Grow Your Agency With Our White Label Services

Are you a digital marketing or SEO agency and need a reliable technical partner to develop your clients’ websites? We build high-performance white label websites that strengthen your marketing and SEO campaigns.

Our custom-coded sites deliver exceptional performance that your clients will notice immediately. Loading times under one second, perfect PageSpeed scores, and clean code that boosts organic search rankings.

What Sets Us Apart

Mobile-First Design

We build every site starting with mobile screen sizes. This approach allows fluid adaptation to all screen formats by letting content expand naturally rather than compressing it artificially.

Fully Responsive

All our sites display perfectly on any screen size, from smartphones to ultrawide monitors. Our custom code gives us precision and control impossible with site builders or WordPress themes.

Guaranteed PageSpeed Optimization

Loading times are crucial today. We are experts in speed optimization. No superfluous code: every line is written with intention and optimized for performance. We contractually guarantee scores of 90+ on all four Lighthouse metrics.

Complete Maintenance

We handle all modifications. Your clients can contact us directly or you forward their requests to us. We take care of everything so you can focus on your agency and strategy.

Custom Integrations

Whatever platform or CRM you use, as long as they have an API, we can integrate your booking services, calendars, or email marketing into our custom sites.

Multilingual Team and International Experience

We work in French and English, allowing us to collaborate effectively with agencies in France, the UK, and the United States. Our team has solid experience collaborating with Anglo-Saxon agencies and understands the cultural and technical nuances of different markets.

Fluid communication in your language, adaptation to time zones, understanding of local standards and expectations: we make your work with international clients or expansion into new markets easier.

Our Process

We handle everything from A to Z to simplify your work.

Step 1: Comprehensive Questionnaire

We send a detailed questionnaire about your client’s business: activity, services, differentiation, objectives. This allows us to understand what we need to communicate on the site.

Step 2: Design Validation

Once the design is created, we present it during a screen-sharing session before showing it to your client. We ensure it matches 100% of your expectations and strategy before the reveal.

Step 3: Development

After adjustments from the design phase, we develop the site and all its pages. Once ready, we share a demo link for validation before going live.

Step 4: Launch and Support

We handle the launch, DNS configuration, professional emails, and all technical aspects. Your client receives a turnkey site, and we remain available for future modifications.

Two Collaboration Models

Direct Referral

You refer your client directly to us. We handle the entire project from end to end as well as post-launch support. You remain the main agency for marketing and SEO strategy; we are your technical arm.

Pure White-Label Collaboration

We work directly with you in the background. Your client does not know we exist. All communications go through you; we execute what you ask. You keep total control of the client relationship.

Why Our Sites Perform Better

No Bloat, Only Useful Code

Unlike WordPress themes or Webflow sites that generate thousands of lines of unnecessary code, we write only what is necessary. The result: sites that load instantly.

Systematic Image Optimization

We optimize every image on the site for mobile and desktop. Modern formats (WebP, AVIF), adapted dimensions, intelligent compression. Your clients benefit from beautiful visuals that do not slow down the site.

Built-In Technical SEO

Semantic HTML structure, Schema.org structured data, optimized meta tags, exceptional loading speed. We build the perfect technical foundation for your SEO strategies.

Superior User Experience

Fast sites offer a better user experience, which improves Google rankings. If a site takes too long to load, visitors leave before even seeing the content. Our sites eliminate this problem.

Our Lighthouse Guarantee

Performance - 90+/100

Accessibility - 90+/100

Best Practices - 90+/100

SEO - 90+/100

We put this guarantee in writing in our contracts. Find another agency that commits to such high scores. There are some cases where we cannot achieve a perfect score: integration of complex Google Tag Manager scripts, e-commerce with numerous backend features, or heavy video integrations. But for static informational sites, we systematically launch with 98-100/100.

“I have worked with Geoffrey on a number of occasions to help with work for my own agency and, as a fellow developer, can speak nothing but praise about his abilities as a developer, designer, and agency owner. His designs are beautiful, his technical skills and knowledge are second-to-none, and his attention to the finer details around accessibility and performance are very rare to see in the web community.”
Ethan Hawes, Founder of Test Valley Digital (UK)

Frequently Asked Questions

  • How does billing work?

    Two options: either we bill your client directly (in the case of a direct referral), or we bill you and you rebill your client with your margin (in the case of a pure white-label partnership). We offer preferential rates for agencies we collaborate with regularly. The more we work together, the more advantageous the terms.

  • Can you work with our existing Figma mockups?

    Absolutely. If you already have designs validated by your client, we can develop directly from your Figma mockups. We faithfully respect your design choices while optimizing the code for performance.

  • Do you offer white label support after launch?

    Yes. Your clients can contact us directly (if you wish) or all requests go through you and we handle them in the background. In all cases, we remain invisible and you keep the credit with your client.

  • How many projects can you handle simultaneously?

    We voluntarily limit the number of ongoing projects to guarantee quality and meet deadlines. Generally, we can handle 3 to 5 simultaneous projects depending on their complexity. We inform you of our availability before accepting a new project.

  • Do you offer training on site management for our teams?

    Yes, if your client wants to manage certain aspects of the site themselves (with Shopify Headless for example), we can train your teams or directly your client on dashboard usage and best practices. Training available in French and English.

  • Do you work with agencies outside of France?

    Yes, we have solid experience collaborating with agencies in the UK and the United States. Our team is perfectly bilingual French-English and understands the cultural and technical nuances of different markets. We easily adapt to time zones and Anglo-Saxon working methods.
