About me

Hi, I'm Christian Laesser, a freelance data visualization & UX designer based in Vorarlberg, Austria (DACH Region). For over 15 years I've helped large organisations, NGOs, and public institutions turn complex data into tools that support real decisions. My clients include WHO, Deutsche Bahn, Mozilla Foundation, and ACLED.

I work at the intersection of data integrity and user needs, pushing back when a visualization misleads and advocating for the people who ultimately have to act on what they see.

Increasingly, that means designing the user-facing layer of AI transparency: the interfaces, disclosures, and explanations that turn regulatory obligations like the EU AI Act into experiences that actually work for the people who rely on them.

More about my background

Services

I help organizations design clear, human-centered digital tools that make complex data accessible, from interactive dashboards to exploratory prototypes.

Service #1

Data Visualization

I turn complex data into clear visual narratives and interactive tools.

Whether for reporting, research, or internal strategy, I design visualizations that support insight and decision-making.

Service #2

Interface & UX Design

I create intuitive tools that help users navigate and understand complex information.

From policy platforms to public dashboards, I design interfaces that enable clarity, trust, and engagement across diverse audiences.

Service #3

AI Transparency Design

I design the user-facing layer of AI transparency, built for organizations navigating the EU AI Act.

This bridges the gap between data science and compliance teams and the decision-makers, boards, and users who need to understand, trust, and act on what AI systems produce.

    "Collaborating with Christian was a fantastic experience. He has a great ability to turn complex research and archival material into engaging data visualizations and digital storytelling. His prototypes provided clarity early in the process and helped shape the direction of the project with curiosity and creativity. Bringing theoretical and practical expertise into a productive dialogue is often difficult to achieve in interdisciplinary projects, which made this collaboration particularly rewarding."

    "Christian was an integral part of the project. He was able to build mock ups of any data source quickly. In a complex field of research and policy, this was exactly what we needed in the process. It gave us guidance to understand which data was insightful, and which aspects we wanted to highlight. The final data visuals are thoughtful, precise and have been shared widely across our networks. Christian is very professional, and I can highly recommend working with him!"
    — Katrin Fritsch, Senior Program Manager, Green Web Foundation
  • testimonial #5
    "Christian and Alice completely redesigned a number of tools we had previously developed in-house. With their skills, and Christian's conceptual development, we did not have to sacrifice on detail or depth, but instead could employ his wide range of talents to build some quite remarkable, interactive visualizations. "
    — Clionadh Raleigh, CEO, ACLED (Armed Conflict Location & Event Data)
  • testimonial #6
    "Working with Christian was a smooth process since the very beginning. He was always receptive to the data visualization design we were hoping to achieve, his expertise was instrumental to understand what was feasible and how our ideas could be improved. The communication channel was always open and the turnaround was usually faster than expected. We would be glad to collaborate with him again in the future."
    — Ariana Ocampo Cruz, Project Manager, International Coffee Organizations
