Visionary tech innovator Dado Banatao dies at 79
MANILA, Philippines – Filipino technology pioneer Diosdado “Dado” Banatao died on Christmas Day, December 25, his son Rey confirmed in a Facebook post on Friday, December 26.
He was 79.
Rey Banatao said the Silicon Valley engineer and entrepreneur “passed peacefully…surrounded by family and friends.” He was five months shy of his 80th birthday and died due to “complications from a neurological disorder” that emerged later in his life.
“We are mourning his loss, but take comfort from the time spent with him during this Christmas season, and that his fight with this disease is over,” the family said, adding that details of a celebration of Banatao’s life will be shared in the coming weeks.
Banatao’s passing was earlier publicly acknowledged by former Department of Finance secretary Cesar Purisima, who described him as “a brilliant engineer, visionary tech entrepreneur, and a true pride of the Philippines,” and emphasized that his greatest legacy went beyond technology and into his belief in Filipino talent.
Banatao was born on May 23, 1946, in the municipality of Iguig in Cagayan province, to a farmer and a housekeeper. He often spoke of growing up poor in a farming town, walking barefoot to school and seeing education as his way forward.
He graduated cum laude in electrical engineering from Mapúa Institute of Technology, and received his masters from Stanford University before building a career in the United States that placed him in the heart of the semiconductor and personal computing revolution.
Banatao was among the engineers whose work helped make computers smaller, cheaper, and commercially viable.
Over his career, he contributed to major advances in semiconductors, networking, and graphics, including early Ethernet-related chips, PC system logic, and graphics acceleration technologies that became foundational to modern computing.
He went on to co-found several influential Silicon Valley companies, including Mostron, Chips & Technologies, and S3 Graphics — whose innovations, to put it simply, made computers more affordable and easier to use, accelerating adoption.
His work at S3 Graphics was a major influence on the development of PC graphics hardware that emerged in the early ‘90s. The company was the third most profitable tech company in 1993.
He is credited for key innovations including the first single-chip, 16-bit microprocessor-based calculator; first enhanced graphics adapter chip set; pioneered local bus concept for PC; and the first Windows graphics accelerator chip.
In a 2013 Rappler article, Banatao said he did not consider himself an inventor but rather an innovator. “Innovation is more important because innovation implies you are putting together a whole bunch of other elements beyond that one invention. Innovation implies industry,” he said.
That mindset, among other reasons, is perhaps why colleagues and profiles often compared Banatao’s influence to that of Silicon Valley’s most famous names such as Bill Gates or Steve Jobs. He had a mindset that combined engineering, systems thinking, and market realities to build products that actually shipped and scaled.
That philosophy shaped his demanding work ethic. In a 2016 Medium interview, Banatao described pushing teams through long hours when deadlines were tight, insisting that leaders stay alongside their engineers rather than manage from a distance.
In that interview, he said: “As the founder, I go around and still manage the company and tell the engineers, ‘Thank you for working hard, but are you capable of doing this?’ ‘Yes, I think I can.’ ‘What do you mean I think? This answer of ‘I think’ does not work. You better be sure because we have a schedule to meet.’ The percentage of success is very high as a result. As a CEO, tell them you’ll be there with them. That’s what builds the Valley.”
Later, Banatao transitioned into venture capital as a founding partner of Tallwood Venture Capital in 2000.
In 2011, Dado and his wife Maria established the Philippine Development Foundation (PhilDev) and the Dado Banatao Educational Foundation, which support science, technology, engineering, and mathematics or STEM education, and scholarships for Filipino students and entrepreneurs.
Banatao had been outspoken about the Philippines’ technology gap. In a 2015 interview, he said that many local IT programs were not up to global standards, arguing that the country needed deeper engineering and innovation capabilities — not just technology users, but technology builders. And through PhilDev, he sought to address that gap by creating access to world-class education and mentorship.
“I want to see the Philippine tech industry thrive before I die. That’s what we’re doing with PhilDev,” he once said.
The Silicon Valley pioneer also established the Asian Institute of Management–Dado Banatao Incubator in 2017, and funded the Center for Information Technology Research in the Interest of Society and the Banatao Institute at the University of California, Berkeley, wrote Newsbytes.
Banatao is survived by his wife Maria and their three children, Rey, Desi, and Tala.
His family invites the public to share memories and messages through a memorial website dedicated in his honor.
From rural Cagayan to Silicon Valley, Banatao’s life traced a path of persistence, rigor, and belief in people — an influence that continues through the technologies he helped shape and the generations he worked to uplift. – Rappler.com
