Services offered by agence web DualMedia
The agency groups its work into three areas, each with its own team and specialties.
Web development and site creation
The web division handles custom website creation, site redesigns, and web application development. Supporting services include web hosting, UX design, technical architecture planning, and marketing automation.
The agency states that it builds custom sites rather than working from templates, with each project scoped around the client's business objectives.
Mobile app development
Mobile development is the agency's largest division by project count, covered in more depth in this guide to application mobile DualMedia.
Agence web DualMedia builds native applications for iPhone, iPad, Android, and Apple Watch, and offers porting services for companies that have an iOS app and want the same product on Google Play, or the reverse.
It also develops business applications (applications métier) for sales teams and field technicians, digital publishing solutions for tablets, and MVP builds for startups testing a first product.
SEO services
The SEO division, branded as a 360-degree referencement agency, covers search audits, on-page optimization, technical SEO, and content strategy.
The agency positions SEO as a service that runs alongside development work, so a site built by the web team can be optimized by the SEO team from launch. Current SEO statistics show why pairing the two matters for organic visibility.
Clients and portfolio
Client references are the strongest verifiable signal about agence web DualMedia. Its published portfolio includes projects for large European brands across automotive, luxury, and industrial sectors, including the specialist watchmaking segment that generated around 3.28 billion euros in 2024 sales for parent group
Richemont, per data from Statista:
Audi: Audi Pro Mobile, an iPad application for sales support, training, and commercial management.
Seat: a sales support and commercial training application.
Vacheron Constantin: a catalog application combining three product catalogs in eight languages for the brand that is, according to Wikipedia, the oldest continuously operating watch manufacturer in the world.
Etam: an iPad presentation app covering the group's lingerie and fashion brands.
Dassault Systèmes and Kérastase: mobile projects listed among the agency's featured references.
Byblos Saint-Tropez: a client service application for hotel guests.
GICAT: an iPhone and iPad communication tool for the French land defense industry group.
The portfolio leans toward business applications for established brands rather than consumer app launches, which matches the agency's stated specialty in applications métier.
How much does agence web DualMedia cost?
The agency's mobile app pricing page explains that cost depends on how technically demanding the build is, target platforms, design customization, features, security requirements, hosting, and ongoing maintenance. It publishes example ranges rather than fixed rates:
Project type | Indicative price range |
Simple mobile application | €5,000 to €15,000 |
Complex application | €20,000 to €50,000 |
Large-scale application | €100,000+ |
A basic app with few screens sits at the low end. Payments, geolocation, user accounts, APIs, admin dashboards, and cloud infrastructure push a project toward the higher ranges.
The agency offers a quote request form (devis application mobile) for project-specific estimates, and website projects are priced separately on the same scoped basis.
What to check before hiring agence web DualMedia
The agency's client list and 26-year track record are documented, but any development project deserves the same due diligence. Before signing, confirm these points in writing:
Scope and deliverables: what the quote includes, and what counts as a change request.
Code ownership: who owns the source code after delivery.
Timeline: delivery milestones and what happens if requirements change mid-project.
Post-launch support: whether maintenance, hosting, security updates, and bug fixes are included or billed separately.
SEO handoff: whether search optimization is part of the build or a separate engagement with the SEO division.
These questions apply to any agency, and clear answers up front prevent most budget and schedule disputes later.
Who agence web DualMedia is a good fit for
The agency's service mix points to three clear customer profiles.
Startups can use the agency's dedicated startup development offer to build an MVP, a landing page, or a first mobile app. The published pricing ranges give founders a realistic budget floor of €5,000 for a simple product, and the porting service means an iOS-first launch can reach Android later without a rebuild.
Established companies are where most of the portfolio sits. The Audi, Seat, and Etam projects were internal business tools: sales support apps, training platforms, and catalog presentations. Companies that need a custom application for a sales force or field team are hiring the agency for its most practiced work.
French businesses that need local SEO and hosting get both from the same partner. The agency's SEO division handles referencement for the French market, and its hosting service keeps site infrastructure under the same contract as development, which simplifies accountability when performance issues appear.
Agence web DualMedia compared with alternatives
Businesses weighing agence web DualMedia against other options usually compare three routes: a full-service agency, a freelancer, or a website builder. An agency fits projects that need several skills at once, such as a site, an app, and an SEO strategy managed together.
A freelancer costs less for a small, well-defined task. A website builder works for a simple brochure site but cannot deliver custom business applications, native mobile apps, or the technical SEO work that competitive niches require.
DualMedia's positioning targets the first category: companies that want one partner across development, mobile, and search, with references at enterprise level to support that claim.
Conclusion
Agence web DualMedia is a long-established Paris agency with verifiable credentials: 26 years of operation, 200+ mobile projects, and named clients including Audi, Vacheron Constantin, and Dassault Systèmes.
Its three-division structure covers web, mobile, and SEO under one roof. For businesses in France comparing web agencies, agence web DualMedia is a documented, portfolio-backed option worth shortlisting.
