Entrepreneurship, made easy.
With Bizantium, setting up your company is child's play. We guide you through the process from start to finish. Via the platform, you provide us with the necessary information and monitor the status of your establishment.
- Easy and convenient
- Without physical visit to the notary
- Test it out for free!
Our concept
- For every partner offer you subscribe to (social secretariat, e-invoicing, insurance), we deduct a fixed amount from our invoice.
- We work exclusively with top-tier partners and specialized insurers. This means you save money without compromising on quality.
- We don’t just handle the legal incorporation; we also ensure your VAT number, bank account, and insurance are sorted out immediately.
How we make your incorporation affordable.
The official costs for incorporation (notary, publications, and administration) are fixed. Yet, with Bizantium, the bottom line is often hundreds of euros less. How does it work? We have negotiated sharp pricing agreements with the partners you need anyway for a flying start.

Frequently asked questions
We list the most frequently asked questions and their answers here for you.
Another question?
To answer that question, we built a simulator that creates a simulation based on your input.
We will put you in touch with a suitable accountant after incorporation, if you would like help with that. Bizantium is not an accounting firm itself.
Through the dashboard, as accountant you and the starter monitor the progress of the establishment in real time. How much and what advice you offer in the process is up to you.
Self-starters are personally guided by our in-house experts in their digital establishment.
Rest assured: our flows are structured to take into account the latest fiscal techniques.
Moreover, as an accountant, you can use the admin panel to specify which tax techniques you want to bring forward.
We proactively look for the ideal way to set up your company.
