One of the most powerful commerce guilds in the Republic, the Techno Union is an organization made up of major technological manufacturers. Starship, computer, weapons and droid developers banded together under the leadership of the Union to further their own business ends.

The Foreman of the Techno Union was Wat Tambor. He allied the organization to the Confederacy of Independent Systems during the start of the Clone Wars, committing the Union's vast technological resources and droid armies to the cause of the Separatists.
