AGENCY FOR GUERRILLA MARKETING.

Guerrilla Marketing is all about making a big impact with bold, unexpected ideas. Instead of relying on standard ad placements, it uses surprising formats, unconventional locations, and creative storytelling to capture attention and connect with people in the real world.

We love unconventional. That’s why we partner with brands to develop standout guerrilla campaigns that cut through the noise. Whether it’s custom-made installations, reverse graffitis, stickers, floor graphics, or guerrilla marketing posters — we create concepts that resonate with every target group.

Run a guerrilla campaign – and we’re in. Our guerrilla marketing agency offers a flexible portfolio: from fast, ready-to-launch activations to complex, tailor-made campaigns. We work with a wide range of tools — from outdoor advertising and street art to floor stickers, flash mobs, events, and street branding. Whether classic guerrilla posters or bold one-off ideas, we turn creativity into visibility.
