Our Foundation

Decades of Expertise.
Built by Humans, Backed by Integrity.

Our tools are the product of over 30 years of specialized experience in international taxation — navigating the complexities of PFIC rules, cross-border reporting, and IRS compliance long before these subjects entered the mainstream. Paired with more than 30 years of software development expertise, every calculator, assistant, and preparation tool we offer has been meticulously engineered to be accurate, reliable, and built to the exacting standards that international tax demands.

We believe the professionals and families who rely on us deserve complete transparency: while we leverage AI as a productivity tool to accelerate certain workflows, every line of code, every calculation, and every piece of logic at the heart of our products was written, designed, and validated by our own experts. We do not rely on AI to create, reason through, or verify the technical and legal foundations of what we build — that responsibility rests entirely with our team, backed by over 30 years of hard-won expertise.
