42 years. One chapter at a time.
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.
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.
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.
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.
