2026-07-12Not official

Foreign-owned launch planning usually fails when teams compare entity forms before they clarify the real activity, ownership profile and regulator path.

What to review together

  • the real TSIC activity rather than a broad marketing label;
  • Foreign Business Act exposure and whether BOI changes the route;
  • company form, tax setup and staffing cost after incorporation.

Practical use
