How The Pirates Grew a Seafood Price Blog Into a ₩57 Billion Business: A Content-Led Trust Strategy

How The Pirates Grew a Seafood Price Blog Into a ₩57 Billion Business: A Content-Led Trust Strategy

The first product of The Pirates, the Korean company behind seafood platform Ineogyoju Haejeokdan, was not an app. It was a blog. In 2013, founder Yoon Ki-hong photographed fish at Seoul’s Noryangjin Fish Market and posted that day’s prices. A case study published by Korean startup outlet Mobiinside traces how that content-led growth strategy became a business with ₩57 billion (about $41 million) in 2024 revenue. The series notes it is based on public reporting and may not reflect the founder’s exact intent.

The numbers over 13 years

  • 2013: Price blog launched at Noryangjin
  • 2014: 100 partner stores; expansion to KakaoTalk, Facebook and YouTube
  • Monthly users: 100,000 in 2015, 500,000 by late 2019, 1.5 million in December 2020
  • Revenue: ₩45.1 billion in 2021, ₩57 billion in 2024; 174% average annual growth over seven years
  • Profitability: First monthly profit in December 2022, annual profit since
  • Funding: ₩36 billion cumulative through Series C

Principle 1: Free information, paid distribution

Yoon decided the core price content would never be monetized, arguing that heavy fees on consumers or merchants keep people away. Revenue instead came from distribution: buying seafood directly from producers and selling it to market merchants and consumers, connecting all three user groups.

Principle 2: Rebuild trust at every stage

Information trust

Accurate daily prices alone drove a surge in visitors. Merchants joined because the platform brought younger customers, and about 700 stores across Korea now publish business information.

Transaction trust

Vetted partner stores and direct sourcing carried trust into the purchase.

Delivery trust

The company began moving from third-party logistics to its own delivery network and in 2025 adopted ROOUTY, an AI route-optimization tool with real-time vehicle tracking. For fresh food, trust is ultimately decided at the customer’s door.

Lessons for marketers

  1. Ship content before product. Publishing the information customers struggle to find can validate demand. See Startup Marketing Before Launch.
  2. Separate where you create value from where you make money. Free content builds trust; revenue can come from somewhere else.
  3. Prioritize repeat visits over sign-ups. Daily prices gave users a reason to return. Habit formation is covered in Korea’s Fuel Payment App Race: Why Habit Beats Downloads.
  4. Define the next level of trust as you scale, from information to transaction to delivery.
