My Story

Not a consultant who read about Thailand. I lived it.

I arrived in Thailand in 1983. Before Google. Before smartphones. Before anyone had a roadmap. I built businesses, made mistakes, lost money, learned lessons — and eventually built something that works. For 42 years I have lived what most consultants only theorize about.

Today I work with German-speaking entrepreneurs and investors who want to do business in Thailand the right way — without the costly detours I had to take myself.

Where I Come From

I came to Thailand at 7 years old with my father. I watched him build something from nothing — and I watched him lose it. That experience stayed with me. I spent the next 42 years learning how Thailand really works — not from books, but from within.

The Journey

42 years. One chapter at a time.

1983

Arrived at 7 with My Father

I came to Thailand at 7 years old with my father. Bangkok became home before I could fully understand why. That early life shaped everything — my language, my instincts, my deep understanding of how this country really works.

1990s

Building Businesses — and Making Mistakes

I built companies, lost money on deals that looked good on paper, navigated Thai bureaucracy without a guide, and learned hard lessons about partnerships, property, and legal structures. Everything I teach today, I learned the expensive way.

2000s

Mastering Three Worlds

After 20 years in Thailand I became fluent — not just in Thai language, but in Thai culture, Thai business logic, and the invisible rules that no textbook explains. German-speaking investors started finding me. The consulting work grew naturally from trust.

Today

200,000+ Community. One Mission.

Through Thai by Heart I built a community of 200,000+ people passionate about Thailand. Through Marco Sager Consulting I protect German-speaking investors and entrepreneurs from the mistakes I made. Same passion. Two channels.

Real Results

Stories from past clients

Investment Protection

€400,000 Saved Before It Was Lost

A German investor came to me days before signing a land purchase agreement. The contract looked clean. But the land title was a Nor Sor 3 — not a Chanote. Foreigners cannot own it under any structure. I stopped the deal. We restructured. He invested safely six months later.

Outcome Investment protected · Legal structure established
Company Setup

From 3 Failed Attempts to Open in 6 Weeks

An Austrian entrepreneur had tried twice with Bangkok law firms and once with a 'business setup' agency. All three failed at the BOI registration stage. In 6 weeks I connected him with the right licensed lawyer, the right accountant, and the right Thai director. Company open. Bank account active.

Outcome Fully registered Thai company · BOI approved · Operating
Expat Relocation

Family of 4 Relocated Without a Single Crisis

A Swiss family — two adults, two school-age children — wanted to move to Chiang Mai. They had read every expat forum and were overwhelmed. I built them a step-by-step relocation plan: visa strategy, school selection, neighbourhood shortlist, rental negotiation, bank setup. They arrived calm.

Outcome Smooth relocation · School enrolled · Living in Chiang Mai
Due Diligence

Fraudulent Partner Caught Before the Contract Was Signed

A German entrepreneur flew to Bangkok with a joint venture agreement ready to sign. His Thai partner had strong references and a polished presentation. Within 48 hours of my background check, I found two previous companies dissolved under debt and a civil fraud case. The deal was cancelled.

Outcome Fraud prevented · Capital protected · New partner found
Hospitality

Restaurant Concept Sold Before the Losses Mounted

An Austrian couple had run a restaurant in Phuket for 18 months with steadily declining margins. They could not see a way out without losing everything. I assessed the lease, the brand value, and the local buyer market. We found a Thai buyer within 3 months and structured an exit that recovered their initial investment.

Outcome Clean exit · Investment recovered · No legal disputes
Visa & Residency

Digital Nomad to Legal Resident in 90 Days

A Swiss software consultant had been doing 30-day border runs for two years. Every trip was a risk — Thai immigration was tightening. I built him a compliant long-term residency structure using the Elite Visa combined with a registered consulting entity. Border runs ended permanently.

Outcome Elite Visa secured · Legal entity registered · Fully compliant
