PHOENIX, Ariz. – Guy Galanti, 48, an Israeli citizen who resided in Scottsdale, Arizona, was sentenced yesterday to time served with three years of supervised release by United States District Judge G. Murray Snow. Galanti was previously charged for Conspiring to Steal a Trade Secret on September 10, 2025, and was arrested the following day. Galanti has been in custody since his arrest. He pleaded guilty to Conspiring to Steal a Trade Secret on May 26, 2026.
Galanti worked as a senior level manager for Green Technology Investments (GTI) in Scottsdale, Arizona. GTI is based in Arizona and is in the business of servicing semiconductor testing machines and selling remanufactured semiconductor testing machines with new functionalities designed by GTI.
Beginning sometime in early January 2025, and continuing to August 2025, Galanti conspired with another individual to steal GTI’s newly created Glass Detect Design, which would allow a semiconductor testing machine to locate microscopic defects on a semiconductor wafer made of glass instead of silicon material. Galanti’s co-conspirator sought to recreate GTI’s new design as he operated a Taiwanese company that directly competed with GTI.
Over the course of several months, Galanti secretly sent photos of GTI’s Glass Detect Design, information, and software, to his co-conspirator in an effort to recreate GTI’s proprietary system. To conceal their interactions, Galanti and his co-conspirator communicated over an encrypted messaging system, deleted emails and transaction data sent from Galanti’s work email, and created fictitious invoices to document the transfer and potential payment of funds to Galanti.
The FBI’s Phoenix Division conducted the investigation in this case. Assistant U.S. Attorneys Raymond K. Woo and Matthew Williams, District of Arizona, Phoenix, handled the prosecution.
