Our services
Our services for European associations and institutions
Institutional websites
Your website must hold up when a Commission decision-maker opens it on their phone between meetings. We design editorial architectures built for your institutional audiences (members, press, funders) with a CMS your teams manage alone, without calling a developer.
Institutional visual identity
A visual charter for a European association must work from the annual report to cabinet meeting presentations. We deliver a complete visual system, not an isolated logo — and your teams retain ownership of all source files.
Printed advocacy materials
A position paper placed on a cabinet meeting table must be read in three minutes and retained. We design materials where layout serves the message, not the other way around.
Why specialize
An association does not communicate like an SME
Its audiences are multiple (members, political decision-makers, specialized journalists, funders) and its messages must hold up in three languages, in a meeting room in Brussels just as in a report sent to Strasbourg.
Multilingualism is not a box to check at the end of a project. Neither is editorial governance: your teams change, mandates rotate, and the site must remain manageable without calling a developer every time you need an update. WCAG compliance, GDPR, sovereign European hosting—these are real constraints, not sales arguments.
A generalist agency can deliver a nice website. It doesn't understand why your position paper must be ready before the trilogue, or why your visual identity must work just as well on a roll-up at a press conference as in a PDF sent to the Commission.
Simpl. has been working with this type of organization since 2005. We know these challenges from the inside.

Frequently Asked Questions
Do you work exclusively with Brussels-based associations?
No. Our clients are based in Brussels, Paris, Berlin, Geneva, Strasbourg — wherever European associations and institutions are located. The concentration is strong in Brussels because that's where most of European advocacy happens, but location is not a criterion. All our projects are managed remotely without any loss of quality: briefing, mockups, validations, training — everything is done remotely. Our most distant clients have never come to Brussels once.
How do you manage editorial governance when teams change every 2-3 years?
It's the most underestimated constraint in European associations, and we know it well. Our answer is structural: we configure the back-office so a new communications officer becomes autonomous in under an hour, with no technical training. Every delivery includes written documentation tailored to your organization — not a generic WordPress manual. We train your existing teams at delivery, and that documentation remains valid for future ones. The goal: staff turnover never blocks a website update.
Do you support multilingualism FR/EN/DE on association websites?
Yes — and we build it in from the start, not tacked on at the end. That's a crucial difference: a multilingual site added after launch creates architecture problems, content duplication, and maintenance headaches your teams pay for for years. We design the information architecture, page templates, and CMS with the number of languages in mind from day one. Result: adding or updating a translation requires no technical intervention. Your teams manage FR, EN, and DE content from the same back-office, with no risk of breaking the site structure.
