Pauls started his career on television as a host of a videoclip show before starring in the teen soap opera Montaña Rusa.

But it was his participation in the memorable Nine Queens by Fabián Bielinsky alongside Ricardo Darín and Leticia Brédice that gave him international recognition and the award for best actor in Biarritz.

Then in 2003 he decided to return to television in the scripted Tres padres solteros and the show Ser Urbano a mix of fiction, journalism, and factual documentary broadcast until 2006 by Telefe.

In 2005 Pauls founded with Alejandro Suaya a production company called Rosstoc S.A., in which he surrounded himself with a dynamic team of quality professionals and with which he created programs such as "Mejor hablar de ciertas cosas", "Todos contra Juan" and "Ciega a citas".

From 2007 to 2014, Pauls was in a relationship with fellow Argentine actress Agustina Cherri,[1] with whom he had two children, daughter Muna (2009) and son Nilo (2011).
