About Us

Who we are

Today we live in a real-time marketplace of communities where individuals are happy to engage with other people, brands and organizations through connections, conversations and information sharing – but only if those entities offer substantial value and relevance in exchange for their time and attention.

We are passionate about the science and art of listening to and engaging with people. With insight, with understanding and with a response that is helpful and valuable. We help our companies, brands and organisations move from campaigns to narrative, from intrusion to engagement and from consumers to communities.

Our History Our Awards

About Us

Our History

MSLGROUP’s Warsaw branch was built on  the agency Ciszewski PR.

Our history dates back to 1994, when sports journalist Jerzy Ciszewski established Poland’s first public relations agency. Ciszewski PR’s first large assignment consisted of providing comprehensive PR services for the Camel Trophy rally in Poland.

The years 2006-2010 mark a period of the company’s dynamic growth and specialization in consumer, corporate, financial, sports, pharmaceutical and digital communications.

Our campaigns “24th of June – Poland’s Free Hug Day”, “Trust Tap Water”, “Hoop Caroling” and “Send your CV. Someone’s waiting” were awarded with the industry’s most prestigious prizes.

In 2011, Ciszewski PR’s shares were purchased by MSLGROUP, an agency belonging to France’s Publicis Group. This resulted in gaining access to the world’s best know-how in the areas of brand and company communications as well as in community engagement. 

MSLGROUP was established in 2009 after Publicis Groupe announced that it would be bringing its PR and events agencies together to form a singular, global network. In the years to come, the network grew. Today, MSLGROUP accounts for over 100 agencies in 26 countries worldwide, forming the 5th largest PR agency in the world.

What we do

Our approach

Consumers are changing their approach towards brands. Brands are chosen through a process similar to that of choosing one’s friends – both sides must match. Consumers expect companies to have modern values; values which do not lie in the regions of basic business practices. Accordingly, brands have become increasingly eager to engage in topics which truly change and improve the everyday life of their consumers.

We’ve come to learn that in such times, campaign ideas should stem from a deep knowledge of a customers needs and preferences, and not from generalized market research. Since there is no singular way of creating a brand’s story, we put various methods, tools and communications channels to use to give each story its own unique character.
