Voilà helps its clients to better understand and communicate their data. 


Information design is at the confluence of analysis and design. It means organizing information to convey clear meaning. Replacing complexity with clarity. Striving for elegance before aesthetics. Think of an enlightening graph, an illuminating report, or a transparent analysis.

We see a world of missed opportunities for shared understanding. We think we can help people understand and communicate better.

Where there is a report that overwhelms, we want to create one that enlightens. Where there is repeated failure to explain, we want to design a graph that convinces. Where there is a database that intimidates, we want to create a dashboard that clarifies.

Expect clarity before simplicity, elegance before aesthetics, purity before decoration. Expect curiosity and analysis.

Discover. Understand. Communicate. Convince.



Contact us for any work that implies the organization of information, from analysis and data visualization to reporting and design. Here are some examples of what we can do.

Francis Gagnon


Founder of Voilà, Francis Gagnon worked in reporting and information design at the international level for the last decade. He has clients in Washington, New York City, London, Tokyo, Beijing, Brussels and Montreal. At IFC, a member of the World Bank Group, he designed and produced six annual reports and tens of donor and management reports for their advisory services. For two years, he then lead a project to design and pilot new management reports for advisory services covering every management topic — finance, human resources, portfolio and results. Before that, he wrote reports and designed internal documents for the Centre for Applied Studies in International Negotiations (CASIN).

He studied data visualization with Edward Tufte, Hanspeter Pfister at the Harvard Extension School, Alberto Cairo at the Knight Center of the University of Texas, Jon Schwabish, Cole Nussbaumer and Andy Kirk. He attended Visualized, a conference in Manhattan on data, story and design in 2014, EyeO Festival in Minneapolis in 2018, and was invited in 2014 and 2017 to attend Tapestry, a conference limited to 100 people in the field of data storytelling. His work has been featured in "The best of the visualization web" by Visualising Data several times, and mentioned by The Economist and Fast Company. He was a speaker at Datavore 2019 and he's also one of the founders of Visualisation Montréal, a Meetup group with over 1700 members.

While at IFC, in Washington D.C., Francis worked to establish partnerships for the sustainable development of the private sector in emerging markets, raising over $50 million. In Geneva (Switzerland), he was in charge of international economics at CASIN, a training center for diplomats from developing countries. He also worked at the North American Forum on Integration in Montreal and the National Assembly in Québec City, Canada. He holds an M.A. in political science from Université Laval (Quebec City, Canada) and an M.Sc. in Development Studies from the London School of Economics (United Kingdom).

Francis is now based in Montreal, Canada, and is a member of the Québec Association of Economists.
