About Guillaume

You are leading a deeptech startup. Your technology is solid. But your non-scientific contacts, investors, partners, and early customers don't yet see what it concretely solves for them.
This is a communication problem: the curse of knowledge. The more you master a subject, the less you know how to talk about it simply. Your contacts are not lacking intelligence. They lack a narrative that concretely shows them what your innovation changes for them.

My job: transform your innovation into visual and narrative use cases, BEFORE you develop, recruit, or raise funds. Visual scenarios that show how your users will truly experience your product: on their ground, with their constraints, in their words. Not PowerPoint slides. Not another pitch deck.

Result?
- Your funder understands effortlessly.
- Your partner signs because they recognize themselves in the scenario.
- Your product team knows what to develop first.
- And you've tested your product-market fit without burning €150k in the wrong direction.

Background CEA, Institut Curie, ENS, PhD in health engineering, then ten years in deeptech startups explaining innovations to non-scientists. With a client in 2024, reformulating the use cases was enough to trigger a complete product pivot and sign 15 partnerships in a few months: Airbus, ESA, CNES, DGA.

Experience

  • Ascendx-DGT
    Deeptech Communication Consultant
    CONSULTING AND AUDITS
    September 2023 - Today (2 years and 9 months)
    • Strategic deeptech communication consultant for Go-to-Market startups.
    • Addressing the ecosystem's most common problem: solid technology that its proponents cannot explain to non-scientists, and whose usage hypotheses have never been tested with real stakeholders.
    • Typical missions covered: value proposition clarification, multi-target key messages, content for investors and partners, editorial structuring.
    • Distinctive added value: The Scenario-type, a visualized usage scenario inspired by pretotyping (Alberto Savoia). Its value is twofold.
    -- For funding, it transforms a technological promise into a tangible scenario that funders and investment committees can easily follow, concretely improving the chances of obtaining funding.
    -- For product development, it solidifies usage hypotheses into testable propositions before any development, and allows learning in a few weeks what would have cost eighteen months of wrong direction.
    Notable clients: OneTreck (medical pivot → space/defense, 15+ partnerships Airbus/ESA/DGA), MyNumea (micronutrition).
