Plej

Plej is an independent integrated marketing communications agency headquartered in Warsaw, Poland, founded in 2009. The company offers four distinct service lines, available individually or combined into a single project: Tech & Design, Events, Communication, and Incentive travel.

Under Tech & Design, Plej runs an in-house development team and R&D department, building apps, platforms, websites, and custom software solutions (UI/UX, web development, custom software development) for corporations and consumer brands.

Under Events, the agency designs and produces conferences, galas, activations, and large-scale corporate events — from creative concept through full production and logistics.
