More than a company. More than a project. More than a dream.
We are the living result of two generations that transformed purpose into action — a journey born from vision, perseverance, and conviction.
As the flagship brand of SIOUX LLC, AUROBORO embodies the union between consciousness and commerce — where Clean Production and Fair Trade are not slogans, but principles that shape every decision we make.
We believe in the invisible thread that connects origin and destiny — the responsibility of returning to the earth with the same integrity with which we extract from it.
