yeo jun-young: prain global founder and chief executive officer overview
Yeo Jun-Young founded Prain Global in Seoul in July 2000 as a one-man startup, building it into South Korea's leading independent public relations firm and the parent company of the Prain Consulting Group, ranked 73rd on the Global Top 250 PR Agency Ranking in 2021.
Who Is Yeo Jun-Young?
Yeo Jun-Young is the founder and chief executive officer of Prain Global Inc., a South Korean public relations company headquartered in Jongno District, Seoul. He established the firm in July 2000 at a time when South Korea's public relations industry had limited homegrown agency infrastructure and was largely served by international networks entering the market. Yeo has described starting Prain as a genuinely one-person operation, managing and executing PR services personally for both retainer and project clients while simultaneously handling daily company operations and developing the firm's early consultants.
Among Prain's earliest clients under Yeo's direct account management were South Korea's Blue House, the Presidential Office of the Republic of Korea, alongside Samsung Electronics and Nike, a client mix that combined the country's highest government office with two of the most recognizable global consumer brands operating in the Korean market. From that one-man start, Yeo grew Prain into the largest PR agency in Korea within just five years of founding, an unusually fast climb to national market leadership compared with most of the founders profiled across this series.
What Is Prain Global's Position in South Korean PR?
Prain Global is the parent company of the Prain Consulting Group (PCG), which operates as a group of PR and communications subsidiaries under Yeo's leadership. The firm's core services span public relations, advertising, artist management, and film distribution, a broader service mix than the traditional PR-only agency model common among South Korea's international competitors. Prain now employs more than 150 consultants and has handled over 1,800 projects since its founding, according to the firm's own account of its scale.
Why it works: South Korea's PR market developed later than the United States or United Kingdom's, leaving space for a domestic agency to build scale before global holding companies established dominant local footprints. Prain Global's move into artist management and film distribution let it capture entertainment-industry communications work that pure-play PR firms could not service directly.

What Awards Has Prain Global Won Under Yeo's Leadership?
Prain Global was named PR Agency of the Year in 2017 by the Korean Advertising and PR Practitioners Society. The firm also won a Gold Award in the Public Affairs category at the 2017 Asia Pacific SABRE Awards for its "Ga Na Da" campaign with Korea's Ministry of Health and Welfare, a low-fertility and aging-society awareness campaign. In 2016, Prain Global won a PRWeek Asia Silver award for its Southeast Asia PR Campaign of the Year, promoting Korean halal foods in Indonesia for the Korea Agro-Fisheries and Food Trade Corporation.
How Did Prain Global Reach the Global Top 250 Ranking?
Prain Global ranked 73rd on the Global Top 250 PR Agency Ranking in 2021, a placement that put a South Korean-founded firm inside a list historically dominated by US, UK, and European holding-company agencies. The ranking reflected Prain's growth from a single Seoul-based startup in 2000 into a firm managing government, corporate, and entertainment accounts across South Korea.
Why it works: Global Top 250 rankings are compiled from self-reported agency revenue and staff figures, so Prain's placement at 73rd signals a revenue base large enough to compete with mid-tier international network agencies rather than remaining a boutique domestic shop.

What Government and Corporate Campaigns Has Prain Global Run?
Prain Global has executed multiple campaigns for South Korean government ministries, including the Ministry of Health and Welfare and the Ministry of Culture, Sports and Tourism. The firm won a Korea Communications Grand Prize award for its "Hello Policy Project," an online viral video campaign for the Ministry of Culture, Sports and Tourism, and a Grand Prize at the Korea PR Association Awards for further government-sector work. Prain's current client roster spans an unusually wide mix of sectors, including Zespri Korea, Pernod Ricard Korea, POSCO, Alibaba, Electronic Arts Korea, Riot Games, Roborock Korea, Samsung, SK Telecom, and Daewoong Pharmaceutical, reflecting the same breadth across government, consumer, gaming, and pharmaceutical accounts that has defined the firm since its earliest Blue House and Samsung Electronics engagements.
Why Does Yeo Jun-Young Matter to South Korea's PR Industry?
Yeo Jun-Young built Prain Global during a period when South Korea, the fourth-largest economy in the Asia-Pacific region, had been left largely to its own devices in public relations infrastructure. His firm became the reference point for a homegrown Korean PR agency competing on the same award circuits and rankings as international network firms, a template since referenced by other Asia-Pacific market leaders profiled in EPR's Architects series, including Teiji Nishie of Japan's Vector Inc. and Yap Boh Tiong of Singapore's Mileage Communications. The speed of Prain's rise, national market leadership within five years of a one-person founding, distinguishes Yeo's trajectory even within that group of Asia-Pacific founders, most of whom built their firms over a decade or more before reaching comparable scale.
