Hi, I'm Dennis! 

As a seasoned growth strategist, I help ambitious companies maximize their commercial potential and overcome complex sales and marketing challenges. With over 14 years of experience, I’ve driven significant revenue growth for a select group of clients across various industries.

Since 2010, I’ve partnered with 50+ organizations, including KPMG, ING, Financiallease.nl and VodafoneZiggo, delivering high-impact sales and marketing solutions.

In 2017, I founded a lead generation startup and joined a startup accelerator program, gaining first-hand experience in scaling businesses. I treat every project as my own, ensuring a hands-on, results-driven approach that delivers lasting success.
