# WS-Dev Kft. > WS-Dev Kft. is an independent software company in Budapest, Hungary, founded in 2009. It builds enterprise systems for public administration and for private companies, and is the developer of SchemaVortex, a governed data lakehouse platform. Its motto since 2009 is "We DO build software". The company's claim is longevity rather than volume: several of its systems went into production and stayed there for a decade or more, long after the projects that paid for them ended. ## Key facts - Legal entity: WS-Dev Informatikai Szolgáltató Korlátolt Felelősségű Társaság, trading as WS-Dev Kft.
