Founder story
Founded in 2015 by Karel Callens, Haroen Vermylen, and Thomas De Clerck in Leuven, Belgium. The founders, who previously ran a data consultancy, realized that building custom dashboards for SaaS apps was a 'nightmare' for developers. They built Luzmo to be the 'Lego-block' of analytics for the modern web.
