About Guillaume

I automate your processes (n8n/make) with AI: email sorting, CRM, back-office, follow-ups, reporting.

I also connect tracking & attribution (GA4/GTM, UTM, Pixel/CAPI) to transform traffic → leads → sales.

I am a CMO/CMDO (14 years) and CRM & automation consultant: I help marketing & sales teams structure their CRM, industrialize the lifecycle, and accelerate growth (B2B/B2C) through simple, measurable, and maintainable processes.

References & impact: at Octika, I led an omnichannel strategy and digital transformation (multilingual e-commerce, CRM integrations, marketing automation) with +50% revenue and +99% traffic.

For the past 2 years, I've also had a strong "product builder" role: I design and deliver digital products end-to-end, from short projects (audit + prototype + quick wins) to more ambitious and complex systems (e.g., modular platform like NutraVector), with an AI-first approach (agents, automations, pipelines, integrations).

What I do most often
• growth marketing: SEO, CRO, acquisition, content, landing pages, nurturing
• CRM & lifecycle: segmentation, scoring, pipelines, governance rules, marketing automation
• tracking & measurement: GA4, GTM, UTM, conversions, pixel/CAPI if needed, KPI dashboards
• product building: scoping, specs, user stories, prototyping, iterations, delivery
• applied AI: AI-boosted automations, advanced agents and workflows, API integrations

Stack & tools
  • automation: n8n, make, zapier (workflows, retries, logs, alerts)
  • data & ops: notion, airtable, google sheets, drive
  • CRM & lifecycle: hubspot (or equivalent CRM), activecampaign, zendesk (pipeline, scoring, nurturing)
  • tracking & analytics: GA4, GTM, UTM, conversions, dashboards (looker studio)
  • integrations: webhooks, rest API, oauth2, field mapping, json
  • applied AI: chatgpt / openai, prompts, agents, AI-assisted automations (classification, summarization, extraction)

Experience

  • NUTRAVECTOR
    Founder / Product Builder
    HEALTH AND WELLNESS
    January 2024 - Today (2 years and 7 months)
    NutraVector is an AI-first B2B SaaS platform project for the nutraceutical industry (brands, contract manufacturers, suppliers). Objective: digitize and accelerate the complete cycle from sourcing to compliance, formulation, industrialization, and market launch, with a "workflow" approach and strong GDPR requirements.

    Role: founder / product builder

    • Discovery & scoping: market research, problem statements, segmentation (brand / contract manufacturer / supplier personas), journey mapping, KPI definition, and MVP scope.
    • Product design: modular functional architecture, prioritization (impact/effort), backlog, user stories, specifications, acceptance criteria, go-to-market strategy, and pricing hypotheses.
    • No-code / low-code build: rapid prototyping, user testing, iterations, integrations, automations (workflows, notifications, scoring, dashboards).
    • Applied AI: design of specialized assistants per module (co-pilots), data extraction & structuring (technical documents, ingredient sheets), classification, scoring, deliverable generation, logging (audit trail), and safeguards.
    • Data & compliance: entity modeling, document quality/traceability, multi-country requirements, consent management, access security (multi-tenant, roles, validations).

    Project Complexity (what is actually built)

    • multi-stakeholder product with different business logic (brand vs. contract manufacturer vs. supplier) and collaborative workflows,
    • structured data layer + documents + automations + AI, with a need for reliability and traceability,
    • "premium" experience: guided onboarding, dashboards, standardized processes, reduced time-to-market.
    Typical Deliverables
    MVP roadmap, functional specifications, prototypes, journeys, automated workflows, data schemas, product documentation, and execution plan.

  • Laboratoire BioCeutics
    FOUNDER
    HEALTH AND WELLNESS
    January 2022 - Today (4 years and 7 months)
    BioCeutics is a nutraceutical brand/lab that I created and developed from scratch, with a strong "growth" and performance-oriented approach (acquisition, conversion, loyalty). The project covers the entire chain: product positioning, branding, go-to-market, Amazon sales, and AI-assisted marketing automation.

    Role: founder (strategy + operational execution)

    Brand & product marketing: nutrition-health positioning, value proposition, visual identity, packaging, brand content, key messages, and differentiation.

    E-commerce / Amazon: product listing optimization (Amazon SEO, title/bullets/A+ structure), conversion strategy (proofs, benefits, FAQ), performance monitoring, and iterations.

    Paid acquisition: Amazon sponsored campaigns (structure, targeting, optimization, cost control), "test and learn" logic, and quick wins prioritization.

    AI applied to marketing: deployment of an AI stack to accelerate production and quality (ideation, copywriting, visuals, creative variations, A/B tests, template standardization).

    Data & optimization: KPI tracking (traffic, conversion, ROAS/ACoS, reviews), continuous improvement based on data, repurchase rate optimization, and customer satisfaction.

    Results (key achievements)

    +4,000 units sold on Amazon in 12 months

    customer satisfaction 4.7/5 and repurchase rate 35%

    objective achieved: > €60,000 in annual revenue from the first year without significant external media budget

    Project Complexity
    Creation of a brand from scratch + implementation of a complete growth system: content and assets, Amazon SEO, advertising, conversion, continuous optimization, and industrialization of marketing production via AI (processes, templates, automations).
