Bio

For over 15 years, I’ve helped B2B startups and scale-ups in Europe and the US move from product-market fit to predictable, profitable growth. I understand the chaos and complexity of scaling, and how to turn it into clarity, focus, and momentum across Marketing, Sales, and Customer Success. If you’re a founder, C-level, or marketing leader navigating your next growth phase, I start with one simple rule: diagnose before you prescribe. Through a focused GTM & Marketing Audit, I help you identify what truly drives impact, and what doesn’t. We review positioning, ICP clarity, funnel health, channel efficiency, and team setup, to pinpoint constraints and create an actionable growth roadmap. From there, I help you: Build strategy that sticks: translate vision into measurable actions, aligned KPIs, and clear ownership. Align revenue teams : unify Marketing, Sales, and CS around one customer journey and language. Control your economic: use data, attribution, and CAC payback to guide where to double down or pull back. Develop people and performance: grow, train, and retain high-impact teams that deliver growth, even without big budgets. Growth happens when strategy, execution, and people move in the same direction. That’s what I help you unlock: with structure, speed, and substance. Let’s start with an chat, and audit and see what’s really driving (or blocking) your growth.

Expertise


  • Building a team

    One of the most underrated performance potential for younger businesses is to prioritise hiring the right people, and to keep them engaged, and thriving. Down the line, you won't get your customers to stay engaged with your services if your people aren’t engaged, and if you face high employee turnover. Seeking and seeing the potential in people is my fuel.

  • Content marketing

    B2B buyers are just people like you and I. When they seek a service or a product that isn’t part of their core business, they can feel overwhelmed. By creating an experience that gives buyers the control they expect and prefer, not only you will solve their business problem, but you will also allow them to have a clear picture of their return on investment. Content is key to develop supporting awareness, educational, impactful material that speaks your audience's language.

  • Conversion rate optimisation

    Do you have access to data touchpoints highlighting your customer lifecycle to ultimately provide a higher customer experience and to scale your business by taking the right decisions and actions based on analytics? How does your team track the user journey today and do they have access to the tech tools required to meet your ambitions?

  • Customer success

    Positioning Customer Success to contribute directly to revenues, loyalty, and a higher customer experience. Performing On-boarding, impact, and retention objectives, and a client development track aligned with clients and internally at your company, Customer Success turns into a main revenue driver.

  • Go to market strategy

    Start with your competitive and market research, identity your ideal client profile in the new market, potentially launch with a partner if it fits your model, realign your product analysis, product messaging, the sales proposition, marketing strategy and the sales strategy.

  • Growth marketing

    Create awareness, education, and impact experiences for your audiences so that you create trust in the market, and with your client. Growth Marketing helps you focus on fostering client loyalty. And in B2B customer loyalty lays in the purchase experience of your product or service.

  • Mindset coaching

    Personal leadership and a mindset of performance are coachable, and will make the people in your organisation go the extra mile, develop themselves, have a sense of purpose and belonging, and contribute to your collective success.

  • Product launches

    Cascade your strategy down to your product launches. How to align departments on a project management level with deadlines, executions, and common success goals to track, to improve on and to improve.

  • Venting frustration

    Most SaaS/ Tech companies grow fast. Such companies don't always focus on employee satisfaction. Stress, communication issues, a bad manager, lack of sense of belonging, etc. Let's talk about it.
