I was sad to read that the cloud storage provider CloudSafe is closing down end of October. I liked the idea of privacy and security first approach Cloudsafe took. Secondly, the storage was hosted in Germany where I at least assume that privacy is still of a higher importance compared to other countries.
The founder wrote an email to customers today arguing that they were not able to convince enough users to opt for the paid tier. Most users would still value price per GB more than implemented security features so that scaling decides about the success of a platform. Obviously the dominating big players in this area such as Google, Dropbox, Amazon and perhaps soon Apple (all US) are in a much better position to pull this off.
I personally wish the team all the best and hope they will be able to make use of their ideas in other areas.
