Hello, Milanesa here with another guide!
This guide answers exactly that question.
The table below is designed to show the optimal company progression order, allowing you to invest your money as efficiently as possible throughout the development of your economy.
Companies have two types of upgrades: Automated Engine and Storage. This guide focuses exclusively on the Automated Engine. Storage is usually a poor investment; it should only be upgraded when it becomes a bottleneck for your production.
Each column represents a company, and each number indicates the level that company should be at during that stage. Follow the table from top to bottom, progressing one row at a time.
When a 1 appears in a new column, it's time to open a new company.
In the following rows, simply upgrade your companies until they reach the levels shown.
Once all companies reach the same level, continue to the next phase of the table.
In short: follow the rows in order. Each row represents the optimal state of your companies and the next step you should take.

I hope this guide helps you make better decisions and develop your companies as efficiently as possible.
If you have suggestions for improving the table or have found a more efficient strategy, feel free to share it with the community. Every contribution is welcome!
