Brian Long is a co-founder and Managing Partner of Atlantic Bridge, based in Palo Alto, California. His Atlantic Bridge bio states that he has over 30 years of experience in the semiconductor and technology industry, that in 1993 he was founder and CEO of Parthus Technologies Plc, now CEVA Inc, that he led its 2000 dual Nasdaq and LSE initial public offering, and that in 2002 he founded and chaired GloNav Inc, sold to NXP in 2004. The bio states he has "served as a director on over twenty technology companies in Europe and the US" and names Movidius, DecaWave, Magnetics, Blue Data, Nanotec, Bridge Co, Silicon Blue, Lion Semiconductor, Hedvig Inc, Nod Labs, NuVia, Chirp and Navitas among those roles. Navitas Semiconductor's Form 10-K/A for the year ended 31 December 2025 lists him as a Class II Director whose term expires at the 2026 annual meeting, states he has been a Board member since 2015, and states he "is a founder and has served as Managing Partner of Atlantic Bridge Capital, a venture capital firm, since 2004". That filing is the only currently-confirmed board seat; the other named directorships relate to companies that have since been sold and are recorded as investments rather than as current seats. He started his career as a design engineer at Bell Labs AT&T and later led mixed signal IC design at Digital Equipment Corporation.
