Notability
There are millions of companies and organizations in the world but very few are notable enough for Wikipedia.

Conflict of interest/advertising
If you are connected with the company/organization in some way, you have a conflict of interest and it will be difficult to write without it looking like advertising - which is not allowed on Wikipedia. Unless a company is very special for something, even a short description, such as on a social network or business directory, is a form of advertising. If the article does not meet the notability guidelines, it will probably be deleted. If your company is truly notable, someone else will write about it sooner or later. If you want to contribute to Wikipedia, you may wish to write a new page from the list at Wikipedia:Requested articles.
