Southern Arizona Tech + Business Expo 2026

The organizer reported more than 450 business and tech leaders.

It was held at Tucson Convention Center, Grand Ballroom, 260 S Church Ave, Tucson, AZ 85701.

Business and tech leaders from transportation, automation, optics, biotech, mining, aerospace, defense, and logistics were billed to attend.

It suited owners and business development staff at Southern Arizona firms in fields such as mining, aerospace, defense, optics and logistics, since the expo was a one-day regional show with 65+ regional companies and 450+ business attendees, so local contacts were the main return. Buyers or vendors seeking a national audience, or anyone outside the Tucson area, would find a much smaller pool than at a national trade show.

Attendees at a regional tech and business expo in Tucson usually wear business casual, such as slacks and a collared shirt or blouse, with a blazer for the awards and evening reception. Comfortable shoes help for time spent on a ballroom exhibit floor, and light layers suit an October day in southern Arizona.
