What the company or idea is
POSCO is a South Korean steel manufacturer founded in 1968 by the Korean government in Pohang. Construction of the Pohang plant began on April 1, 1970. Park Tae-joon assumed the presidency of POSCO in April 1968. He had received a special command from President Park Chung-hee in 1967 to establish Pohang Iron & Steel Co., and was assigned CEO in 1978.
How it actually makes money
POSCO makes money by producing and selling steel. Its revenue comes from bulk industrial sales, not consumer branding or services.
What works
POSCO achieved world-leading productivity and rose to fifth place among noncommunist steelmakers by the late 1980s — built on government mandate, not market demand. In 1988, the second-phase mill was completed in Gwangyang. POSCO became a global company within ten years of Park Tae-joon’s presidency and reached third place among the world’s steelmakers by 2010.
What does not
The claim that Park Tae-joon’s leadership alone explains POSCO’s success obscures the role of sovereign capital, protected markets, and geopolitical timing. Leadership cannot substitute for state backing.
What to take from it
State ownership enabled scale, speed, and insulation from market discipline — advantages no venture-backed firm replicates. In 1997, Seoul announced that it was going to transform POSCO into a private company. In 2000, full privatization of POSCO was completed.
Is it worth your time
Yes — as a case study in state-led industrialisation, not as a model for private-sector startups.
