Heureka Group: One sound logo for nine countries

Heureka Group, the largest shopping advisor in Central and Eastern Europe, needed a memorable audio signature that would work in nine countries. Online shopping is full of endless scrolling, choice paralysis, and distrust of unknown e-shops. Heureka wanted a sound that turns all that into instant relief: an audio exclamation mark that makes people feel "Got it!" or "This is the one!"

They needed a sound that would

  • Carry the same emotion across nine countries, cultures, and brand names (it isn't called Heureka everywhere).

  • Melt shopping stress into a small personal victory.

  • Be short, punchy, and memorable in the click-and-pay era.

  • Sound great on phone speakers as well as in TV ads.

  • Reflect both the tech and human sides of the brand, with room to grow.

  • Pair naturally with the brand's strongest asset: the exclamation mark.

Our approach

Instead of predictable fanfares, a shouted "Heureka!", or generic magic sparkles, we built the sound logo like a UI sound that confirms the best possible decision. We rooted the "Aha!" moment in the small everyday victories that happen offline, too.

As an organic base, we sampled two household sounds that signal anticipation and a happy ending: the click of a kitchen timer and the pop of a toaster. The logo opens with a light, slightly chaotic texture, like browsing a million options, then quickly clears into a rising, stable melody. Its shape mirrors the exclamation mark itself: a longer dynamic line finished with a clear, triumphant dot.

The result

A warm, human, and friendly sound logo that travels easily across borders and services. It takes the edge off shopping anxiety and works like a reassuring double-check people look forward to hearing every time they make a good choice.

This is how it sounds

Melodic sound logo

A warm melody that turns doubt into the bright tone of a good decision.

Rhythmic sound logo

A quick, crisp signature that clears shopping doubts like a snap of the fingers.

That's what the client says

For Heureka Group, we needed to create a memorable logo that would work well across nine countries and seven different brands. The team at Trebledu handled this challenge brilliantly. I particularly appreciated that, before any work began in the sound studio, we held several in-depth discussions to ensure everyone had a clear understanding of the brand's true essence and what it represents for our customers. Thanks to this thorough preparation, the creative process itself was carried out very quickly and efficiently.
