At a glance
Founded in northern France in 1853, Lesaffre is the world leader in yeast and fermentation — the invisible engine behind one loaf of bread in three, on every continent. It is a quiet giant: essential everywhere, recognised almost nowhere.
And yeast doesn't stop at bakery. The same living micro-organism raises dough, ferments wine and beer, feeds animals, powers nutritional supplements and sits at the heart of modern biotech. It is one of the most versatile ingredients on the planet — and one of the least understood. Ask anyone what yeast actually is, and the answers run out fast.
Lesaffre came to us with a deceptively simple ambition: modernise how the world sees yeast, and make people grasp the sheer breadth of what it makes possible — for their global B2B customers and for the wider public.
Yeast is essential and everywhere, yet it carries an image problem: invisible in the final product, vaguely “chemical” in the public mind, and boxed into “the thing that makes bread rise.” For a company whose science reaches into food, health and biotech, that perception was far too small.
The brief also carried a natural first instinct: ride the momentum of modern food culture — plant-based, vegan, kombucha, fermentation-as-lifestyle — to make the category feel young and relevant again.
The trend-led, alternative-food audience feels like the whole conversation. The evidence said it was a small slice of the market — and building a global brand on it would aim at the edges instead of the centre.
Before committing a global brand to a trend, we tested it. We ran an international market study across five countries, benchmarked comparable food products, and mapped the real attitudes people hold toward what they eat.
The picture was clear. The lifestyle tribes everyone talks about — strict vegan, “biohacker,” alternative-fermentation enthusiasts — are genuinely small slices of the population. What unites the vast majority instead is broader and more durable: a pull toward naturality, tradition and honest, unprocessed food. Anchoring Lesaffre's whole brand in the trend would have chased a narrow edge and left the centre untouched.
To make that usable, we translated the data into eight consumer personas — distinct attitudes toward food, from Care and Health to Purpose, Nostalgy and Performance — so every team could see exactly who they were, and weren't, talking to.
Instead of borrowing a trend, we gave the category its own conviction. Yeast isn't a niche ingredient chasing fashion — it's a natural superfood with genuine super-powers: a best-in-class nutritional profile, the ancient science of fermentation, and a role that is local and natural by design. One idea, big enough to lead with, and true across every application.
A conviction only works if the portfolio can carry it. We built a brand architecture that puts YEAST at the centre as the category brand — the pillar that feeds both the direct yeast products (fresh, dry, nutritional yeast, sourdough…) and a family of endorsed brands, each one visibly “powered by yeast.” It gives Lesaffre a single, ownable story and a system that scales across markets.
Most food brands photograph the finished plate — the bread, the beer, the glass of wine. We did the opposite. To make an invisible ingredient visible, we made the raw material itself the subject: yeast shot as sculpture, its texture pressed and imprinted to suggest each application without ever showing the end product.
A fork drawn in a bed of yeast. Blocks of fresh yeast stacked like stone. The company name embossed into the powder, as if it had always been there. A warm, restrained palette does the rest — signalling natural, healthy, sustainable and safe, and giving Lesaffre a visual language no competitor owns.
The result: a coherent brand platform that gives a century-old, invisible ingredient a modern, ownable identity — one story that travels from a global B2B audience to the supermarket shelf, grounded in evidence rather than trend.
