Steve Chang: A Fu Jen Catholic University Math Graduate Who Sold Antivirus Software to the World

30-second overview: Steve Chang was born in 1954 and graduated from the Department of Mathematics at Fu Jen Catholic University, then went to the United States to earn a master's degree in computer science from Lehigh University.¹ In 1988, at age 34, he co-founded Trend Micro with Eva Chen in Los Angeles, focusing on personal computer software development.¹ In 1991, the company launched the PC-cillin antivirus software. On August 18, 1998, Trend Micro listed on the Tokyo Stock Exchange (ticker: 4704) and on Nasdaq the same year,² becoming the first Taiwanese software company to list in Japan. In 2007 he founded Social Ventures Taiwan, and in 2019 established the Ming-Yi Foundation.³

Fu Jen Catholic University, Not Tunghai University

Steve Chang graduated from the Department of Mathematics at Fu Jen Catholic University, then went to the United States to earn a master's degree in computer science from Lehigh University.¹ Many reports incorrectly state "Tunghai University Department of Mathematics"; this article takes the original Wikipedia entry as the authoritative source.

In the 1980s, as personal computers were just taking off, he keenly sensed the enormous potential of the software industry. At a time when Taiwan was dominated by hardware manufacturing and the software sector was still in its infancy, Chang's choice was remarkably forward-looking.

The training of a mathematics degree has a direct correspondence to information security logic: the core of information security problems lies in algorithms and statistical analysis, and the virus signature identification in antivirus software demands precision in pattern-matching logic, not just programming proficiency. This academic background is the fundamental reason Chang was able to understand software products at a technical level.

Starting Up in Los Angeles: At 34 in 1988, with Eva Chen

In 1988, 34-year-old Steve Chang and his wife Eva Chen co-founded Trend Micro in Los Angeles, focusing on personal computer software development.¹ In the early days of the startup, with limited funding, Chang wore multiple hats as programmer, salesperson, and customer support representative.

The choice to start the company in Los Angeles rather than Taiwan had clear market logic: in the late 1980s, Taiwan's software industry was primarily contract-based, lacking an ecosystem for developing consumer software. Los Angeles brought them closer to the North American market and provided access to the large personal computer user community within the Asian-American population. This choice of starting point was an early condition that enabled Trend Micro to later establish a simultaneous presence across North America, Europe, and Japan.

PC-cillin: The Entry Point into the Consumer Market

In 1991, Trend Micro launched the PC-cillin antivirus software, centered on basic virus scanning and protection functions. The product achieved success in Asian markets and built brand recognition in Europe and the United States.

PC-cillin's market strategy targeted personal computer users, opening the consumer market with a friendly interface and low licensing fees. In the early 1990s, computer viruses were just beginning to pose a real threat to ordinary users, and Trend Micro launched its product at precisely this inflection point, securing a position on the earliest demand curve for antivirus software.

(Note: It was only after the Smart Protection Network cloud security platform launched in 2008 that Trend Micro formally entered the cloud-based antivirus architecture. The 1991 PC-cillin was a traditional on-premises scanning product.)

Listing on the Tokyo Stock Exchange (4704): 1998, A First for Taiwanese Software

On August 18, 1998, Trend Micro listed on the Tokyo Stock Exchange (ticker: 4704) and also listed on Nasdaq the same year.² This was the first time a Taiwanese software company listed in Japan, raising capital for the company's growth while also marking a milestone in the internationalization of Taiwan's software industry.

Trend Micro's choice of Tokyo rather than New York as its primary listing venue had clear business logic: Japan was the Asian market with the highest personal computer penetration rate in the 1990s and one of the markets with the strongest demand for information security software. Listing in Tokyo helped Trend Micro build credibility among Japanese enterprise customers, driving deeper penetration into the Japanese corporate market in subsequent years.

Taiwanese software companies in that era generally followed the hardware contract manufacturing path. Chang's choice to focus on software and go directly to an overseas listing was a rare trajectory in the history of Taiwan's technology sector. The 1998 Tokyo listing was not merely a capital markets event—it was a powerful demonstration that Taiwan's software industry could "exist independently in international capital markets."

2008 Cloud Transformation: From On-Premises Scanning to Smart Protection Network

In 2008, Trend Micro launched the Smart Protection Network cloud security platform, integrating multiple protection technologies including file reputation assessment, web reputation assessment, and behavioral monitoring.⁴ This architecture enabled Trend Micro to achieve a major breakthrough in the enterprise information security market.

The technical transition from on-premises scanning to cloud-based protection occurred at a time when smartphones were just beginning to proliferate and the complexity of enterprise network threats was rapidly escalating. Trend Micro seized this window, using a cloud architecture to address the fundamental limitation of traditional antivirus software in real-time threat response; this was the second transformation Chang led the company through, moving from the consumer market into enterprise information security.

Social Ventures Taiwan and the Ming-Yi Foundation: A Mid-Career Turn

In 2007, Steve Chang founded Social Ventures Taiwan, focused on the social enterprise model: using business methods to solve social problems and connecting disadvantaged groups with the job market. In 2019, he established the Ming-Yi Foundation.³

The name "Social Ventures" draws from Laozi's "The highest goodness is like water" (上善若水). Chang chose to found a social enterprise while still leading Trend Micro's global operations. This pivot was not a post-retirement hobby but a long-term commitment developed in parallel with his information security business. From selling antivirus software to building a social innovation platform, the timing of his mid-career turn came earlier than most Taiwanese tech entrepreneurs' entry into philanthropy.

Common narrative → More precise reading: Chang is often described as "a representative figure of Taiwan's information security industry"—this framing is accurate but incomplete. His more precise positioning is: the first Taiwanese entrepreneur to successfully internationalize a software product. In an era when Taiwan's technology sector was dominated by hardware contract manufacturing, Trend Micro's path (software R&D, Japanese listing, global deployment) was the first successful model through which Taiwan's software industry defined itself.

🎙️ Curator's note: There is an aspect of Steve Chang's entrepreneurial path that is rarely discussed in Taiwan's tech history: he did not wait in Taiwan for the environment to mature, but instead took Taiwan's technical capabilities to Los Angeles, to Tokyo, to the world as a testing ground. This "go out first, then come back" logic is the fundamental reason Trend Micro became the first Taiwanese software company to list in Japan.

Trend Micro's place in Taiwan's tech history is not merely "a successful information security company"—it is the first case proving that Taiwan's software industry could exist independently beyond hardware contract manufacturing. The significance of this proof has only grown more weighty with each subsequent citation as Taiwan's software industry has developed.

The timing of his founding of Social Ventures Taiwan in 2007 (while his commercial enterprise was still at its peak) shows that his understanding of "corporate responsibility" went beyond the standard framework of "giving back to society after retirement."

There is another aspect of Trend Micro that is rarely discussed in Taiwan's tech history: it is one of the few global enterprises founded by a Taiwanese person, built around Taiwanese engineers at its core, yet not branded with a "Taiwanese company" label in its localized operations. This "invisible Taiwanese identity" is a competitive advantage, not a limitation, in the global information security market.

From the Department of Mathematics at Fu Jen Catholic University to founding a company in Los Angeles, listing in Tokyo, and becoming a global information security leader, Steve Chang's story is a precise distillation of the idea that "Taiwan's technical capabilities had to go out to find their market": he went out, and then came back with an even larger market.

Today, Trend Micro has offices in more than 50 countries worldwide and employs over 7,000 people. A Taiwanese software company of this scale was virtually a unique sample in an era dominated by hardware contract manufacturing, and it remains the most frequently cited case of successful internationalization in Taiwan's software industry.

The pivot in the second half of Chang's life, from information security enterprise to social enterprise, shows that he does not view entrepreneurship as a destination, but as an ongoing methodology for testing "what problems are worth solving through business means."
