AgentTrail started in 2026 when we realized the EU AI Act deadline was approaching and mid-market companies had no affordable way to comply with Article 12's audit trail requirements. Existing solutions cost $50K+/year — out of reach for companies with 50-500 employees. We built AgentTrail as an open-source SDK: cryptographic hash chains with zero data retention, verifying offline. No vendor lock-in. MIT licensed. Now backed by European CTOs and compliance leaders who confirmed the problem is real.
