If you are an early-stage founder looking to move fast without burning runway on product design, this is worth 3 minutes of your time. I explain what Ghostudio is and why I think it's the only resource that fits the way technical teams build today.

AI SOLVED EXECUTION. IT DID NOT SOLVE DESIGN THINKING.

Technical teams can now build and ship at a pace that was impossible months ago. AI solved the execution layer. What it did not solve is the thinking behind how a user encounters a product, navigates its complexity, and keeps using it.

WHY THIS MATTER NOW
Technologies are failing on experience, not on functionality.

The product works but users still cannot find the value fast enough, and struggle to confidently take the actions that matter. It happens in AI-native applications, developer tools, data platforms, fintech and Web3 ecosystems. Anywhere the technology is powerful, users need guidance to unlock its full potential. Today's pace of execution accelerates incoherence in experiences. For early-stage teams with fresh funding and a market to prove, every interaction with the product is a signal. Getting the experience right is not a luxury. It is part of the proof.

AI enhances design expertise but it cannot replace it.

The instinct is to solve product challenges with more AI guidance. It does not work that way. AI amplifies the skill already present. In the hands of an expert it becomes a force multiplier. But without a solid design foundation, it generates misalignment faster. The judgment behind what to build, how a user thinks, where confidence breaks, that comes from experience. It cannot be prompted or generated. It has to already exist.

The traditional design resources were not built for the ai era.

A full-time senior level hire means months of recruiting and costs ~$150k/year for a time-bound challenge. Agencies take 3 to 6 months and charge $50-150k to deliver files that still need dev interpretation. Most freelancers are task-level executors and don't propose an outcome-based plan. None are suited for startups that need versatile design resources for the speed of AI. There is a gap between what the problem requires and what these options deliver. That gap is exactly where Ghostudio operates. It is simply a smarter capital allocation.

A new kind of resource
Design intelligence for the AI-native era

Ghostudio is an AI-native product design studio. It helps founders translate powerful technology into intuitive product experiences their users understand immediately.

It does this through outcome-based design cycles. From UX architecture through to production-grade interfaces and token-based systems, everything is delivered at AI pace, built to be immediately actionable in your existing stack.

The model is designed for early-stage teams. It works as a long-term partner who stays close to the product vision, steps in precisely when the work needs to happen, and steps back when it does not. It is a senior level input without the permanent overhead, so your runway goes where it matters most.

FRACTIONAL BY DESIGN. SENIOR BY DEFAULT.

I am Guillaume, but everyone calls me "G". It is the first UX optimization I offer. I have been in the field for 15 years working as a design leader mostly for VC-backed startups in London.

Most of my career has been spent at early-stage teams where design had to move fast, land credibly, and help unlock what came next.

Always collaborating with founders to bridge the gap between technology and market. I am often seen as the magician because I know how to turn complexity into beautiful simplicity. My collaborators call this "G-fying problems."Always collaborating with founders to translate technology into the product experiences they deserve. I am often seen as the magician because I am good at turning complexity into beautiful simplicity. My collaborators call this "G-fying problems."

I was lucky to be exposed to the AI space early. In 2018 I joined Papercup as Principal Designer to create one of the first AI translation tools. Since then I followed closely how AI was developing in the field. In 2025, as I was building a traditional agency myself, I realised how product development cycles changed and the way we always approached design services needed to change too.

So I repositioned Ghostudio around one belief:

The most valuable design intervention is a specific phase with a defined outcome, delivered as close as possible to the codebase, with senior thinking applied at the exact moment the product needs it the most.

I restarted this from scratch, alone. The plan is not to grow headcount, hire anyone available, and dilute what makes this work. Ghostudio will stay a boutique studio of elite designers. So every engagement gets the same level of thinking and craft.
