About Guillaume

My expertise: I help commercial and finance teams close better deals, faster: designing governance frameworks, building pricing architectures, coordinating complex multi-stakeholder negotiations, and turning deal data into leadership-ready insights that drive smarter decisions.

In details

1. Deal Governance & Tooling
Designing commercial governance from scratch: delegation of authority, approval workflows, RACI frameworks, and translating them into operational tools. Experienced business owner of Salesforce-based deal tracking modules, from specs to deployment and adoption.

2. Pricing Architecture
Triangulating cost, demand, and competition to build pricing frameworks that work in the field. Fluent across multiple models (SaaS/subscription, revenue share, performance-based...) and expert at designing incentive, rebate, and discount programs that drive the right commercial behaviours without eroding margins.

3. Complex Deal Execution
Coordinating and facilitating complex, multi-stakeholder deals from early commercial scoping to final sign-off, aligning Sales, Finance, Legal, and Product around a shared framework while keeping momentum and discipline at every stage.

4. Commercial Insights & Reporting
Building reporting that actually drives decisions: margin and profitability analysis, deal velocity and productivity tracking, standard vs. non-standard deal monitoring, win/loss rates, and pricing trend analysis, designed for Sales leadership and Finance audiences alike.
