Company / Finland
TrustCore AI Systems Oy.
Engineering the right to act.
A Finnish AI infrastructure company developing runtime governance, controlled execution and evidence before consequence.
Our focus
The transition from
recommendation to action.
As AI systems gain access to tools and workflows, they need more than good instructions. They need explicit authority, bounded scope and a meaningful opportunity to refuse before an external effect.
TrustCore develops control patterns and technical infrastructure for that boundary. The focus is practical: evaluate a narrow workflow, make decisions inspectable and connect claims to evidence.
Our working principles are identity-bound authorization, policy-bound routing, fail-closed enforcement and human final gates for high-consequence actions.

Founder
Kari “Gary” Hyötylä
Founder & AI Architect
A hands-on systems builder working across hardware, software and AI. TrustCore grows out of a practical question: how do we keep authority and control explicit as systems become more capable?
Gary is also the author of Governance Before Decision, a field guide exploring proof, permission and human-controlled AI execution.
