About Company

Everyone knows everything about finances - we know them best. For many years, we have created and designed IT systems for banks, insurance companies and brokerage companies. We were at the birth of more than one financial institution, but sadly - fortunately rarely - we were also present on their more or less violent descent from the financial world. We know, therefore, how financial institutions can earn money, but also how to protect them from losing this. Until now, we were providing financiers with a gold-digging shovel for digging and searching for nuggets. Today, we want to try our luck and combine IT and finance. ONE account, because that's how we've called our project, will start production in the coming months. We want to involve friendly societies, not just these dealing with banking and finance. All this to create a truly multi-genre project. Details of our solution will be presented soon.
