// About us
Who we are
Hola Mundo LLC operates the communities, events and media that connect Spanish-speaking technology professionals across Latin America, Spain and beyond. What started in Buenos Aires in 2012 as a gathering of systems administrators has grown into a network of communities, conferences, podcasts and educational initiatives reaching hundreds of thousands of people every year.
Our mission is simple: make high-quality technical knowledge accessible to everyone, in Spanish, for free. We do it by supporting the people who keep the internet running — engineers, sysadmins, SREs, developers, security specialists and data professionals — and by producing events where they can learn, share and meet each other.
