When the signal is loud & clear 🎛️
Most scale-ups call Overdrive when at least two of these are true
If it feels painfully accurate for you too, well…I think we should have a talk!
-
Your GTM exists, but feels chaotic
Growth is real, but the engine is running hot. Sales pitch varies by rep, marketing can't keep up, and product decisions lack market input.
-
Positioning tries to please everyone
Your ICP is "companies who need our all-in-one best of breed product." Your messaging sounds like everyone else. Prospects nod politely, then ghost.
-
Product, Marketing & Sales work in silos
Sales blames marketing. Marketing blames product. Product wonders why sales "just doesn't get it." Sound familiar?
-
You're scaling internationally...and it's not working
You translated the pitch. You hired local sales. But EU or US expansion is burning cash without traction. The playbook isn't landing.
-
PMM is stuck on execution, not strategy
Your PMM (if you have one) is drowning in decks and blog posts. No time for positioning. No mandate for leadership. No wins.
-
You need senior PMM leadership, not another junior hire
Recruiting takes 3-6 months. You can't wait. And honestly? You're not even sure what "great PMM" looks like yet.
Stop treating symptoms. Fix the structure.
Overdrive doesn't create more slides or run more campaigns.
I address the structural problems holding back your growth.
-
A clear, prioritized GTM with real execution discipline.
-
Sharp positioning & ICP definition that sales actually use.
-
A messaging framework understood across Product, Marketing & Sales.
-
Market, competitive & win-loss insights guiding strategy.
-
A structured PMM function with cadence, ownership & impact.
-
EMEA and US GTM adapted to local markets, not just translated.
This is about clarity, alignment, and leadership, not more activity and noise
Three ways to work together

What's included:
Senior PMM leadership (3-4 days/week)
Critical initiatives kept moving

Strategic & operational PMM leadership, 3-6 months
What it is:
I step in as your Product Marketing Leader with a clear mandate: structure your positioning, align your teams, build GTM discipline, and scale the PMM function.
This isn't support. This is leadership, with ownership, accountability, and senior-level execution.
What's covered:
Building Product Marketing from scratch (0 → 1)
International expansion & market localization (EMEA ↔ US/CA)
GTM strategy & competitive intelligence
Scaling existing PMM teams (coaching, process, roadmap)
What you'll have at the end:
A go-to-market that's clear and pilotable
Positioning & messaging that sales teams use (not ignore)
Product / Marketing / Sales working together, not in silos
A PMM function ready to scale, with or without me
Investment:
From €700/day · 3-4 days/week · 3-6 months
Custom engagements available. And if you prefer hourly engagement that’s possible too.
Who it's for:
Scale-ups (50-200 people) that need senior PMM leadership without rushing a full-time hire.
→ Let's discuss your GTM needs.
Let's be honest
this isn't for everyone.
Fractional leadership only works with clarity, trust, and ownership.
If you're looking for any of these, we're not a fit:
❌ Pure execution resource: "We need someone to do the slides."
❌ Short-term lead generation fixes: PMM doesn't solve a leads problem.
❌ A PMM without decision power: I need mandate, not tickets.
❌ Micromanagement or low-trust environments: Leadership requires autonomy.
❌ Early-stage startups (1-20 people): Your problem isn't structural yet. Let’s start with advisory.
I work with teams ready to structure, decide, and invest in their Product Marketing and Go-to-Market.
