About Guillaume

Are you leading a deeptech or medtech startup? Your technology is solid. But your non-scientific stakeholders, investors, partners, and early customers don't yet see what it changes for them.
This is a common problem: the more technically proficient you are in a subject, the harder it is to explain it simply. You're missing a narrative. Something that concretely shows what your innovation does in the real world.
This is my profession. I've developed a method for it: the Scenotype. I transform your technology into visual use cases, before you develop, recruit, or raise funds. Scenarios that show how your users will truly experience the product. In their environment, with their constraints, in their words. Not another pitch deck, but visuals that project usage and solidify understanding.
The result:
- Your funder understands effortlessly.
- Your partner signs because they see themselves in the scenario.
- Your users tell you what's missing and what's extra.
- Your team knows what to develop first.
- You de-risk your development and validate your product-market fit before committing budget in the wrong direction.
And it's fast. Usually 72 hours, a week at most. Not months of R&D.
Whether you're preparing for a funding round or a non-dilutive financing application (BPI, regional, national, or European), the ability to make others understand how innovation will change things is what separates a document that gets read from one that gets financed.
My background: CEA, Institut Curie, ENS, a PhD in Health Engineering, then eleven years in deeptech startups making innovations understandable to those without a scientific background. In 2023, with a client, I triggered a product pivot in a few months, leading to 15 partnerships signed: Airbus, ESA, CNES, DGA. In 2026, I helped this same client win 2 funding awards.

Experience

  • Ascendx-DGT
    Deeptech Communication Consultant
    CONSULTING AND AUDITS
    September 2023 - Today (2 years and 11 months)
    • Consultant in strategic deeptech communication for startups in the Go-to-Market phase.
    • Addressing the most common ecosystem problem: solid technology that its creators struggle to explain to non-scientists, with usage hypotheses never tested on actual stakeholders.
    • Classic missions covered: clarifying value proposition, multi-target key messages, content for investors and partners, editorial structuring.
    • Distinctive added value: the Scenotype, a visualized use case scenario inspired by pretotyping (Alberto Savoia). Its benefit is twofold.
    -- On the financing side, it transforms a technological promise into a tangible scenario that funders and investment committees can follow effortlessly, concretely improving the chances of obtaining funding.
    -- On the product development side, it solidifies usage hypotheses into testable propositions before any development, and allows learning in a few weeks what would have cost eighteen months of misguided effort.
    Notable clients: OneTreck (medical pivot → space/defense, 15+ partnerships with Airbus/ESA/DGA), MyNumea (micronutrition).
