Company registration can be completed in 1 day under ease of doing business. Therefore it is suggested to launch after incorporation. There are different rules for private companies and public companies and it is not clearer which company you would be incorporating.

tht 1 day registration is just a joomla i hv already applied 7 days before aur still aiting for approval of name. if i launch my site today and later on i will include my site business under same company. how far it cn be ok. In any case i dont want to miss this date of launch.

Assuming if it is only launch and no commercial transaction involved you can do it, but doing commercial transactions on that website without an incorporated company is not advisable.
