Four entrepreneurs who studied
business administration at the Korea Advanced Institute of Science and
Technology (KAIST) have come into the spotlight as they founded a startup
producing a functional beverage, instead of getting high salaries from large
firms, the university said Monday.
They are Brewguru CEO Park Sang-jae, Chief Technology Office (CTO) Park Hoon,
Director of Strategy Choo Hyun-jin and Director of Customer Experience Kim
The CEO and the strategy director earned their masters of business
administration (MBA) at KAIST, and the CTO is doing an MBA at the university.
The customer experience director was awarded a Ph.D. at the university's school
of management engineering.

a year earlier, following the growing interest in healthier products among consumers
The chief executive, who served as a co-founder of a beer company after winning
several brewing competitions here and outside of Korea, aims to introduce
Brewguru's kombucha to consumers in the U.S. and China within the next five
He also wants more MBA graduates to start their own businesses.
"In other countries, 30 percent of MBA graduates set up their own
companies, but business founders who earned MBAs are rare in Korea," the
CEO said, citing the fear of possible failure as a reason for the rarity.
"Our society will not be able to sustain its development unless the number
of startups increases. We hope Brewguru becomes a good example of a startup
founded by MBA graduates in Korea."
He donated 100 million won to KAIST in May for students who seek to run their
