Bumpp is a new brand, built on years of experience. It all started with the collaboration between Heike Braakhuis from Rhamnous, Gerard Hubbers, Harry van Kessel, and the team at SIENN, a trusted software and IT consultancy with more than 20 years of experience.
That collaboration led to the realization that true digital growth only happens when you genuinely work together as partners. That’s what sets us apart. We’re not a traditional agency, but a movement; a strategic and technical extension of your business that helps you grow online with structure, consistency, and trust.
The team at the helm
Together, Heike, Gerard and Harry bring this vision to life, each from their own background and expertise.
As an experienced entrepreneur, Gerard has a sharp eye for what businesses really need. His focus is always on what drives business forward and how to achieve that in practice. He turns opportunities into business that delivers results today.
Heike brings his background as an online sales business developer and his experience in building international communities of specialists. He knows how to combine knowledge and creativity, turn knowledge-sharing into a driver for innovation, and translate it into real business.
Harry adds the technological expertise and methodology to not only create solutions, but also to implement them in a smart, scalable, and sustainable way with his team. He selects the right solutions and ensures they land effectively within companies.
Through SIENN and Rhamnous, we’ve gained years of experience in large-scale projects: bringing international teams together, developing applications with Rapid Application Development, and using technology to truly move SMEs forward.
This experience forms the foundation of Bumpp: pragmatic, proven, and future-focused.
The symphony of people and AI
We believe the future of business won’t be defined by working harder, but by working smarter, with people and AI. That’s why we give entrepreneurs a boost that goes beyond marketing and technology.
We turn creative energy into data-driven strategy and transform ideas into practical execution, strengthened by the power of AI. Bumpp combines experience with vision, connects technology with creativity, and brings people and artificial intelligence together.
AI helps us uncover patterns people usually overlook and create content that perfectly fits your audience. But the real magic happens in the combination of AI and human creativity, because only together do they create impact. The result: the latest technology, fresh ideas, and the right people at the right time.
Digital growth gets a Bumpp
We don’t just guide your growth, we give it the right boost. A Bumpp means momentum, the moment when insight, timing, creativity, and expertise come together to move your business forward, online and offline, with a strong focus on optimization and lead generation. Because in the end, it’s all about business.
The digital world doesn’t stand still, and neither do we. We support your entire online presence, from strategy and brand identity to campaigns and visibility.
