The Giarte story

Get to know us

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 counts in business IT: customer satisfaction, user experience, and trust.

Founders of XLA

Giarte is the founder of the innovative Xperience Level Agreement. XLA is a powerful addition to the traditional IT Service Level Agreement (SLA). One that builds on the SLA concept by measuring human sentiment and using this to break down silos and think and act from the perspective of a user.

IT Xperience Monitor

In the Netherlands, we are well known for the IT Xperience Monitor: the annual, independent comparison of customer satisfaction in outsourcing. 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. View all results of the ITX Monitor and participating IT providers on the ITX website.

Misha Weber


Favorite saying: "No llores porque ya se terminó, sonríe porque sucedió.” (Don’t cry because it’s over, smile because it happened). Misha has traveled through almost every country in Latin America. His experience abroad has helped him to develop the ability to connect with people from varied backgrounds quite easily. His main goal is to improve the connection with clients as much as possible in order to make them feel like they’re not treated as a number but as individuals.

Justin Mensah


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. He always takes initiative so there is a pretty fair chance the task is already done before the client notices anything has to be done. Very easy to talk to.

Rob Herings

Xperience Management Trainer

Favorite saying: "Education is the most powerful weapon we can use to change the world". Rob is our tech & train sensei. He has trained both CEO's and Interns, in about every country you can imagine: South-Africa, India, Iceland, the USA, Japan, Australia, the United Arab Emirates. To name a few. He is what we call a real Globetrotter. Besides training, his true passion lies with outdoor climbing and exploring mountains.

Teresa Morins

Business Intelligence Specialist

Favorite saying: "Beauty may be dangerous but intelligence is lethal". Dexterous with data. Ingenious with climate science. Inventive when it comes to designing. When she is not constructing dashboards, she designs and fabricates her own furniture. To her, data reads like a novel: numbers are unknown and chaotic in the beginning but change into familiar characters once you figure out the story behind them.

Hester Kreuzen


Favorite saying: "There is no certainty, there is only adventure." A bachelor's degree in psychobiology. A master's degree in psychology. Specialized in brain and cognition. Safe to say that Hester is a sucker for everything concerning human behavior. Swings around to beats from the 2010's while being a female Sigmund Freud. Loves game nights with friends and long walks in nature.

Marsha Muller

Manager Marketing

Favorite saying: ‘’Don’t be intimidated by what you don’t know. That can be your greatest strength and ensure that you do things differently from anyone else.” Marsha is our sporty senior manager marketing mom with 15 years of experience in marketing. She is passionate about branding, User Xperience, digital innovation and IT. Marsha is a real social animal and can be found on her skis in Austria several times a year – including the après ski. Next to her love for skiing, she plays tennis and every weekend, you can find her supporting her kids during their hockey and football games.

She has a special gift, namely reading books very quickly. In addition to being creative and having a special gift, Karen values her family and friends.

Rumy Kanis

Head of Academy

Favorite saying: " Change is the end result of all true learning.” Rumy sets direction to all educational activities of the XLA Academy as the Head of Academy. She is strong willed, open minded and passionate about diversity and inclusion and she speaks 5 languages! Next to a true linguist, Rumy is a jack of all trades, she is a real family woman, a kitchen queen and she loves spending time in her garden cultivating her not-so-green fingers.

Tina Glasner

Senior Methodologist

Favorite saying: " If you don't like the road you're walking, start paving another one”. Tina is our analytical genius. Her skills are an excellent fit for her role as Senior Methodologist. She is a creative and quick thinker and is very solution oriented. Tina helps the research department with the further development of questionnaires and other research methods and plays a major role in the continuous improvement of Giarte’s quantitative and qualitative data analysis. Tina likes spending time with her friends and family. She also loves consuming culture: from theater to comedy, and from concerts to exhibitions.

Philippe te Wierik

Marketing & Communications Specialist

Favorite saying: "The artist must train not only his eye, but also his soul”. As our Marketing & Communications Specialist he is involved in various forms of media usage. Managing our social media channels, graphic design, copywriting, internal and external communication, he loves it all. Philippe is creative, adventurous and open-minded, which is reflected in his love for art, reading and mountains.

Tom de Gruijter


Favorite saying: "It’s a matter of perspective”. Tom is a real team-player and has a passion for efficiency, as such he is a perfect fit for his role as Researcher.

Adi Hargash

Learning Experience Designer

Favorite saying: " To truly know the world, look deeply within your own being; to truly know yourself, take real interest in the world”. In her role as Learning Experience Designer Adi is responsible for designing and improving our training courses and leading the user research for the XLA Academy. Adventurous and daring as she is, she loves to spend time camping and hiking with her family in nature. In the free time that is left Adi likes to get lost in reading, especially diaries and autobiographies.

Rob van der Schaaf

BI Specialist

Favorite saying: "Hoy llueve, pero mañana hay sol” (Today it rains, but tomorrow there is sun). He is honest, spontaneous and – as you may expect from his quote – has a passion for the Spanish language and shaking his hips. Rob is our dedicated Business Intelligence (BI) Specialist and responsible for account management, ETL processing and dashboard design. In his weekends he often heads into nature to go bird-watching or uses his exceptional logic skills to play chess.


Our Flow Houthavens building is designed to get you and your people into the flow state – that mental space where you do your best work. It’s a different kind of office. There are places to network, disconnect and reconnect.

Our building

There is a rooftop venue to host events as stimulating as the views; a laidback lobby lounge with a kitchen for guest chefs: for sharing cooking and entertaining experiences; and a backdrop of stunningly graphic LED walls.

The Flow state of mind

Daylight, outdoor decks, climate ceilings, and responsive intelligent systems add comfort. Unlike other office buildings, Flow understands that you need to relax to get the best results. Embrace the flow and watch your business flourish.
