Alejo Rébora was born in June 1985, in Buenos Aires.

He founded SARNA in 2003 to distribute his initial, cheap, and small short films as a filmmaker. Later, he studied film direction; the shorts began to be less modest, and SARNA's technical team expanded to become a natural force advocating CINEPUNK with much more imagination than budget.

From 2007 to 2018, he managed, conceptualized, did graphic design, and authored DVDs for Distribución SRN, a label that champions "underground cinema in deluxe editions" title by title.

Currently, he has five feature films in his filmography —the TRASH trilogy (2010-2019), the documentary El Camino de Tico Tico (2020), and the suspense comedy 7 VIDAS (2024).

SARNA continues to produce and create short films, music videos, and independent and somewhat experimental films.
