AI Rollout at a Mid-Sized Company: What 5 Real Cases and the Data Show

One 2025 study says 95% of rollouts fail. Another has three quarters of companies already seeing a return. Same year, same subject. This post is not the story of an invented company: it looks at documented cases and measured research — including the places where they contradict each other.

Case Study: How We Built Our Own Agent

Case Study: How We Built Our Own Agent

Close to twenty AI tools running side by side, and whatever one of them learned, the next had never heard of. That is where EYAS came from. This post is not a feature list: it shows the decisions, the trade-offs we said out loud, and the one measurement that threw a finished-looking solution out of the window.

Document Processing and Accounting with AI

Document Processing and Accounting with AI

One question decides whether invoice scanning is worth it: **does the tax authority give you back your supplier's data, or only your own.** In Hungary it does, in Spain it does not — and that makes the same software redundant in one place and the only input in the other. Here is the formula to work it out: at a fifteen-euro hourly cost the credit pays for itself at **29 seconds** saved — so price is not the question.

AI Inside Your ERP: What Can the Built-In Intelligence Actually Do?

AI Inside Your ERP: What Can the Built-In Intelligence Actually Do?

The first question is not what it can do but whether it is there at all: **Community has no AI, Enterprise 18 has none either, 19 has it — but the default assistant cannot modify data.** What is there is not an Odoo model either: OpenAI or Gemini runs behind it, and on your own server your own key is mandatory. The vendor publishes no accuracy figure anywhere.

Copyright and AI: Training Data, Output, Your Rights

Copyright and AI: Training Data, Output, Your Rights

The first case of its kind before the Court of Justice of the European Union was referred by a **Hungarian court** — and there is still no ruling. Germany's federal supreme court heard the training-data case in September and signalled that it may send the question to Luxembourg too. What has been decided: a Munich judgment holds that copyright is infringed even when the training happened in the United States.

Deepfake Fraud: Verify Before You Pay

Deepfake Fraud: Verify Before You Pay

In the 25.6-million-dollar Hong Kong case it was not the video call that started the fraud but a phishing message — the deepfake was only there to remove the doubt. And according to the latest UK figures, losses to CEO fraud fell **53%** in 2025, to a record low. Prevention works. But the rule must not be tied to an amount.

Prompt Injection and Data Leaks, Seen from the Business Side

Prompt Injection and Data Leaks, Seen from the Business Side

In Google DeepMind's own measurement, the same model showed an 18% attack success rate on the standard test and **94.6%** when the attacker knew what the defence was. There is no complete solution — the researchers say so themselves. What there is: a handful of architectural decisions a ten-person company can also make.

The One-Page AI Policy: A Template You Can Fill In

Krisztian Eyssen, Krisztian Eyssen

The One-Page AI Policy: A Template You Can Fill In

The strongest argument for having a policy is not security, it is **Directive (EU) 2016/943**: under EU trade secret law, protection only exists if the holder has taken reasonable steps to keep the information secret. With no written rule, a court can legitimately ask whether your pricing was ever a trade secret at all. Here is the eight-point template.

Shadow AI: The Tools Your Team Already Uses

Shadow AI: The Tools Your Team Already Uses

In a 48,340-person survey spanning 47 countries, **6%** of employees work under a policy that bans generative AI — while 41% have **no rule at all**, and 19% do not know whether one exists. The "everyone bans it, they use it anyway" story is false. The real problem is a different one, and you can map it in a single day.

GDPR and AI: What Can You Feed a Chatbot?

GDPR and AI: What Can You Feed a Chatbot?

The European Data Protection Board has said it plainly: a model is not automatically anonymous just because it is a model. And two national regulators, the Hungarian and the Spanish, have **not a single** published decision about an AI chatbot between them — so when someone says "our regulator has ruled on this", ask them where. What does exist: seven questions to work through in order, before you type anything in.

The EU AI Act: What Applies to You Today

The EU AI Act: What Applies to You Today

It entered general application six weeks ago, and it was rewritten in the meantime: the high-risk rules slipped to December 2027, the transparency duties did **not**. Two new prohibitions arrive in December. And the fact most people get wrong: the market surveillance authority is not the data protection authority.

AI Literacy for Your Team: A Practical Training Plan

AI Literacy for Your Team: A Practical Training Plan

Since August 2026 it has been a supervised and enforceable EU obligation that your company does something for AI literacy — but the wording of the law was softened in July 2026, and it does not ask that your colleagues know something. It asks that you made the effort. Four sessions, homework, and one measurable outcome that is not a knowledge test.
