The Giarte story

For over 15 years, Giarte has been a leading research and consultancy agency for IT experiences. We work with technology companies, public organizations and large corporations, around the world. We make actionable what really counts in business IT: customer satisfaction, user experience and trust.

In the Netherlands, we are well known for IT Xperience: the annual, independent comparison of customer satisfaction in outsourcing. The customers of over 40 service providers participate in this extensive audit. The IT Xperience monitor (ITX) is a valuable benchmark and trend report in the Dutch IT market.

Creators of the XLA®.

Giarte is the founder of the innovative Xperience Level Agreement. The XLA® orchestrates IT by impact and user experience. The focus on processes and technology makes way for what matters most: employees, customers and the business.

Justin Mensah

Junior Consultant

Favorite saying: “Hard work pays off.” Probably the best-dressed office tiger there is. A star when it comes to connecting the dots in a complex analytical consulting engagement.
