Can you tell me what is the leading company in web hosting?

There are many hosting companies in the world, you should never have any kind of problem with hosting.

If you ask me, I think hostforweb.com (https://hostforweb.com/) is one of the best solutions available on the web.
It is flexible. Your sites will be always online and your host will not get on your nerves.

There are so many of them, not sure someone can name you the leader.
