Get to know us

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.

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.

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.
