Our approach
A website must generate leads, not just impress.
Most websites are glorified brochures. Visually nice, strategically empty. At Solentia, every design decision (hierarchy, CTA, content) is conversion-oriented, not aesthetic.
We start from your business objectives to design a content architecture, then a design system, then code. Every component is built for performance (Core Web Vitals), technical SEO and autonomous editing via CMS.

On average 6 to 8 weeks from brief validation to production launch. Design phase: 2 weeks. Development: 4 weeks. Testing and launch: 2 weeks. This timeline can vary depending on complexity and how quickly you approve each phase.
100% custom. Every project starts with original Figma mockups, a design system built for your brand, and code written from scratch. No WordPress theme, no Webflow template. The result: a unique site optimized for your goals.
Yes, redesign is one of our most common use cases. We first audit your current SEO to preserve all authority. We map URLs, configure 301 redirects, preserve backlinks. Your traffic should not drop after the redesign.
Yes, it's planned from the start. Sanity CMS lets you edit text, images and content blocks in a few clicks, without touching code. We include a 2h training session at delivery. Developers remain available for structural changes.
Technical SEO is native to our stack. Dynamic meta tags, Schema.org JSON-LD, automatic XML sitemap, semantic HTML, optimized next/image, Core Web Vitals in the green. For content SEO (keyword strategy, copywriting), that's a complementary service.
Every project is different, and we don't publish a price list. Budget depends on the number of pages, features, integrations and the level of customisation required. The best way forward: a 30-minute brief to assess what you need together, then a clear and detailed quote within 24h. No commitment.
SMEs, startups, professional firms (lawyers, doctors, architects), e-commerce businesses, creative agencies, associations. Our specialty: companies that want a website that works for them, not just exists.
