Jisup Lee, the founder & President of Ego Inc. designed and developed in 1997 a compact semi-submarine. His idea was to get everyone to easily enjoy the underwater environment and finally released EGO – compact semi-submarine in 2008. This magical item was the first in the world and patents and PCT were issued.

In 2009 Raonhaje Inc. was established to produce EGO and then in 2012 EGO Inc. was newly registered to set up mass production and a systematic research & development system. The existing compact semi-submarine has been altered and upgraded to release a much safer and stable SE 450 than ever before.

EGO Inc, with a better understanding how to enjoy the ocean, endeavors to keep developing various upgraded lines, in order for passengers to have a wide range of choices.

We pursue perfection in quality, absolute satisfaction, and revolutionary performance.
We provide passengers with New Marine Culture and Fun never experienced before.
We constantly grow as a world frontier company with a creative mind and sustainable development.
