About Clement

HubSpot & CRM Consultant | RevOps, Sales Ops & Automation

Consultant in HubSpot, CRM, and RevOps, I help B2B companies harness the full power of HubSpot, structure their sales operations, and automate time-consuming tasks.

My hands-on approach: I start with a clear audit of the existing situation, identify friction points, discuss with your teams, and deploy genuinely useful optimizations aligned with your business reality.

The goal: a clean, coherent, and reliable HubSpot, supported by mastered automations (Zapier, Make, n8n, APIs).

🟠 HubSpot - Audit, migration, optimization

  • Comprehensive audit of your instance (pipelines, properties, workflows, data)
  • Migration of your current CRM to HubSpot (or from Excel)
  • Pipelines, properties, governance, and object organization
  • Reliable reporting, forms, and tracking
  • Data cleaning and quality for a reliable pipeline

🟠 Sales Ops & RevOps

  • Structuring of the sales process and the actual sales cycle
  • Lead scoring, sales automation, and advanced workflows
  • Dashboards and centralized performance monitoring
  • CRM adoption and best practices for your teams

🟠 Automation & Integrations

  • Intelligent automation between HubSpot and your tools (Zapier, Make, n8n)
  • Tool synchronization (Aircall, LinkedIn, PennyLane...)
  • API connection and custom workflows

🟠 Cold email, database reactivation & nurturing

  • High-performing cold email sequences in HubSpot
  • Database reactivation and nurturing
  • Segmentation, enrichment, and automatic qualification

🟠 Why work together?

  • +20% closing rate on average
  • 15 to 40 hours saved per month through automation
  • Hands-on approach, direct without intermediaries

    • Setup of a complete n8n workflow triggered by webhook, handling OAuth2 authentication, real-time lead retrieval via API, and processing.
    • Automatic creation of contacts and deals in HubSpot for each request, with deduplication (updating existing contacts without overwriting data) and automatic contact-deal association.
    • Differentiated management of various request types (ad contact, property search) with conditional routing and dedicated business logic for each.
    • Automatic enrichment of records by retrieving listing information (address, area, reference, responsible agent) and assigning to the correct contact based on defined rules.
    • Generation of summary notes pinned to each deal to provide sales teams with a complete overview.
    • Production robustness: reformatting numbers to international format, data cleaning, error handling, and edge case management.
    • Skills: n8n, HubSpot (CRM API, custom properties, workflows), REST API integration, OAuth2, process automation, RevOps.

    Paris, France
    E-raccordement, a B2C service for connecting to the Enedis grid, needed to stabilize its HubSpot CRM before rolling out to four new sites.

    I conducted a comprehensive audit of the instance (workflows, properties, pipeline, reporting), then led the RevOps and Sales Ops implementation: redesign of the sales pipeline, migration and stabilization of automation and follow-up workflows, dynamic document collection form, standardization of contact and deal views and records, and structuring of a dual payment flow via Stripe.

    Objective achieved: a clarified, documented, and cleanly replicable CRM, with stabilized lead assignment and operational processes for the teams.
