Banatao was born on May 23, 1946 in Iguig, Cagayan, Philippines. His father, Salvador Banatao, was a rice farmer. His mother, Rosita Banatao, was a housekeeper.[2]
In 1984, Banatao and his business partner Francis Siu, founded a high-technology company, Moston, starting with a capital of half a million US dollars. Mostron was launched as a manufacturer of motherboards. They also hired Ron Yara of Intel as a company executive. After he developed a five-chip set, he co-founded Chips and Technologies in 1985. The company developed system logic chip set for IBM's PC-XT and the PC-AT. The company earned $12 million in its first four months. After 22 months, the company went public. In 1989, Banatao launched his third start-up company, S3 Graphics, with Yara in Santa Clara, California. S3 focused on enhancing the graphic capabilities in personal computers by using a graphic accelerator chip. The key to this was Banatao's invention of a local bus. The company had an initial public offering of $30 million. In 1996, the company became the leader of the graphic-chips market, beating a strong competitor, Cirrus Logic, Inc. In the same year, Chips & Technologies was sold to Intel for about $300 million.[9] In 2000, he decided to start his own venture capital firm named Tallwood Venture Capital with a capital of US$300 million, all of which came from his own pocket. He later sold another company for more than $1 billion, where it had less than 20 employees.[10] Dado was also part of SiRF, where it started the consumerization of GPS after it had been declassified by the US Government.
In 2010, Banatao became Ikanos Communications' CEO after Michael Gulett resigned as the company's CEO and President.[11]
Philanthropy
In the Philippines, Banatao through his Dado Banatao Educational Foundation,[12] annually awards five educational scholarships to intelligent Filipino students who have bright futures in the field of engineering and technology.[13] Also, with Philippine Development Foundation which he chairs, he is helping send brilliant young Filipinos to school to help them reach their full potential. PhilDev was spun off from Ayala Foundation's program.
[14] Through his Banatao Filipino American Fund, he assists Californian high school students of Filipino heritage who are pursuing a college education in engineering. He also built a computer center at his grade school in his childhood town of Iguig in Cagayan Valley, making it the only public school with the most modern computer network in the Philippines.[2]
