Citadello

Citadello is a stealth startup. SS - is a type of company that operates in quiet and silence to outsiders, avoiding public attention. This may be done to hide information from competitors, or as part of a marketing strategy to manage public image and generate expectations and interest from potential clients.

The phenomenon is well known in the venture capital (VC) community. Since investors may have to disclose funding a stealth startup, their names are made public, but often only a general summary description is known about the company.
