Coen Vleesenbeek – Franchisor
For over 20 years, Coen has dedicated his career to improving business performance and driving value creation — working with SMEs and large corporations alike, both locally and internationally. With a foundation in accountancy and consultancy for small businesses, he’s also held senior roles in finance, marketing, and e-commerce across the Netherlands, Australia, and the United States.
In 2007, Coen made the decision to focus his efforts exclusively on supporting SMEs. Seeing the positive impact of his approach — and recognising a wider appetite for doing the same — he launched thexton armstrong in the Netherlands in 2011. After nearly a decade of growth, he handed over the leadership to trusted partners in 2020, and has since turned his attention to expanding the franchise internationally.
Today, Coen’s mission is to empower experienced professionals to build successful consultancies under the thexton armstrong brand — helping SME owners thrive, while creating personally fulfilling and financially rewarding careers for franchisees.
We’re here to support you at every step—whether you’re looking to grow, recover, or prepare for exit. Let’s talk about how our methodology can work for you.
