About us

Born in Amsterdam, specialised in technology, hands-on, goals driven, and always looking to give clients the best return on their PR or marketing budget. That is En Serio, the PR & Inbound partner for tech innovators.

We pride ourselves on our decades of experience working with technology companies. And we have built up a wealth of knowledge along the way. This experience and our know-how of your technology, customers and partner ecosystem, help us to craft stories and content that your key target audiences are looking for.

OUR MISSION

Our clients are all innovators with great ideas. They bring innovations that make personal lives, businesses and industries better: smarter, more effectively and enhancing the way their customers do things in a more sustainable way.

To create more impact with their new technologies, we believe that the ideas, stories and visions of our clients need to be heard. We are committed to making that happen through PR and Inbound marketing services that focus on sustainable, long-term relationships with everyone we work with.

We strive to be a ‘good’ company and be an example for people and businesses. Our actions and initiatives reflect our care for the planet and the people that live there: we commit to allocating at least 5% of our time to pro-bono work . We dream and work to inspire others to dare to be good for the world around them. Let’s make it happen together.

PEOPLE + BUSINESS + STORIES

We believe that meaningful connections – between people, businesses
AND stories – can turn great ideas into positive change for everyone.
That is why we are committed to creating relationships that matter.

OUR CULTURE

We believe that our challenger mindset is at the heart of every idea, action and goal. We have a non-stop drive to work smarter, execute more efficiently, be more effective and keep learning – even if we were happy with the results or campaign. This helps us to get better and get things done that might have been out of arm’s reach before. Our values are at the core of how we do things at En Serio.
