CORK, IRELAND (28 April 2025) — IPREX, the top global network of independently owned communications and public relations (PR) agencies, has welcomed three new partners to its growing international network. The additions deepen IPREX’s presence in Europe and expand its reach across Latin America. 

The new agencies are: 

• Thomas Marko & Associés, a strategic communications and influence consultancy based in Paris, France 
• TDUB Kommunikationsberatung, a leading communications consultancy, specializing in strategy, PR and Influencer Marketing, based in Germany’s media capital, Hamburg. 
•  Square Root Marketing, a multi-country agency that blends strategy and storytelling to elevate brands across Latin America, specializing in public relations, field marketing, and thought leadership.

“France and Germany are key markets for IPREX,” Ann-Marie O’Sullivan, IPREX Global President and CEO & Founder of AM O’Sullivan PR said. “These new partners strengthen our ability to collaborate across borders and build integrated campaigns with in-market insight. And with Square Root Marketing, we’re growing our reach across Latin America with a team that already understands how to operate across geographies.” 

“Welcoming partners of this calibre reflects our commitment to building a network of trusted, independent agencies that understand influence at both the local and global level,” O’Sullivan said. 

All three agencies will be formally introduced at the upcoming IPREX Annual Global conference in Miami (14-16 May), where they will participate in sessions on business development, global growth strategy, and cross-market collaboration.
