Sigong Tech Co., Ltd.
Sigong Tech designs and installs the high-tech audiovisual and stage systems inside theaters, museums, and control rooms.
Sigong Tech is a South Korean company that builds the invisible nervous system of a modern theater or a museum. It designs and installs the sound, lighting, video, and stage machinery that make a performance or an exhibit actually work. When you sit in a theater and watch a set piece fly in from the ceiling or a screen descend to wow the audience, there is a good chance Sigong Tech helped put that system in place and make it run smoothly.
The company makes its money from projects. A theater, a broadcast studio, a large exhibition space, or a public control room hires Sigong Tech to plan the whole audiovisual setup, supply the equipment, and install it. Because each project is different, most of the revenue comes from one-time installations rather than from selling a product you can buy off a shelf. It also provides maintenance and support to keep those systems running after the curtains go up. Its customers are typically the organizations that own or build these spaces, such as cultural institutions, broadcasters, and government facilities, and they pick Sigong Tech because it handles the whole job, from design to installation, rather than selling just one part. A big part of the business comes from the boom in South Korean cultural and entertainment spaces. As the country built out concert halls, media centers, and large public venues, Sigong Tech was there to wire them up. This gives the company a steady stream of project-based work, but it also means revenue can swing depending on how many big construction and renovation projects are moving forward at any one time. Project businesses live and die by the pipeline: when the pipeline is full the company is busy, and when it dries up the numbers drop.
Sigong Tech is a small company listed on the KOSDAQ exchange, and it has long been one of the go-to specialists for this niche kind of technical work in Korea. For investors, the key thing to understand is that it is a project contractor, not a subscription business. Its fortunes rise and fall with the pace of theater, museum, and media facility construction, and with how well it manages the cost and risk of complex installations. That makes it a bet on cultural infrastructure spending, not on a steady monthly fee.

BIG PICTURE
Only about half of Sigong Tech's shares trade freely, a sign of tight ownership
- 50.9% Shares available to outside investors
- 49.1% Shares held tightly by big owners
Free float measures the slice of a company's shares that outsiders can actually buy and sell. At Sigong Tech, just over half the stock is on the open market, with one individual reportedly holding 43% and the company holding nearly 6% of itself. That leaves a small pool of shares for a firm designing and installing theater and museum systems, so big trades can move the price more than at widely held companies.

Timeline
Korea's First Exhibit Business
While working abroad, Ki-seok Park saw exhibition halls far more advanced than anything back home, and the gap stuck with him. In early 1988 he started Sigong Tech in Seoul as South Korea's first company built purely around exhibit facilities — a bet that the country would soon want to show itself off. It was a strange business to start from nothing, but Park had seen the future and wanted to build it at home.
The Laser Show at the Olympics
The same year, the Seoul Olympics handed the young company its big break: a laser show at the 63 Building. Clients doubted the idea would work, but it did, and the buzz from that show poured business through the door. Not bad for a company that had just opened.
Listing on KOSDAQ
A decade later, Sigong Tech put its shares on the KOSDAQ market, turning itself into a listed company and giving it public money to grow with.
A Culture Subsidiary
It soon spun off a piece of itself into a subsidiary, Sigong Culture, a small step toward building out the business beyond single projects.
Awards at the Shanghai Expo
At the 2010 Shanghai Expo, its work on the Korea Pavilion's video section and the Korea Business Alliance Pavilion's science and technology exhibits won awards — proof the company could hold its own on the world stage.
Forbes List and a New Home
Praise kept coming: Forbes named it one of Asia-Pacific's best small and medium companies, and the head office moved to Seongnam, just outside Seoul. The little startup was now a grown-up company.
A New CEO Takes Over
In 2023, founder Park Ki-seok stepped aside and Kim Seung-tae took the top job — a generational handover for the exhibition culture company.
Busan's Expo Loss Hits the Stock
Later that year came a sharp lesson in hype. Investors had piled into Sigong Tech as a key winner if Busan hosted the 2030 World Expo, sending the stock up more than 13 percent in a day. When Riyadh won instead, the shares crashed over 21 percent — the company's fortunes tied, for a moment, to a city's bid.
The Belgrade Expo Contract
The company kept chasing world expos anyway. It signed a deal with KOTRA worth 8.8 billion won to build the Korea Pavilion for the 2027 Belgrade Expo, carrying its international exhibition work forward.
