All about who we are and what drives us @ Sound of Data

'Niet lullen, maar poetsen', a Dutch saying that fits perfectly with our Rotterdam roots. We’re eager to make things happen instead of just talking about it. That’s why we’ve made it our business to keep adding value to the customer service voice channel. The only channel with a real human connection.

Management Team (f.l.t.r.): Jos van Loo (CEO) and Thomas Hazelaar (Chief Technical Officer).

Back in the days

Sound of Data was founded in the early 1990s by our current CTO’s father. Way before mobile phones became mainstream and everyone was still calling from landlines. When you could still write a letter to customer service instead of an email. Social media as we know it didn’t exist yet.

Big Dutch television used our platform to manage telephone voting and avoid phone network crashes because of high volumes (Google ‘Henny Huisman-effect’). You could call our information service lines to find out the exact time, weather forecast and to set an alarm. Yes, those were the days.

As technology evolves

Since then, technology has evolved massively and so has Sound of Data. Fast forward to today! Large corporate brands, media companies, and charities optimize their customer contacts with a diverse range of our voice and omnichannel solutions. Both in the Netherlands and abroad.

Their international customer service centers rely on our knowledge and expertise when it comes to infrastructure, telephone numbers, intelligent routing, and overload solutions. They use Talk to turn their telephone channel into an online channel and XCALLY to manage their omnichannel interactions in one user-friendly platform. Our self-service online portal Gearbox gives them the insights and data they need to make smart decisions.

Focus on what you do best

What hasn’t changed since the beginning is the fact that we’re still based in Rotterdam and still a privately owned business. Our customers describe us as very proactive and service-oriented. Got a problem? They know we’ll fix it. Any time of day. If we think their operation can be improved, we won’t hesitate to tell them. That’s why many of them have been with us for years and why we scored an NPS of 72 in our most recent customer satisfaction survey.

And why we continue to innovate so our customers can focus on what they do best, delivering the best customer service possible. Without worries.

"We can turn customer service into a money-maker by using a tool like Talk. It allows us to measure how telephony contributes to online conversion. I can’t think of a nicer mix of customer contact, sales, and marketing."

"At Ticketmaster we regularly experience incoming call overloads when popular concerts go on sale. With Sound of Data’s Overload Solutions, we can handle these peak calls ourselves even with 3,000 eager customers calling at the same time. No other supplier can offer such a reliable service so easily."
