Consider a patent Cooperation Treaty (PCT) Application:

This is better than filing directly via the Paris Convention since it will provide any startup with a unified procedure to file into the 126 member countries. A Patent Cooperation Treaty is an International patent law treaty. A patent filed under this treaty can be called a patent cooperation treaty application or an International Application. A Patent Cooperation Treaty application provides a startup with a more cost effective route if you want to file into more than just one or two countries .Apart from this a startup gets an additional time of 18 months before you can file into individual countries for protection. This will also provide time to refine its inventions and research the market.

Apart from simplifying the process of filing a patent application, it delays the expenses in the application for the protection of patents from other countries.

Also an inventor filing a patent application in one particular language and in one patent office can seek protection in up to 117 countries throughout the world.
