Often, the problem isn’t a lack of marketing. It’s a lack of direction.

As companies grow and change, marketing and communication often become more complex too.

More services. More stakeholders. More channels. More ideas.

But not always more clarity.

You may recognise this if

  • your positioning no longer reflects the business;
  • marketing, sales and leadership are not always working from the same direction;
  • strong expertise is difficult for the market to understand;
  • marketing and communication have become reactive;
  • there is plenty of activity, but not enough focus.
You may not need more marketing.
You may need clearer choices, stronger alignment and a better way forward.

How I can help

I help you step back, look at the bigger picture and bring clarity to what really matters. From there, we can sharpen the direction, align the right people and turn that into practical priorities your team can actually work with.

Positioning

Clarify where you compete, who you need to reach and why they should choose you.

Marketing & Communication

Turn the strategy into focused marketing, communication and customer journeys that support the business.

Alignment

Get leadership, sales, marketing and communication around the same priorities.

Execution

Turn direction into clear priorities, ownership and execution, then learn from what works.

Clarity. Direction. Alignment. Execution.

Fractional or Interim Leadership

Make sure it actually happens.

I’m Katja De Witte, founder of Accretios and a B2B Marketing & Communication Director.

My career took me from hands-on marketing and communication to senior international leadership roles at companies including Stork, Microsoft and Air Liquide.

I have led international teams, advised executives and worked across marketing strategy, positioning, go-to-market, communication, stakeholder engagement and marketing operations.

I understand the boardroom because I have been there.
I understand execution because I started there.
