From the very first call I received clear, detailed and precise explanations - exactly the technical depth I was looking for. Within just two weeks the company had established a fully operational LLC for me, handled all incorporation documents and completed almost every step of the process; we are now moving forward with opening a dedicated bank account for the LLC. What I liked most: • Total availability and dedication – At every stage I was guided by a dedicated expert who provided immediate, transparent answers and conveyed information in a professional, clear manner. • Outstanding informative response – I sent a list of complex questions and got back a long, well-crafted, personalized email that resolved 100 % of my concerns in one go. • Speed of execution – A process that many other providers drag out for months was wrapped up here in two weeks, with no delays or bureaucratic “surprises.” • Trust and security – I had tried other firms that felt unsafe and even risky; Flag Theory earned my confidence through professionalism and rigorous risk management. Result: I now have a valid LLC entity, a structured tax plan, and complete regulatory peace of mind - all without wasting time or wrestling with exhausting paperwork. Bottom line: If you need to form an international company, handle global tax planning, or open a Crypto-Friendly bank account, Flag Theory is the right choice. Save yourself the headaches - just let these professionals do the job! — Ori Y. ### ★★★★★ Great Experience - Il Ma · 2025-05-08 I had a great experience working with them to set up our companies internationally.
