About Valentino

Tellement Studio is an independent web studio based in Croix-Rousse, Lyon. We design and deliver complex web products for SMEs, SaaS project leaders, and companies that want a custom-made internal tool or B2B product.

Scope covered:
· B2B SaaS platforms, from MVP to v1 delivered in production
· Redesign of existing web products (legacy, stack migration, complete rebuild)
· Internal tools and business dashboards (backoffice, workflow, admin tool)
· Premium editorial sites and custom e-commerce stores when the project warrants it

Studio differentiators:
· Payment only after client approval of the mock-up. If the visual direction is not convincing, the client leaves without owing anything.
· A single point of contact from brief to delivery, no subcontracting.
· Modern stack (Astro, Next.js, Node, TypeScript, PostgreSQL, Cloudflare front-end, European infrastructure back-end).
· AI in the loop for design and development, senior-level requirement for deliverable quality.
· Stated deadline in the quote and met, in writing from the start.

Three-act method: the brief, the mock-up, the production. The client approves the mock-up before any payment; the studio develops, hosts, and maintains.

For whom: SMEs of 5-50 people, SaaS project leaders, product teams needing a senior technical voice to deliver complex web products without burdening their structure.
