AI-powered web agency for European organisations
Websites that lighten the workload for your teams
Your website shouldn’t just provide information. It should answer questions, support your teams, speed up content publication, simplify multilingual management and help your visitors find information quickly. Simpl. is an AI-powered web agency based in Brussels and dedicated to European organisations. Since 2005, we have supported over 80 European organisations – with institutional websites, visual identities and advocacy materials. Today, we integrate AI directly into our processes and into the websites we deliver.

Our services
Our services for European associations and institutions
Smart institutional websites
Your website is often the first point of contact with your members, partners, journalists or organisations.
It must enable your team to publish content easily, remain compliant for years to come, and respond quickly to visitors.
We design websites that:
- Reduce the time spent on publishing content
- Make the work of communications teams easier
- Remain adaptable despite changes in management
- Incorporate AI where it adds real value
Institutional visual identity
A logo on its own is not enough. A European organisation needs a coherent visual identity system that can be applied across all its media – from conference slides to annual reports.
- Audit of the existing system and strategic recommendations
- Creation or redesign of the logo and its variations
- Comprehensive brand guidelines: typefaces, colours, usage rules
- Visual identity system adaptable for web, print and presentations
- Online access to source files to maintain the graphics unit
- Usage guide to be shared with your teams and service providers
Printed advocacy materials
A poorly laid-out position paper will not be read. An annual report lacking visual hierarchy will not be taken seriously. Form serves the message.
- Position papers, policy briefs, fact sheets
- Annual reports and activity reports
- Institutional brochures and meeting materials
- Structured layout for quick reading and retention
- Print and PDF versions optimised for digital distribution
Embedded AI
7 AI features for your teams
These days, a website should do more than just provide information. It should also support your teams: reduce repetitive tasks, speed up publication, and automate whatever can be automated.
“The most significant change is that AI is no longer used solely to speed up our work. It is becoming a feature of the website itself. Today, we deliver websites capable of helping their users: conversational search, information-based chatbots, assisted content generation, translation, SEO optimisation, intelligent internal linking and the automation of certain editorial tasks.
At the same time, AI enables us to produce more consistent interfaces, speed up certain design phases and make maintenance easier.
But the real added value lies elsewhere: we are now designing websites that continue to deliver value after they go live, helping teams to communicate more effectively and visitors to find the information they are looking for more quickly.”
Nicolas Havenith
Founder of Simpl.
Here are the seven AI features that Simpl. incorporates into corporate websites:
Your visitors can find an answer in a matter of seconds
They no longer have to scroll through dozens of pages. They simply ask their question. The website provides an answer based on your approved content.
Knowledge-based chatbot
Cut down on repetitive queries directed at your team. The chatbot responds solely based on your content. No making things up. No unvalidated replies.
Publish simultaneously in several languages
Your team approves. The AI prepares the text. Translators only step in when necessary.
Intelligent translation
Publish in several languages without endless back-and-forth with your translators. AI-assisted translation cuts turnaround times and costs while keeping editorial control in human hands.
Be found on Google... and on AI search engines
We optimise your content not only for traditional search engines but also for ChatGPT, Perplexity and new conversational search engines.
Process automation
Scheduled publishing, forms connected to your CRM, automated newsletters, approval workflows: your editorial and administrative processes run without repetitive manual work.
Compliance by design
GDPR, the AI Act, WCAG 2.2 AA: these requirements are built in from the design stage, not bolted on at the end of the project. It is more robust, less expensive, and it avoids unpleasant surprises during an audit.
Technology choice
We build websites that are ready for what comes next
Choosing a technology is our job — not yours. We advise you based on how you actually work, who is on your team, and where you want to be in three to five years.
WordPress
- Simple administration, no technical training required
- Mature ecosystem, proven plugins
- Built-in SEO, multilingual with Polylang
- Scalable and easy to maintain over time
- Ideal for the vast majority of European associations
Next.js
- Maximum technical performance (optimal Core Web Vitals)
- Complex web applications and bespoke interfaces
- Ideal for high-traffic projects or advanced features
- Headless architecture, decoupled CMS possible
We choose together, based on how you work — not on our own technical preferences.
AI prototypes
Have you built a prototype with Lovable, Bolt or v0?
Lovable, Bolt, v0, Replit — these tools let you build a visual prototype in a matter of hours. It is an excellent way to validate an idea, show a direction to your board, or test an architecture.
But a prototype is not a production website. That is not a criticism: it is simply a technical reality.
What’s missing between a prototype and a fully-fledged website:
- Easy administration
- Search engine optimisation
- Accessibility
- GDPR
- Maintenance
- Documentation
- Performance
- Security
- Scalability
“The problem is usually not the quality of the prototype. These tools produce a very convincing result quickly. The difficulty appears when the project has to live on. Teams want to change content, add features, manage several languages, improve their search rankings or hand the website over to a new colleague. That is the moment when the limits of a prototype become visible.”
Nicolas Havenith
Founder of Simpl.
What Simpl. does:
Managed by your teams, with no dependency on a developer
SEO-optimised, structured to be found
WCAG 2.2 AA compliant — real accessibility, not a statement of intent
GDPR compliant — consent, cookies and personal data handled properly
Hosted in Europe, on sovereign servers
Documented, maintainable, built to evolve
We don’t just create websites. We design communication platforms that enable your teams to publish content more quickly, engage more effectively with their audiences and remain self-sufficient for years to come.
Why specialize
Why European organisations need a different website
A European association does not communicate in the same way as an SME. Nor does it communicate like a public institution. It addresses audiences simultaneously who do not share the same expectations, the same languages or the same levels of expertise.
Your requirements are specific:
- Diverse audiences: members, policy-makers, journalists, donors, the general public – each group engages with your website differently and is looking for different information.
- Multilingualism is non-negotiable: English is often the working language, but French, German or other official EU languages may be required depending on your target audiences.
- Complex editorial governance: teams change, mandates rotate, and communications managers come and go. The CMS must be self-sufficient, well-documented and transferable.
- Actual compliance: WCAG 2.2 AA, GDPR, hosting on sovereign European servers: these are not optional extras, they are the bare minimum.
- Institutional timing: a legislative agenda, meeting cycles, and publications relating to the work of the European Parliament or the Council. Your website must keep pace with this, not the other way round.
Nicolas Havenith — Founder of Simpl.
"We design websites to be independent of the people who use them. In practical terms, we implement a clear editorial structure, reusable page templates, a consistent design system and a streamlined administration process. Content is organised according to business logic rather than technical considerations, so that a new communications manager can take over quickly without having to relearn how the entire site works.
Artificial intelligence also provides invaluable support: it can assist teams with writing, translation, information retrieval or content updates, whilst adhering to the existing editorial structure. The aim is to maintain the website’s consistency despite changes in personnel."
Nicolas Havenith runs the Brussels-based agency he founded 20 years ago. He advises European organisations on their institutional websites, visual identity and digital communication strategy.

Frequently Asked Questions
Combien coûte un site web pour une association européenne ?
A realistic price range for a professional corporate website is between €5,000 and €12,000, depending on the number of pages, languages, features and the level of graphic customisation. A multilingual website with integrated AI features generally costs between €6,000 and €15,000. We will provide a detailed quote within 48 hours of our initial discussion.
How long does it take to create a corporate website?
Between 6 and 14 weeks, depending on the complexity of the project. A standard corporate website (5 to 15 pages, bilingual, using WordPress CMS) is delivered within 8 weeks. More complex projects – such as multilingual sites, those with AI features, or those including a rebrand – take 12 to 16 weeks. We tailor the schedule to your organisational deadlines.
Can our teams manage the website without any technical skills?
Yes. This is a non-negotiable requirement in our approach. We deliver a CMS that can be managed by any member of the team, complete with clear documentation and training included. The aim is for your team to be self-sufficient from the day after delivery.
Do you offer maintenance services after delivery?
Yes. We offer monthly maintenance contracts that cover security updates, backups, performance monitoring and a set number of hours for enhancements. Maintenance is optional but strongly recommended for an institutional website in production.
How do you integrate AI into a charity website?
based on your actual needs. We start by looking at how you use the system: what questions does your team encounter most frequently? What content do you publish on a regular basis? Which processes are repetitive? From there, we select the relevant AI features – conversational search, knowledge-based chatbot, multilingual writing assistance, automation – and integrate them into the CMS so that your teams can use them without the need for specialist training.
