THEONE is a sustainable technology company that supports customer success through continuous innovation, proven quality,
and shared growth.

Dear Valued Customers and Partners,

Thank you for visiting THEONE.

Since our founding in 2010, THEONE has focused on delivering reliable technology in fields where failure is not an option.

From submarine inverters operating hundreds of meters underwater to autonomous robots requiring precision within a 2 mm margin of error,
our work has been built on the trust of our customers and on reliability proven in real-world operating environments.

THEONE is not simply a company that develops technology.
We are a technology partner supporting national defense, improving industrial safety, and enhancing energy efficiency through proven engineering and stable operation.

Looking ahead, THEONE will continue to uphold three core commitments.

  • First, we will continue to strengthen our core technologies.
  • Second, we will support our customers with validated quality and reliable performance.
  • Third, we will act responsibly toward people and society.

The 'O' in THEONE represents completeness.
That principle continues to guide how we develop, validate, and operate our technology.


We will continue to provide technology that is reliable in the field
and sustainable in long-term operation.


Thank you.

CEO Kyeonghan Jeon
