Independent commercial development consultantOpen the markets.Close the deals.
I help consulting firms and B2B SaaS set the commercial direction, put it to work and build the relay — from the first prospecting and closing to ongoing commercial leadership.
How the work develops
Set the direction
The diagnosis
Read the sales system, choose the priorities and write the plan your business needs.
Test in the field
Direct sales, partnerships
Senior, hands-on work to test the market and the offer. Buyer conversations feed the strategy, through direct sales or partners.
Build the relay
Grow the team. Keep direction.
Once the approach is validated, organise the prospecting relay. I can retain discovery, closing and ongoing leadership.
Focused work
Strategy, process, AI
A defined engagement to clarify the strategy, improve a sales process or integrate AI into the team’s work.
The embedded mission · how it runs
From market learning to commercial leadership.
Phase 1
The diagnosis
Your sales system against your stage, then the plan — positioning, message, targets, campaigns, the engine, the stack. It ends in writing.
then the plan, in writing
Two engines
Direct — or through partners
Sourcing to closing on your product, or referral partners, integrators and alliances. The plan says which, or both.

- Sequences

- Alliances
- Co-selling
Three paths
Establish, then lead
I test the approach on the ground. Once the target, process and tools are validated, we organise the prospecting relay. I first retain discovery, closing and follow-up.
- 01
Test in the field
Market, target, offer — learn from buyer conversations.
- 02
Validate the relay
Target profile, process and tools, before delegating prospecting.
- 03
Keep commercial direction
Discovery, closing and follow-up first; leadership as the team grows.
Every week
You see everything
One read a week: what moved, what stalled, what I need from you. The pipeline is yours, live, in your tools.

The relay
A team, with direction
Your team, a recruit, an agency or freelancers can take over prospecting. I can stay to lead the commercial function; the tools and knowledge remain yours.

A day rate for the days I commit; for hands-on execution, a commission on the revenue I bring and trailing rights on the clients I sign. Scoped per mission — quoted, never listed.

When this is for you
A market to explore. A sales approach to establish. A team to strengthen.
- A second product line with nobody senior to open its market.
- A new geography you can't crack from home.
- A founder or a partner who has to step out of the pipeline.
- A team that closes but never sources.
- A market you would rather open through partners than alone.
From inside the team
A revenue leaderin the work —not above it.
Selected work
20+ engagements across Europe and Southeast Asia.
Six of them, in detail — what was true before, what's true now.
Build the engine
A repeatable way to win new projects
Work won only through the partners' relationships and referrals — no pipeline beyond a few weeks.
Now
Pipeline visible 90 days out, sourced through a documented motion — partners no longer chasing every lead.
Market entry
Expansion into the Singapore market
Strong on home turf, but no route into neighbouring markets — and no read on Singapore buyers.
Now
Servicing the first Singapore clients, with a localised offer and an outreach the team runs.
Market entry
Opening Southeast Asia for an Italian manufacturer
A solid European business, but no foothold, network or channel anywhere in Southeast Asia.
Now
First distributor and direct-account targets engaged across SEA — groundwork in place to start winning.
Channel program
A partnership program for a payments platform
Growing on direct sales alone — channel leverage untapped, new merchant segments out of reach.
Now
Channel program live and signing partners — distribution no longer capped by direct-sales bandwidth.
Integration partnerships
An integration partnership program
Needed distribution by embedding inside other apps — but no motion, no target list, no deal framework.
Now
Integration partnerships now a repeatable channel — first platforms shipped, the process documented.
Full-cycle leadership
Full-cycle sales leadership
A bank-backed B2B SaaS needing hands-on sales leadership across the full cycle.
Now
Running the end-to-end motion with the founders — helping them decide when to bring it in-house.
We'd been talking about fixing sales for two years. Guillaume came in and did it. Within a few weeks we had a real pipeline and a process the team could run on their own.
Client names withheld at their request — sector, region and stage instead.
