Why a new name
What began with a clear focus on app development now goes well beyond it: we replace ERP and old systems step by step, develop tailored business software, connect ERP systems through interfaces, support businesses with process optimisation and use AI where it takes work off people’s hands.
The name App Ahoi no longer fitted that range. So the company is now called Asertion, and App Ahoi GmbH has become Asertion GmbH.
What we do fits in three sentences: Understand processes. Develop software. Connect systems.
What changes and what stays the same
In short: only the name.

Where the name comes from
Asertion derives from “assertion”, a term from software development. An assertion checks whether an expected condition in a program is actually met - and speaks up if it is not.
That is our standard for every piece of software we develop: it does what it should - and when something is wrong, you notice before your customers do.
Asertion is pronounced the German way: “Ah-sehr-ti-on”.
