Companies are the main instruments for materializing any resource or product in the game. Generally speaking, there are two groups of companies: resource group and products group. All companies have 5 levels for upgrading. Every company level adds an additional work slot for a new employee and their security status is increased.
Certain resources need certain factories, placed at certain locations where that resource is present. Example: If a player wants to produce Wood, they need a Wood factory, which must be built in a hexagon which has the Wood resource in it.

The main difference between what resource and product companies produce, is that instead of using natural resources as inputs, a product company uses already harvested or extracted raw materials, that must be present in a company warehouse for the production to happen.
