Who am I

Arthur van Donzel

I am Arthur van Donzel, founder of Toplinegrowth.

My belief: real selling starts with real understanding. Successful entrepreneurs genuinely want to help their customers – not just push a product. The better you understand what drives your customer and the more personalized your approach, the easier and more valuable sales become. People buy from people who understand them. Only when you truly know what moves your customer can you deliver real value. That’s the difference between just selling something and being truly relevant.

With over 30 years of international experience in sales management and executive-level consulting, I help organizations grow revenue, develop go-to-market strategies, build strong teams, and apply AI in sales. I am used to delivering quick value in complex commercial situations.

My approach in three words: Strategic. Human. Accelerating.

My areas of expertise:

Sales management and performance improvement
Smart application of AI in sales, including customer insights, lead scoring, and proposal creation
Improving sales approaches through personalization and customer value focus
Development and implementation of effective go-to-market strategies
Coaching and mentoring of sales and business development teams

“Real sales start with real understanding”

Why I started Toplinegrowth

My motivation for starting Toplinegrowth is twofold. On one hand, I see that commercial teams often lack the guidance they need in a rapidly changing landscape. On the other, I strongly believe that AI and human communication can complement each other in the sales process.

I see entrepreneurs searching for ways to improve their revenue. One of the key strategies is the smart application of AI in their commercial approach (beyond the experimental phase). I help organizations find direction, rhythm, and peace in their sales processes – with personalization and customer value as guiding principles.

I’d be happy to walk this path with you for a while.
