About Guillaume

I help companies with their business development by assisting them in acquiring new clients and structuring their prospecting strategy.

I manage end-to-end prospecting missions: CRM deployment, targeting, multi-channel actions, results analysis, and concrete recommendations.

Specializing in the commercialization of technical solutions, I work particularly with companies in the IT sector.

My strength lies in a human, artisanal, and long-term vision of customer relationships. I have a gentle, empathetic, and psychological approach to sales. My 14 years of prospecting experience have solidified my conviction that by focusing on the means rather than the results, one builds a satisfied clientele that stays and recommends.

Thus, I dedicate a significant part of my time to deepening the argumentation, analyzing and optimizing processes, and understanding the prospect and their environment.

If you wish to implement an effective long-term customer acquisition structure, do not hesitate to contact me.

My status as a Disabled Independent Worker will allow you to fulfill your CSR commitments while reducing the cost of my services.

    SEVENTIC

    Activity: Commercial prospecting agency focused on large accounts

    Seventic contacted me to outsource a prospecting mission for a unified platform editor for finance, purchasing, and procurement. The editor is a challenger in the market and targets large companies, mostly listed in the CAC-40 or SBF 120. The agency needed a sales expert in B2B appointment setting, capable of navigating large accounts to identify and reach decision-makers in these large companies (purchasing, logistics, finance), and to generate appointments quickly.

    Skills Deployed:
    • Integration – enrichment – extraction of several business and contact prospecting files.
    • Structuring – configuration of a CRM for the needs of complex prospecting in large companies.
    • Multi-channel prospecting – creation of email templates specific to each stage of prospecting. 15% email response rate.
    • Account mapping: reporting identified contacts, decision-makers, decision-making processes, and existing equipment.
    • Detailed weekly reports and end-of-mission summaries: analysis of offer reception, file quality, target and discourse adjustment.

    Performance Indicators:
    • Number of days worked: 14.5, including 10 days of prospecting
    • Calls: 808
    • Decision-makers identified: 31
    • Pitches: 27
    • Actions to be taken: 10
    • Appointments generated: 5

    My generated appointments led to opening cycles in large companies, which can generate high added-value sales in the medium term for Seventic's final client.

    Rennes, France
    Activity: Outsourced commercial prospecting agency

    Context: FSG contacted me because they were facing a peak in activity requiring a Senior Salesperson expert in IT B2B lead generation, available immediately. They entrusted me with the management and execution of a qualified appointment-setting campaign on behalf of a cybersecurity editor.

    Skills Deployed:
    • Development of a telephone interview guide/sales pitch based on the briefing and provided documentation.
    • Speech training through AI-powered telephone interview simulations, with progressive difficulty. This innovative approach led to a rapid increase in the conversion rate.
    • Telephone prospecting on the client's CRM. Organization/prioritization of prospecting to optimize the contact rate, which is usually low for a target of 500-1500 employees.
    • Real-time enrichment/updating of the client's database.
    • Regular reporting and updates allowing for reactive adjustments in tandem with the campaign manager.
    • Drafting summary sheets for opportunities identified.

  • Paris Digital School
    Structuring and business development - student recruitment
    EDUCATION AND E-LEARNING
    November 2024 - June 2025 (7 months)
    Paris, France
    Activity: Business school offering a leading BAC + 5 degree in digital, e-business, and marketing

    Context: In a full development phase since its founding two years ago, the school engaged me to recruit students to fill its classrooms. Facing strong competition, the school was building its reputation and therefore needed an experienced salesperson to structure and manage the recruitment cycle autonomously.

    Performance Indicators:
    • Mission duration: 74 days
    • 780 contacts processed
    • 3159 calls
    • 385 contacts pitched
    • 238 contacts interested in the program
    • 30 students registered for the school's open days
    • 25 applications submitted
    • 3 students enrolled in the program
    • €24,000 in revenue generated for the school.

    I managed the entire campaign from A to Z, completely autonomously:
    • Configuration of a custom CRM for intensive, organized, and tracked prospecting needs: statuses, custom properties, email integration...
    • Development of email sequences corresponding to all stages of the prospect journey, with a style and language adapted to the student/digital marketing target (9% response rate).
    • Multi-channel prospecting: email, phone, LinkedIn, WhatsApp. International calls, including several interviews in English.
    • Regular video activity reports.
    • Recommendations to refine the sales and communication strategy.

    My collaboration with Paris Digital School generated a direct return on investment in under 12 months and the implementation of an effective and sustainable prospecting structure.
