Sentry
Error tracking + performance monitoring for production. Source maps, release tracking, alert routing
Four phases, clear handover.
Discovery
Sketch it together: processes, data, risks. Clear go or no-go.
Prototype
Functional version on synthetic data. Your production system stays untouched.
Validation
Feedback loops and integration into your system. Honest performance numbers.
Handover
Code, docs, live training. Your team carries on.
Demonstrated practice, not promises.

What managing directors need to know now.
Minimal
Text assistance, research, spam filters - no special obligations
Limited
Customer-facing chatbots - transparency obligation (Art. 50)
Forbidden
Social scoring, biometric mass surveillance - banned since 02 Feb 2025
From Aug 2026, transparency obligations apply to all customer-facing AI systems (Art. 50 EU AI Act).
High-risk AI (HR, credit, legal advice, etc.) requires documentation, audits, and human oversight.
SMEs up to 750 employees get simplified rules, but no exemption from transparency obligations.
Not legal advice. As of 2026-06. Deadlines subject to legislative amendments.

Learn the method I build with.
At agenticbuilders.at I walk you from first idea to a finished app. Not the pretty demo that falls apart the moment you publish it, but an app that runs reliably. A method, not a recipe. One that still holds up when the tools have different names next year.
How to check it really runs · stay secure · keep costs under control · go live. The unglamorous 80 percent nobody else shows you.
