Jack is the teammate you hire. Banker Jack OÜ is the company that built him — founded in Tallinn, operating from the most digital country in the EU, and built on a simple conviction: there will be far more entrepreneurs than traditional accounting firms can serve, and someone has to do the work.
Founder & CEO. A licensed financial-institution operator who built the Banker Jack platform, with deep roots in Estonia's e-residency and startup ecosystem. Mihkel personally onboards every early client — when you meet Jack, you meet him too.
Around the company: senior operators in risk (Jaak Erm — ex-Paywerk, acquired by Swedbank) and legal & compliance (Hiie Ormisson — IPF Digital), and advisors from Estonia's fintech ecosystem.
Banker Jack was started in 2025, five hundred years on from Jakob Fugger, to pick up his craft.
Fugger financed emperors and popes from a counting house in Augsburg, and he is remembered for the money. He is worth remembering for the method. He brought double-entry bookkeeping north into Germany and ran consolidated accounts across more than eighty branches, at a time when most merchants could not have told you whether they were solvent. His own grandfather had walked into that city a village weaver; three generations later the family was banking the Holy Roman Empire. Wealth like that is not a windfall. It is bookkeeping, held to for a very long time.
The almshouse Fugger endowed in 1521 still houses people in Augsburg, at a rent he fixed at under a euro a year — five centuries of proof that a well-built system outlasts the hands that built it, and can be taken up again by new ones. For most of those centuries this craft stayed where he left it: with institutions large enough to keep a finance department. Jack's work is to carry it the rest of the way — to a business of one.
Estonia is the natural birthplace for an AI CFO: fully digital incorporation, digital tax filing, and 130,000+ e-residents running EU companies from 170+ countries. Banker Jack serves them from day one — and we are building for what comes next: EU-Inc, the proposed pan-European company framework. We publicly champion the movement, and Jack is being built as the compliance engine that can serve a single EU-wide entity type the day it exists.
Clients, accountants, builders, press — one address reaches the people who build Jack.
