About Thomas Zagler

Many companies grow successfully in their early years because the founder is closely involved in everything.

Decisions happen quickly. Communication is direct. Everyone knows what matters.

But as organizations expand, the same strengths that enabled early success often begin to create friction.

More people become involved in decisions. Responsibilities overlap. Managers hesitate to act without confirmation. Eventually more and more issues return to the founder.

Not because the team lacks capability, but because the structure of the organization has not yet adapted to the company’s new scale.

Today
Founder Advisor
Working with founders navigating the transition from entrepreneurial growth to organizations that no longer depend on them for every decision.

My own career has unfolded almost entirely inside growing organizations.

Over the past three decades I have built and led companies across Europe and Asia, often in environments where teams, markets, and cultures had to be aligned under demanding conditions.

I began my professional life in engineering and technical sales in Austria before moving to Vietnam in the 1990s to work in international sourcing and manufacturing.

From there I founded and co-built several international businesses, including manufacturing and distribution operations supplying markets across Europe, Australia, and North America.

Later I moved into larger operational leadership roles, eventually serving as CEO of organizations employing more than a thousand people across multiple countries.

Across these different roles, one pattern appeared again and again: growing companies rarely struggle because of strategy. They struggle because complexity outgrows structure.

What I Focus On

My work today centers on helping founders address that transition — not through abstract leadership theory, but through practical operating structures that allow organizations to function effectively as they grow.

  • Clarifying decision ownership
  • Defining role accountability as teams expand
  • Establishing effective operating rhythms for leadership teams
  • Designing communication structures that reduce noise
  • Preserving the company’s culture while complexity increases

The objective is simple: build organizations that continue to scale without pulling the founder back into every decision.

Location

I am based in Ho Chi Minh City, Vietnam and have spent most of my professional life working across Asia and Europe.

Today my work focuses primarily on founders navigating the transition from early entrepreneurial success to the demands of running a larger organization.
