Every marketer is obsessed with giving answers, crafting neat slogans that resolve problems. But what if the secret to a record-breaking campaign is doing the exact opposite—asking questions that cannot be easily answered?
Ukrainian dairy leader Galychyna, alongside creative agency Bickerstaff.734, decided to start testing psychological hypothesises. They filled nine Ukrainian cities with more than 100 hyper-local, existential, and borderline bizarre billboards, leveraging the Zeigarnik Effect—the cognitive phenomenon where the human brain remembers open questions far better than resolved ones. By refusing to give immediate answers, the brand created cognitive tension, forcing passersby to actively think and debate.
To make it work, the team spent weeks “walking” through streets via Google Maps, studying local architecture and neighborhood inside jokes to tailor each billboard to its exact location. The strategy paid off instantly on social media, completely blowing up on Threads. People began hunting for the billboards like Pokémon, turning quirky street prompts like “Is it okay to name your son Bill Board?” into a country-wide meme marathon filled with organic discussions and user-generated content.
This psychological tension and digital buzz converted directly into hard commercial data:
- +42% Efficiency Boost: The campaign performed 42% more effectively than planned per every dollar spent.
- 80% Market Reach: The ads reached 33% more people than projected, capturing nearly 80% of all yogurt buyers in the country in just 30 days.
- 6.7% Engagement Rate: Driven by the viral waves on Threads, the engagement rate was several times higher than the industry average.
- +82% Sales Surge: Sales of Galychyna’s flagship “Karpatskyi” dessert line skyrocketed by 82% during the campaign month.
