To create a company in New World, you will need to hit the company tab under the menu tab. You can reach this menu tab by pressing M on your keyboard. After hitting the correct key, you will be able to join a faction via the company menu to the top left of your screen.
However, you should note that you will need to be in a faction before you can join or create a company in the game. Luckily you can join one by just following quests or speaking to one of the faction representatives in a town.
That said, when you join one of the three major factions in the game, you will be able to create a company by going into the company menu under the company tab.
Under this tab, the game will ask you if you want to create a company, click yes, customize your emblem, choose a name, and then hit ok.
Once you finish, you will have just created a company and can now invite players to it and build up a large guild to complete PVP events and more.
You will also be able to claim territory in the game, but make sure you have a few members so that you can hold on to it and fight off rival companies and factions.
