IT'S TIME TO SELL & SCALE TOGETHER
Fractional Sales Leader for European companies and tech startups in the US
European companies and founder-led startups entering the US market face critical challenges:
1. Their US market experience and expertise are limited.
2. Their sales strategy lacks real-life validation through execution.
3. Their resources (people, time, and money) are limited.
These companies may:
Rely on the founder to keep selling.
This can limit scale and create bottlenecks.
Send European team members to the US.
They may not understand American buyers or sales culture.
Deploy junior or lower-cost sales resources.
They often lack experience and need more guidance.
Hire expensive or misaligned salespeople.
American professional hires who can't bridge the US and European cultural gap.
Hire strategy consultants.
They typically provide the strategy without sales execution support.

FREQUENTLY ASKED QUESTIONS
A fractional sales leader works as your part-time VP Sales, providing hands-on execution at a fraction of the cost of a full-time hire. Unlike a full-time VP Sales ($200K-$300K+), I work on a monthly retainer basis with flexible engagement models.
The key difference:
I'm not just executing...
I'm bringing my global expertise and experience to deliver results and build your team's capability using the MMASS Framework.
You get immediate results plus long-term organizational capability, without the commitment and cost of a permanent executive hire.
This is ideal for European companies (especially UK and French) entering the US market or tech startups scaling beyond founder-led sales.
You're a good fit if:
-
You have product-market fit in your home market and are ready to expand
-
You need someone who executes, not just advises
-
You want to build organizational sales capability, not just hire a salesperson
-
You're willing to invest 3-12 months
You're NOT a good fit if:
You're looking for a quick fix or just want strategic advice without execution.
-
Engagements typically run 3-12 months or more, depending on your goals and current situation.
We customize based on your needs.
Some companies need intensive 3-month sprints to launch, others need 12 months to build full infrastructure.
Time commitment varies by engagement model, but generally I work hands-on with your team (building pipeline, closing deals, hiring, coaching...) while developing organizational capability.
We'll discuss the right structure during our initial conversation based on where you are and where you want to go.
The Core MMASS (Motivations, Mindsets, Attitudes, Skills, Solutions) is my proprietary framework for building sales acumen across your entire organization—not just your sales team.
Here's how it works:
I assess the 5 MMASS success factors across all teams (sales, solution consulting, implementation teams...). Based on the findings, I coach and train to help them improve their impact within the sales cycle. That's the multiplier effect.
MMASS ensures your whole organization becomes sales-capable, which means sustainable growth after I transition out.
