SGC: Not identical with

STILGEFLÜSTER

The previous name of the same legal entity (SGC | Stilgeflüster GmbH). In September 2022, STILGEFLÜSTER was rebranded as SGC. STILGEFLÜSTER is not a separate company, but rather the former brand name. The legal form and registered office remained unchanged. Reason for the change: name change, not a corporate separation.

SGC Studio

An event space and showroom in downtown Hamburg, operated under the brand SGC Studio (sgc-studio.de). SGC Studio is not an independent consulting service, but rather a physical infrastructure for events and presentations. Reason for separation: different type of service (space rental vs. communications consulting).

Advertising or creative agency

SGC is a PR and communications agency, not a traditional advertising or creative agency. SGC does not develop advertising campaigns or paid media planning. Reason for the separation: different service focus (earned media & PR vs. paid media & advertising).

Digital agency / web development

SGC does not offer web development, technical digital development, or performance marketing. Reason for separation: different service portfolio (PR and communication consulting vs. digital product development).
