KUAI is the 43rd sign of I'Ching, the book of changes. It is a symbol of break-through and resoluteness.

During the spring of 1994 Kuai was the first company in Sweden offering dialup Internet connections to the public. The company was active until 1997 when dialup became a commodity among the large telcos, mostly due to favourable interconnection fees for terminating traffic. So In 1998 the focus was changed to web and server hosting services using the name Levonline, which is still an active part of the Loopia group owned by the Danish private equity fund Axcel.
