Yass’ challenges

April 2025: YASS enters the French soda market, one of the most competitive there is. The brand has no time to settle in gently; it has to quickly establish itself as a credible alternative.

Its main playground is TikTok, where its core audience is: Gen Z.

The challenge is twofold: build awareness of a fun, colorful and cheeky brand world, and explain a category still unknown to the general public, prebiotic sodas. With a very concrete end goal: create desirability, trigger adoption and accelerate sales.

Our solution

Our idea: flood TikTok with a three-step launch.

A teaser to build intrigue
An explosive reveal to maximize impact
An ongoing presence to establish the brand for the long term

To sustain it over time, the messaging relies on four editorial pillars: educating without guilt-tripping, lifestyle, “famous” content to make the brand iconic and “stand-out” content to promote points of sale.

Creators are at the heart of the setup, with crash test formats published from their accounts and then amplified as Spark Ads. Outcome: more than 38 million views, 40 creators activated and more than one million cans sold.

Our methodology

🧑‍💻

Our Social Media agency offers a complete methodology to help you reach your goals

Strategy

Before producing a single video, we defined the launch’s editorial strategy: a teaser, a reveal, then an ongoing presence built to last. The four content pillars (education, lifestyle, famous, stand-out) give each video a specific role and ensure consistent messaging on TikTok, week after week.

Casting

We selected TikTok creators in line with YASS’s image and values: spontaneous, funny, able to carry a cheeky tone without forcing it. Forty creators were activated, with complementary profiles to cover each editorial pillar and speak to Gen Z in its own language.

Production

The videos were produced with our content creators, drawing on the brand assets provided by YASS. The crash test format became the backbone of the setup: it shows the product, gets people reacting and explains the prebiotic soda category without ever slipping into an advertising pitch.

Sponsoring

Content published from the creators’ accounts was amplified as Spark Ads. This choice preserves the authenticity of the messaging while extending its reach well beyond the existing communities. Paid promotion supported each key moment of the launch to establish the brand and grow its community.
