OXS16 in Frankfurt, where partnerships matter

24 Sep, 2016

The European OX Summit will be hosted in Frankfurt on October 13 and 14. For a couple of days the city will be the capital of the open-Cloud community, and Summa could not miss this chance. We will exhibit at the OXS16 for the third year in a row.

Summa has been a solid partner of Open-Xchange for the past three years. Gathering at their yearly European Summit is not only a tradition, but a commitment. The event traditionally stresses the importance of partnerships in the Open-Xchange ecosystem, which connects the key decision-makers in the hosting, telecommunications, cable and mobile carrier industry. It is the chance for ISVs and service providers to showcase their portfolio and solutions, and share and exchange knowledge with all delegates. Set directly on the banks of the River Main, and within easy walking distance to the train station, the futuristic Westhafen Pier 1 is the perfect venue for the open exchange of ideas. Check out the OXS16 agenda and register at the link. Contact us at go@summa.io if you wish to make an appointment at our stand, we are looking forward to welcoming you.
