Your website is often a prospect's first contact with your company: it has to convince quickly, on mobile as well as at a desk. We design showcase websites and B2B platforms that are fast, accessible, secure and measurable, then maintain them over time — updates, backups, changes. Design, build and ongoing support, delivered in Paris and Île-de-France.
Dated design, slow pages, broken rendering on mobile: a prospect comparing several providers forms an opinion before ever calling you. For a B2B company, a neglected website contradicts the sales pitch — a redesign brings the first impression back up to the level of your services.
The site exists, but nobody knows what it produces: how many visits, where they come from, how many contact requests convert. Without measurement, there is no way to arbitrate between redesign, content and acquisition — the web budget is spent blind.
A CMS that is never updated, vulnerable plugins, an unreachable provider, lost credentials: every change becomes a project and every flaw stays open. An unmaintained site degrades — in search rankings as in security. Contractual maintenance replaces that drift with documented, ongoing upkeep.
A useful website starts with scoping: commercial objectives, target audiences, visitor journeys. The design then serves that structure — not the other way round.
A clean technical foundation: fast to load, readable by search engines and usable by everyone, including on mobile.
A company website is run as a service: monitored hosting, encrypted traffic, updates applied and backups verified.
The site produces data: visits, sources, contact requests. That data feeds your decisions and changes to the site, with visitor consent respected.
The exact scope, deliverables and timelines are formalised in the proposal, before any commitment.
Objectives, audiences, existing content, technical constraints and timeline: the scope is set before anything is priced.
Site structure, desktop and mobile mock-ups, choice of technical foundation. Mock-ups are approved with you before development starts.
Iterative build, performance and accessibility checks, and testing on mainstream browsers and devices before sign-off.
A prepared cutover: redirects from the old site, checks on search indexing and forms, and a rollback plan.
Updates, backups, monitoring and regular reviews: the site evolves with your business instead of ageing.
The answers describe how the service works. Quantified commitments are formalised in your contract.
