Four tribes, living worlds apart, bound by the same instinct and way of life: to run. From the mountains of Mexico to the plains of Southern Africa, this film takes us on a journey through time and across continents to explore how running has shaped, and continues to shape, their lives.

But beyond their stories, it’s an invitation to reflect on our own need for movement, and the primal drive that keeps us moving forward.

As human beings, we’re constantly doubting in our everyday lives. Green or blue shirt for an important call? Italian or sushi for a first date? Clifford or Cooper for the puppy’s name? Life is already complicated enough... which is why idealo exists: to help people easily compare and find the best option among millions.

I developed the creative concept built around this insight, then wrote the scripts, selected and directed the French voice-over, and provided cultural guidance to make sure the campaign resonated naturally with the local market.

This is how I bank’ is a bold statement: a declaration of the freedom and confidence you get from banking with N26. It challenges an industry that’s increasingly out of sync with what people expect from their bank, and promises that better banking is just a few taps away.

For this campaign, I handled the full transcreation for the French and Spanish markets, developing new scripts and fresh lines while keeping the core message and tone consistent across regions. I also adapted the main tagline to ensure it felt natural, modern, and culturally spot-on in both markets.

At R/GA Berlin, we were tasked with launching Google’s video game service, Stadia, across three key European markets: France, Germany, and Spain. We set out to reimagine what it means to be a gamer: no console, no downloads, no updates. Just you, your screen, and instant access to top-tier games at the push of a button.

Beyond the core campaign idea, I re-wrote and adapted the scripts for the French market, ensuring the VO lip-sync matched naturally with the English master to keep everything seamless on screen. I also handled VO casting and direction. Beyond the hero films, I contributed to the creation of additional assets such as social content, banners, and OOH.

Plum automates your saving. The customer research showed that people know they could be saving better, and why that’s important, but just don’t get round to it. So instead of focusing on product, we spoke to the root causes of financial inertia, positioning Plum as the answer to procrastination and the fear of getting it wrong.

With this insight as a springboard, I crafted the new French lines, shaping the rhythm, rhymes, and punchlines to land smoothly and memorably for the audience. These adapted lines became the backbone of the OOH campaign in France.

To support the launch of the release of the final season of La Casa De Papel in France, Netflix launched a nationwide campaign to find the show's biggest fan. Amplify created a format-busting IRL-meets-content fully integrated phased campaign that mobilised Money Heist's devoted fan base, to find and reward the ultimate fans of the series in France and Poland.

With this campaign (online video, social media, microsite...) we wanted people across France to realise the incredible fandom that surrounds the show and the impact it's had on pop culture.

Using the US Slack's current creative concept: 'It wouldn't be email at all,' developed by R/GA San Francisco, we were asked to come up with new copies and add cultural elements that alluded to the mainstream corporate culture in each market (France, UK, and Germany). This allowed the new audiences to resonate with the concept in a much more accurate way.

Apart from online videos, the campaign included social media (IG, FB & LinkedIn), TVC, OOH, and banners.

There’s a new vodka on the market: a pure Polish original. But the harsh reality is simple: the shelves are already packed with vodka brands. And if you’re not a spirits lover, the benefits of our fantastic product won’t make you stop or even care.
Instead of ignoring this truth, the brand leans straight into it. No gimmicks, no glossy clichés, just radical honesty to highlight its purity and transparency.

Building on this positioning, I wrote all the scripts from scratch and developed additional copy for print and OOH. The tone was deliberately stripped-back, direct, and refreshingly honest staying true to a brand that embraces what others avoid, and says things exactly as they are: honest.

Using the French expression “mettre l’accent sur....” literally “to put the accent on something,” meaning to emphasize or highlight,we built a campaign around the idea that foreign accents make every trip feel more vibrant, alive, and fun. A perfect fit for an airline that invites you to discover new places, new people, new accents, and new experiences.

For the French market, I developed the full campaign concept in collaboration with Ogilvy Barcelona, bringing strong cultural insight to ensure the idea felt genuinely French, not simply translated. From linguistic nuance to local references and tone, my role involved deep cultural consultancy to shape a campaign that resonated naturally and playfully with a French audience.

Transcreation goes beyond translation: it's about capturing the cultural nuances of the target region and tailoring the message to resonate with a new audience, all while preserving the original brand's tone of voice.

Over the last years, I’ve had the opportunity to work on numerous transcreation projects for brands like Trainline (DUDE London), Slack (in-house studio), Plum (Flying Object) Nike (Creative Translation), DAZN (in-house studio), Nortene (Mouton Noir), Manomano and others.
