Diederik Martens
Chief Marketing Technologist & Founder

I’m passionate about marketing technology, marketing operations, and complex B2B sales. It’s my mission to help others succeed. After my last role as Head of World Wide Marketing Operations at Quintiq, I founded Chapman Bright, previously named SMOps. It was at Quintiq that my team was awarded the international Killer Content Award for our lead nurture strategy with Marketo.

I have almost a decade of daily Marketo experience. I’m the chairman of the official Dutch Marketo user group since 2012. Since then I’ve been named 3x to the Marketo Champion Elite Top-50. I’ve been among the first few individuals to ever get Marketo user certified (MCE). And I’m a Marketo Certified Solutions Architect (MCSA) with several specializations (e.g. integrations).

My LinkedIn Page

Katja Keesom
Senior MarTech Consultant

I enjoy combining an analytical mind, a passion for customer experience and a great imagination into delivering highly relevant Marketing activities. With more than 20 years of experience in different Marketing roles, I have gained a wealth of knowledge and experience in marketing analytics. As (PRINCE2 certified) project manager, I have been involved in delivering several international projects.

Among the projects I delivered was a large international Marketo implementation with custom integrations. It is exciting to experience first hand how Marketing Automation opens up a world of possibilities to unlock data at scale, using that to enhance customer experience and increase the amount of quality leads. And I’m also a Marketo Certified Expert (MCE).

Arjen Segers
Principal Consultant

In the past ten years I’ve been working in international marketing positions. Starting as a marketing & communications consultant at Utrecht University I progressively grew into my last position as marketing manager for a Los Angeles-based publicly listed company. Working out of Brussels, I have covered Benelux, Germany, United Arab Emirates and the Nordics, all with a major focus on demand generation.

Already Marketo Certified, I have experienced the added value of marketing technology myself when our sales teams frequently started hopping by my desk to share the business impact of joint marketing initiatives. By then it was clear that I didn’t want to limit that value to one organization.

After joining Chapman Bright I’ve been working as a Marketo Certified Solutions Architect on large accounts, such as DHL Express and Deloitte.
