Marketing agency
Let’s keep it short: you don’t want an agency that only does “posts”. You want market dominance. In a world where attention is the hardest currency, we deliver the strategy for real growth. We’ve been scaling brands for over 10 years – from the first social ad to nationwide TV campaigns and point of sale. Why coordinate different agencies when One masters the entire ecosystem of performance, e-commerce and brand awareness?
One #1 Cross-Media Dominance: Social, Ads & OOH
Real brands are everywhere. We combine the viral power of TikTok, Instagram and YouTube with the massive reach of TV commercials, streaming ads and outdoor advertising (OOH). We also set standards on site as a trade fair agency for the perfect brand presence. Whoever knows how to turn 1 euro of investment into 5 or 10 euros of sales wins. We develop campaigns that work across all media and reach your target group at every touchpoint.
One #2 Content Creation: UGC & Viral-Concepts
Traditional advertising is clicked away – authentic content is consumed. We produce user-generated content (UGC) and high-end assets that are psychologically trimmed for performance. Whether for social media ads or as hybrid UGC spots on TV: we create content that builds trust, tells the brand story and directly promotes sales in the store.
One #3 Performance marketing at sales level
Reach is good, ROI is better. Our performance marketing goes far beyond simple ad management. We dominate Google Ads, Google Display Ads and Amazon Ads to convert purchase intent directly into sales. Through high-converting sales funnels, smart newsletter marketing and automated email marketing, we retain customers for the long term. We also deliver results for your team growth: With targeted social recruiting, we find the right employees for your scaling.
