B2B Sales & GTM Leader · ANZ & EMEA

William
Prudhon

Enterprise Sales · Account Management · GTM Consulting

8+ years building revenue across ANZ and EMEA — from closing CAC 40 enterprise accounts to leading the largest expansion deal in an ANZ portfolio. I specialise in protecting recurring revenue, expanding accounts, and closing complex deals that require executive relationships and commercial precision.

Beyond execution, I bring a diagnostic lens: I help organisations and founders identify why customers don't convert or don't stay; and fix the handoffs between sales, onboarding, and delivery before they become expensive. In French, English, and German.

What I offer

Where I create value

Revenue expansion

Upsell, cross-sell, and multi-year contracts that grow account value; not just renew it. I find revenue others leave on the table.

C-suite relationships

I engage at CFO, VP Finance, and Supply Chain level; building trust-based partnerships across CAC 40 and Fortune 500 accounts.

Churn prevention

I identify delivery risk early and lead recovery before escalation. Retained NZD 1.2M ARR across at-risk enterprise accounts.

Multi-market reach

Native French · Fluent English · Advanced German. I own enterprise accounts in markets where language barriers stop others.

Full-cycle ownership

Prospecting through QBRs, renewals, and scope expansion; I own the full commercial lifecycle without hand-holding.

GTM diagnosis

I help B2B founders identify why customers don't convert or don't stay; then fix the handoffs between sales, onboarding, and delivery before they become expensive problems.

Also available for consulting
Sales & delivery alignment

Most early-stage B2B teams don't have an acquisition problem — they have a positioning and execution alignment problem. I surface that fast; usually in the first conversation.

Also available for consulting
Scaling with confidence

I pressure-test GTM assumptions before they become costly; helping teams between traction and scale understand what breaks first when volume doubles.

Background

The career in brief

The big picture
From Paris boardrooms to Auckland enterprise accounts

My career has been built around one thing: making enterprise accounts grow. I started in client delivery, learning how deals actually land on the ground; then moved into sales at HubSpot in Dublin, where I went from BDR to AE closing across EMEA. From there I moved up-market — managing some of France's most complex CAC 40 accounts at Anaplan, engaging CFOs and VPs across LVMH, Airbus, Renault, and Stellantis. Today I'm based in Auckland, leading enterprise sales across the ANZ market for Thinkproject. Three continents, three languages, one consistent track record.

Enterprise accounts
Managing complexity at the highest level

I've spent years working with some of the world's most demanding organisations — classified defence entities, luxury conglomerates, aerospace leaders. These accounts require patience, precision, and the ability to navigate politics as well as commercial conversations. I thrive in that environment.

Quota & growth
Consistent overperformance; every time

119% at Thinkproject. 120% at Anaplan. 130% at HubSpot. Not a fluke; a pattern. Whether it's a high-velocity SMB environment or a slow-burn enterprise renewal negotiation, I find a way to close above target.

ANZ market
Closing the biggest deal in the portfolio

Since relocating to Auckland, I closed a NZD 2M, 10-year licence upsell on an existing enterprise account; the largest expansion deal in the ANZ portfolio. I also retained NZD 1.2M ARR across accounts that were at serious risk of churning.

Beyond execution
A diagnostic lens on conversion and retention

Across multiple B2B environments, I've developed a sharp eye for where revenue quietly leaks — the gap between what sales promises and what delivery executes; the positioning mismatches that kill conversion; the handoff failures that drive churn. I bring that lens to consulting engagements with founders and scaling teams.
