The AG and the GmbH / UG have some similarities, but are characterized by even more differences. In both cases, the companies are legal entities that have their own legal personality and where the company is represented by executive bodies. Both forms of enterprise are corporations. The most important and biggest difference is the amount of share capital required. In the case of the GmbH, you need to hold 25,000 euros in share capital, while as an AG you need to prove that you have double the financial outlay of 50,000 euros in share capital. With the UG, even a single euro is sufficient for the foundation.  One of the most important differences is that a shelf corporation must have at least three governing bodies: Management Board, Supervisory Board and General Meeting. The management board manages the shelf corporation on its own responsibility (§ Section 76 AktG) and, in contrast to a GmbH / UG, is not bound by instructions.
