felix_baron · reddit · 2026-09-21

A developer exploring the EU LLM app market opened a discussion on what actually blocks shipping a paid service, offering a five-part checklist to stress-test: GDPR/AI Act data handling (assess by intended use, not blanket high-risk), traceability without archiving every span, abuse and prompt-injection defenses combined with server-side price validation, tenant isolation and spending caps, accountability when agents touch ERP/CRM systems, and post-launch quality evaluation (distinguishing retrieval vs generation vs tool failures, cost per useful result). He's collecting one concrete blocker from teams that have shipped LLM apps to EU customers.
