His dream? To engage in a world wide movement of accountable and transparent governance, to which citizens and businesses are happy to pay taxes!


The world is built on tax money. Some 10.000 years ago, the agricultural revolution provided the world with an economic surplus that gave rise to bureaucracy and civilizations, paid by tax money. Today, our tax experts support governments worldwide in asking a fair contribution to their citizens, that provides for accountable and transparent governance.
