AI accelerates code. But without a solid brief, it mostly accelerates mistakes.
At Ylly, we start by understanding your business, your users and your constraints — before writing a single line. The result: projects delivered on time, with no bad surprises, and documentation that belongs to you.

What we can build together
Turn a vague need into an actionable project in 5 days
You have an idea, a problem to solve, a process to digitize — but no specification document yet. We step in upstream to scope, document and prioritize, assisted by AI to move 3× faster.
What you get:
Your site or app no longer reflects who you are? Let's rebuild on solid ground.
Before redoing everything, we audit. Technical, UX, performance, content — we identify what's holding back your growth and produce a prioritized roadmap with concrete recommendations.
What you get:
A digital tool that fits your process, not the other way around.
Client portal, extranet, configurator, internal management tool — we design and build custom platforms for B2B companies with needs that off-the-shelf solutions simply don't cover.
What you get:
AI is changing the speed of development. Not the right to cut corners.
Today, an AI-assisted developer produces in one week what used to take a month. That's good news — as long as what they're building is the right thing.
What we see in the field: projects move faster, design mistakes do too. A poorly scoped requirement generates code twice as fast, and twice as many client revisions. Feedback loops pile up. Budgets slip. Delivery starts to feel like a negotiation.
The problem has never been the speed of development. It has always been the quality of the scoping upstream.
That's exactly where we come in.
Step 1 — Discovery & Scoping
/ We start by listening to you. Really. We map your business, your users, your technical constraints and your business goals. AI helps us structure the information and surface blind spots from the very first conversation.Step 2 — Documentation & Specifications
/ We write a living specification document: user stories, user journeys, business rules, edge cases. Everything is documented, versioned, validated with you. You remain the owner of every decision.UX/UI Design
/ Before a single line of development, you see your product. We create interactive prototypes that you test with your teams. We iterate until everyone is aligned.Step 4 — Development & Delivery
/ Code comes last — when everything is clear. Agile development, regular check-ins, progressive delivery. No bad surprises, no budget overrun at the end of the project.Not sure yet which offer fits your need? Tell us about your project in 2 minutes — we'll point you in the right direction, no detours.
