The foundation to scale, BUX 2022

BUX brand book spread

The scenario

BUX is Europe's fastest-growing neobroker. Since 2014, the Amsterdam fintech has been teaching new generations a simple lesson: investing isn't as hard as they were told. Almost a decade in, that lesson was being taught across 8 European countries. In 2023, BUX wasn't trying to disrupt the market anymore: it was setting up to lead it - and leadership starts with a foundation strong enough to scale. Nine years of fast growth had pulled the identity in directions of its own, into a brand that no longer read as one: the brand wasn't ready to scale.

The approach

The brand book wasn't a refresh, but the foundation BUX didn't have. We started with a full audit, examining every surface BUX showed up on across multiple markets, and the drift was specific: typography varied surface to surface, colours had loosened and the brand assets had stopped being recognisable. Against that, we built the first BUX brand book - covering positioning, tone of voice, key messages and visual identity. One source of truth, digital and print. We delivered a tightened system: a sharpened colour palette, a smaller set of typographic weights and sizes, and illustrations placed under rules of their own - kept in context, used the right way. A more mature BUX, a brand that re-earned its real trust. Not just a book - but the maturity and consistency BUX needed to scale.

The impact

The brand book gave BUX what nine years of growth hadn't: one version of itself. Every market, every surface, every asset now speaks from the same source of truth - a system tight enough to move at the speed of the business instead of trailing behind it.

Health starts in your guts, MDL Fonds, 2024

MDL Fonds brand hero

The scenario

1 in 4 Dutch people lives with a condition affecting their stomach, intestines, liver, or pancreas - not a niche statistic, but a national reality. And yet, for decades, the conversation around gastrointestinal health remained quiet, stigmatised, and largely invisible. Having raised close to 20 million funds over the last 2 years to scientific research and treatments that aim to improve people's lives, Maag Darm Lever Stichting needed to stop presenting itself as a passive fund. As advocates for better healthcare, it was time for Maag Darm Lever Stichting to own its role as the leading force in gastrointestinal health in the Netherlands - and we, DPDK, were all in for it.

The approach

DPDK brought into the table full repositioning - strategy, identity, name, and everything in between. Maag Darm Lever Stichting became MDL Fonds and a new scalable, approachable and human brand has emerged. The identity earns its distinctiveness from the inside out and was built around a single creative decision: the logo itself is formed by the three organs at the heart of the digestive system - stomach, intestines, liver - abstracted into a mark that is both medical in meaning and bold in form. A system of patterns was derived to carry the identity across every surface - from the brand book and website to merchandise, communications, apps, public toilets and national events - turning biology into visual language. MDL Fonds brand doesn't just talk about the body, but it's an identity colourfully shaped by it.

It's a brand story human enough to feel. Loud enough to matter.

The impact

MDL Fonds launched not as a fund asking for donations, but as a movement across the Netherlands. One unified and powerful brand story now travels across every touchpoint - campaigns, hospitals, and fundraising platforms, replacing years of fragmentation and giving gastrointestinal health a presence it never had before. What was once a quiet, clinical fund has become a bold, human voice - proof that even the parts of us we don't like to talk about deserve an identity worth paying attention to.

The extra design mile

The image world took the same conviction and the creative direction pushed it even further. A single, unexpected material: clay. Organic, malleable, and warm - it mirrors the digestive system's own nature, and the possibility of reshaping it through research and care. Just as clay can be molded and reshaped, the digestive system can be nurtured through innovation and treatment - a quiet but powerful metaphor for everything MDL Fonds stands for. The material's handcrafted quality also does something the clinical world rarely manages: it makes vulnerability feel safe. Approachable. Human. Art directed with intention and brought to life with AI, the resulting images translate one of the most stigmatized topics in healthcare into something people can actually look at, connect with, and feel. Not in spite of the subject matter - because of it.

Human enough to feel. Loud enough to matter.
