The tax layer for cross-border capital.

Cross-border wealth is growing faster than advisory capacity can cover. Manual work at the top of the market is slow and expensive. TaxSailor computes routes on a versioned treaty graph and cites the source on every hop.

The thesis

Three markets are colliding - and no one has the graph.

Cross-border wealth is transferring

In Germany alone, about €400 billion in wealth is transferred each year, with that figure expected to rise. When assets cross borders, treaty and inheritance rules compound.

Advisory is capacity-constrained

Boutique firms cannot staff every cross-border matter. Language-model tools guess at treaty edges. The graph has to be compiled, not prompted.

The graph exists - nobody's built it

Bilateral treaties, protocols, and domestic rules are a graph problem. Live routing coverage: the live treaty graph.
