Klaus Barkhausen
Founder & Principal Architect · 25+ years building enterprise systems
Klaus Barkhausen has spent 25+ years designing enterprise systems for large, regulated, multi-country organizations, including Richemont and its Cartier brand, as well as Anthology. He founded 5 Stars Technology to find the processes that make organizations slow, costly or hard to audit, study them in depth, and rebuild them into operations that are efficient, cost-effective and auditable.
What Klaus brings
The architect who builds what he scopes
Disciplined discovery
Interviews, shadowing and process mapping until the real process — not the documented one — is on the table.
Applied AI
Document intelligence, classification, extraction and retrieval on Azure and AWS, used where it earns its place.
Governance by design
Human review, enforced approvals, role-based access and audit trails from the first pilot, not bolted on later.

Credentials
Cloud and AI credentials
Klaus designs, builds and runs solutions across AWS, Microsoft Azure and Google Cloud, so recommendations follow your environment, not a vendor preference. He holds AI certifications across AWS, Microsoft Azure and Google.
“In every one of those organizations, the hard part was never the technology. It was understanding how the work actually happened, who was accountable, and where control was being lost.”
