking), China. The first company to set foot on PDF technology in Asia Pacific. (PDF insider: this is also the year PDF specs are first released to the market.)


The Founding

ZEON is founded in Taipei, Taiwan, by T.C. Here the journey begins.
