The challenge

As Dentsu’s international footprint expanded, their existing website no longer reflected their global ambition and modern brand identity. Following a major rebrand, the legacy site felt misaligned with who Dentsu X had become – an innovation-driven, internationally recognised agency.

While their internal design team had created a striking new visual direction, rebuilding the website in-house proved unfeasible within the tight 12-week timeframe. Dentsu X needed an experienced partner capable of delivering a high-performing, culturally adaptable global site at speed, without compromising on design fidelity or flexibility.

Our approach

Dentsu X initially planned to manage the rebuild internally, but after consulting with our team and reviewing our recommendations, they chose to outsource development to IDHL to relieve pressure and accelerate delivery.

Developing design concepts

Taking the sophisticated, design‑led concepts produced by their graphic design team, we translated them into a robust digital format—carefully considering typography, spacing, interaction patterns, and the technical nuances required for a seamless web experience.

Best-in-class Umbraco solution

We recommended Umbraco as the platform of choice: scalable, license‑free, and perfectly suited to global content operations. To meet the aggressive timeline, we developed the site in phases—launching priority pages as static versions first, with a plan to make all areas fully editable post‑launch.

Supporting an international experience

Given the site would support approximately 50 cultures, scalability and localisation were central to the solution. We built a centralised model with granular permissions so global teams could manage shared content while local markets controlled their own pages, preventing duplication and ensuring consistency.

The site also supported a vast range of languages, so we implemented enhanced editing controls, enabling teams to adapt text colour and presentation based on layout and overlay requirements.

The results

Successfully built and launched to meet the 12-week timeframe, Dentsu X now have a website that reflects their size, international scale, and they are perfectly positioned to satisfy their educated users.
