Some may think it is expensive to establish a business in the United States or Denmark. On the contrary, it is not. We have made the process simple and inexpensive. We deliver an all-round solution by taking care of the legal as well as the administrative challenges. In the United States and Denmark, it is essential that all legal requirements are fulfilled upon formation of your business. You can rest assured that we make sure of that.

About us

We assist a wide range of Danish businesses in the U.S. We have made it easy and inexpensive to start a business in the U.S. and in Denmark.

Save Time and Costs!

Because we assist with both U.S. and Danish law at the same time, we provide legal solutions that are linked and consistent on both sides of the Atlantic - in contrast to several counselors' partial solutions that are often uncoordinated and inconsistent. This is faster and often results in significant savings for our clients. We also understand the importance of utilizing modern technology in our business and to be directly available to you.

Offices in the U.S. and Denmark

We have offices in New York and Copenhagen and are therefore available to you almost the entire day. Our presence in the United States and Denmark gives us a true and direct insight into the conditions and challenges that our clients' face in the U.S. and Denmark. Our international presence is the foundation of our unique international experience and expertise, of course, particularly regarding the "black letter law," but also with respect to business culture, negotiation techniques and language barriers.
