About Quentin

I help founders turn complex ideas into brands people actually remember.

After 15 years at the intersection of strategy and execution — co-founding and scaling Eclo (sustainable food), leading brand and marketing at Hoona (preventive wellness) from day one, and advising organizations across industries — I work as a fractional marketing director and brand strategist for companies building something that matters.

I'm not an agency. I'm a former founder who has sat across from investors, built visual identities from scratch, written positioning documents, and managed the full marketing stack — brand narrative to SEO/SEA, social media to B2B partnerships, photography to product storytelling.

I know what it costs to get this wrong, and I know how to get it right fast.

I integrate AI workflows into every engagement — not as a gimmick, but to spend more time on strategic thinking and less on repetitive execution. Faster turnaround, clearer outputs, sharper briefs. I also shoot photography in-house when needed, which means one less vendor and a more coherent visual story.

I work best with founders, brand managers, and leadership teams who need senior marketing thinking without the overhead of a full-time hire.

Experience

  • hoona
    Marketing Director
    HEALTH AND WELLNESS
    January 2024 - July 2025 (1 year and 6 months)
    Tervuren, VB, Belgium
    Joined Hoona as their first marketing hire, with a mandate to build the brand from zero — no positioning, no visual identity, no digital presence. Left 18 months later with a fully operational brand, a live product offering, and a marketing stack the team could own independently.
    • Defined the brand positioning and identity from the ground up, translating a complex and nuanced wellness concept into a clear, compelling market offer non-specialists could instantly grasp.

    • Shaped product definition alongside the founding team, ensuring the service offering was aligned with what the target audience actually needed and expected.
    • Built the full visual identity and brand messaging together with a branding agency — from naming logic and tone of voice to the design system used across all communications.

    • Led the website development end-to-end, briefing and managing the agency, reviewing UX decisions, and ensuring every page reflected the brand's values and positioning.
    • Researched, evaluated, and implemented the reservation and booking management tools best suited to the center's operational model.

    • Produced photography and visual content for digital and print channels, maintaining a consistent and premium aesthetic across all touchpoints.

  • Eclo - Exotic Mushrooms
    Co-Founder / Marketing Director
    AGRICULTURE
    September 2017 - April 2024 (6 years and 7 months)
    Bruxelles, Belgium
    Co-founded Eclo (formerly Le Champignon de Bruxelles) and led marketing for nearly 7 years across every stage of the company — from scrappy early days to a recognized brand in sustainable food with a network of top chefs, wholesalers, and retailers across Belgium.


    Brand & Digital

    • Built and managed the full brand identity: visual system, photography, print materials, packaging, and digital presence — all produced in-house.

    • Led SEO/SEA strategy, social media content, and PR, growing organic reach and brand awareness without an agency.
    • Drove a full rebrand centered on circularity that fundamentally repositioned Eclo in how the industry perceived us — away from niche, toward mainstream sustainable food.

    Growth & Partnerships

    • Secured and nurtured partnerships with renowned chefs and Michelin-starred restaurants, building Eclo's credibility at the top end of the food market.

    • Developed and managed a B2B client base of wholesalers, restaurants, and retailers, combining relationship-building with structured account management.

    Operations & HR

    • Set up Eclo's administrative and HR infrastructure from scratch: processes, contracts, onboarding, and team management as the company scaled.

    • Recruited and managed key team members across production, sales, and communication.

    Innovation

    • Researched new applications for mycelium beyond food — exploring material science, packaging alternatives, and circular economy use cases to identify Eclo's next growth vectors.
  • Laboratoire sur l'agriculture urbaine
    Project manager / Vertical farmer
    AGRICULTURE
    November 2016 - March 2018 (1 year and 4 months)
    Greater Montreal, QC, Canada
    Embedded in one of Quebec's leading urban agriculture labs, working across digital platforms and experimental farming projects at the frontier of city-scale food production.
    • Led the development of cultivetaville.ca, a Quebec-wide platform promoting urban agriculture — managed the project from brief to launch in collaboration with web agency Bon Melon.

    • Redesigned the main lab website (au-lab.ca), improving UX and information architecture to better reflect the organization's scope and credibility.
    • Managed all content creation and editorial animation for agriculturemontreal.com, producing regular articles, project features, and partner coverage.

    • Contributed to the VERTical project — a pioneering vertical hydroponic farm installed on the rooftop of the Montréal Convention and Exhibition Center, one of the first installations of its kind in Canada.
