Sagi has been a serial entrepreneur since he was nine years old. But instead of printing and selling stickers, he creates, scales, and optimizes SaaS solutions. Before he established Perimeter 81—and SaferVPN with Amit—he worked as a UX consultant for Siemens. Today, Sagi leads all of Perimeter 81’s demand generation, marketing, and design. During his army service, he worked in the IDF’s elite visual intelligence unit and later was a software developer at Imperva. He has a patent for the security of public Wi-Fi networks and received a B.Sc. in Computer Science and Economics from Tel Aviv University.
