I’m Marcus, a growth operator and former VC. Over the past decade, I’ve worked with fast scaling SaaS and fintech companies to turn strong traction into repeatable, structured growth.
Today, I partner with high-growth teams as a hands-on advisor and interim executive, aligning marketing, sales, success and product.
My focus: building sustainable, defensible go-to-market engines, while driving commercial excellence and sales effectiveness.
Where I Add Leverage

GTM is founder-led and/or not repeatable | GTM execution: Building a scalable growth engine from 0→1 and beyond | Built the first top-down sales motion for a SaaS company already generating strong self-serve revenue.

How I Work
Fractional & Interim Roles
I step in to lead and accelerate core commercial functions (hands-on execution with a strategic edge, often for companies between funding rounds or during key transitions)
- Commercial & GTM Leadership across Marketing, Sales, Customer Success & Product
- VP Growth, CCO or COO roles, tailored to your team structure and goals
Strategic Advisory & Sparring Partner
For founders and investors looking for an experienced operator to:
- Stress-test strategic decisions
- Shape commercial playbooks and build scalable operating models
- Act as a trusted advisor or board-level sparring partner
Project-based Consulting
- Market entry & international expansion
- Investor readiness & due diligence
- Business model audits & strategic repositioning
I typically work with VC-backed companies from Series A to Series C (EUR 5 to 50m in revenue), or during PE-led transformation.
How I Think
I build systems. I question defaults.
I think GTM isn’t just about hustle - it’s about fit.
I think product and commercial teams should talk daily.
I think great pricing is more powerful than great branding.
I think AI should be used aggressively, not aspirationally.
I’ve seen too many boardrooms run on optimism and opinions. I bring structure and clarity.
B2B Only. No Exceptions.
I work exclusively with fast-growing SaaS and fintech companies scaling their products, teams, and markets.
- AI-native & SaaS Companies
- Fintech & Financial Services
- Enterprise Software & Applications
- Industrial Automation and Robotics
- Professional & Technology Services
- VC & PE-backed Portfolio Companies
Beyond scale-ups, I selectively advise corporates in financial services, insurance and industrials on AI strategy, venture/M&A and growth initiatives.
What Makes Me Different
Cross-functional depth: I operate across GTM, product and finance - not in silos.
Strategy + execution: I don't just advise but ship, test and build with your team.
System thinking meets automation: I think in systems, not slides. I automate aggressively and use AI to reduce complexity, speed up delivery, and skip unnecessary headcount.
Let’s Talk
Know what you need? Or just know something’s off? Book 30 minutes - we’ll figure it out together (worst case: you leave with more clarity than when you arrived. Espresso is on us.)
