eCorpOne’s brand logo mark, created with our corporate identity, consists of the following three key words.

“e”: Internet, information network, and electronic.
“C”: Corporation, and unity.
“O”: One, fusion, ring, and global.

“O” locating in “C” indicates unity resulted in growth of global fusion of “e” and “c”. Red line that spreads from left side of “C” forms “e”, and it implies acceleration of global fusion with the Internet and unity. The red line connected to “C” indicates highly concentrated energy produced by “C” is poured into “O” ceaselessly. “O” is almost contacting “C”, which implies strong relationship between unity and the global ring. The red line never stings “O”: it implies that growth of global fusion with “e” is not forced but gently supported.
