Case Study: Zelmer achieves stronger customer relationships with Brand24

How Zelmer Uses Brand24 to Build Relationships with Fans

Zelmer, a long-standing Central European vacuum cleaner manufacturer, wanted to strengthen relationships with customers by spotting and responding to authentic fan moments on social media. Their challenge was monitoring brand mentions in real time and turning organic conversations into memorable, brand-building interactions.

Using Brand24 for social listening, Zelmer found a 4-year-old fan whose birthday cake resembled a Zelmer vacuum, invited the family for a factory tour, created shareable content and surprised other loyal customers — then launched a customer-story contest. The initiative generated strong engagement (the Wojtek video reached ~40k views, 250+ likes and 27 shares) and overwhelmingly positive comments, boosting brand sentiment and awareness.
