In the year 2000, Dr. Dr. Rainer Zitelmann founded the Dr. ZitelmannPB. GmbH. Prior to this, Dr. Dr. Zitelmann was a property journalist for the daily newspaper “Die Welt”. Holger Friedrichs joined the company in 2001 and helped to create and expand its PR sector. From the very beginning, the company has seen itself as a consulting agency for the positioning and communication of real estate companies. Initially, the company solely focused on traditional areas of PR and corporate publishing, but along with an ever-changing media landscape, online positioning and investor relations soon followed. The “ImmoNews der Woche”, a weekly newsletter, has been a very important channel since day one, and remains an integral part of the PB3C GmbH, reaching a four-figure audience.

In January 2016, Holger Friedrichs bought the company. The company celebrated another milestone just over a year later, in March 2017, when Dr. Josef Girshovich, who also developed PB3C’s political communication sector, was made its first associate. The business consulting agency changed its name on March 20, 2017 to PB3C.
