Olivier and Simon met while working together in a small company in Norway called Trolltech, on the Qt C++ toolkit. Here, they gained valuable experience in API design, cross-platform software development and user interface components.

Simon continued in the Qt Company as a lead developer and maintainer of the QtQml engine, while Olivier co-founded Woboq, a software consulting company.

Years later, in 2020, they started the SixtyFPS project and company in Berlin. The SixtyFPS project has been renamed to Slint, and the company has been growing.
