Bold thinking, clear strategy, and no-fluff consulting – for companies ready to evolve.

Who’s the Sloth?

The Gluttonous Sloth is the consulting and training alter ego of Martin Kubler – a strategist, trainer, and advisor who helps businesses rethink, refocus, and reset.

I work with startups, SMEs, and independent businesses that are growing, stuck, or somewhere in between. My approach is simple: cut through the noise, uncover what matters, and move forward with clarity and purpose.

How I Work

I help businesses untangle complexity, sharpen positioning, and make clearer strategic decisions — whether that means fixing what’s stuck, preparing for growth, or navigating change.

Sometimes clients come with a clearly defined problem. Often, they just know something feels off. That’s usually where the best work starts.

What I Believe

  • Clarity over complexity
  • Strategy over theatre
  • Curiosity over convention
  • People over process
  • Progress over perfection

Who I Am (The Longer Read)

I’m a strategic consultant and trainer with over 30 years of international experience across Europe, the Middle East, Africa, and Asia.

My background blends business, hospitality, branding, customer experience, and organizational change. I’ve trained executive teams, coached startups, and advised everyone from founder-led businesses to fast-growing brands.

“In another time and place, I’d have made a great consigliere or grand vizier. Today, I’m a great consultant and advisor instead. Less dramatic title. Similar results.”
