About ERTHAK

ERTHAK is a limited liability company specializing in corporate governance, with a particular focus on family-owned businesses to support their continuity and improve decision-making effectiveness.

We also work with private-sector companies, institutions and mission-led entities, and individual leaders when more clarity, structure, or capability is needed.

We use research-informed tools and practitioner experience to understand the context, design solutions with the client, support implementation, and help embed agreed practices.

• Integrity
• Respecting the client's legacy
• Creativity
• Excellence
• Social contribution

• Proactive accountability
• Objective assessment
• Continuous improvement
• Fairness
• Safeguarding information confidentiality

Research can help explain what is happening. Practice determines what can work in a specific organization. ERTHAK brings both into the same engagement through structured diagnosis, clear design, supported implementation, and regular review.

Welcome to ERTHAK.

Every organization carries a history of decisions, relationships, and values. As it grows or changes, those strengths can become harder to manage when responsibilities shift, structures fall behind, or leaders face new expectations.

ERTHAK was established to help organizations and leaders discuss difficult questions, make responsibilities clearer, and build practices that can carry their work forward. We bring special understanding of family enterprises together with disciplines that apply across business and institutional settings.

Our role is to bring structure and an independent perspective while respecting the character and context of every client.

We look forward to listening to your story and working with you on the next chapter.
