Hello. I am Seol Dong-yeol, CEO of STL Co., Ltd.,
a traffic safety specialized company that protects human safety through innovation.

Since our founding in 2019, we have not simply manufactured products we have been developing technologies that save lives.
From smart traffic lights to carbon-reducing, ground-embedded pedestrian signals, our continuous research and development efforts have resulted in over 40 patents and 35 certifications.
These achievements not only prove our technological excellence, but also stand as a promise to build a safer society.

Following our incorporation in 2021, we established a solid foundation for systematic growth by obtaining venture company certification, INNO-BIZ certification, ISO 14001 environmental management certification, and by founding a corporate R&D center.
Yet our greatest pride lies not in these accolades, but in the passion of our employees, who work late into the night every day, striving to create better safety technologies.

“One person’s safety, everyone’s happiness.”

This is not merely a slogan, but a philosophy deeply engraved in the hearts of all our employees.
Each day, as we imagine a child safely crossing the street at a signal we created, or an elderly person calmly walking across a crosswalk, we continue to research and develop better products and technologies.

In an era of rapidly changing traffic environments, we are taking the next step forward with human-centered smart traffic safety systems that integrate AI and IoT technologies.
We are also committed to leading the way in eco-friendly technology development for carbon neutrality and a sustainable future, growing beyond Korea to become a global leader in traffic safety system technologies.

As a reliable partner responsible for your safe and happy tomorrow, we will continue to repay your trust with unwavering innovation.

Seol Dong-yeol
CEO, STL Co., Ltd.
