Faststream Technologies Tech Stack

5G and space-enabled wireless semiconductors for private networks

Semiconductor Manufacturing Los Angeles, California 51–200 employees Founded 2010 Privately Held

Faststream designs custom semiconductors and RF solutions for private 5G networks, with particular focus on space-enabled and terrestrial radio access. The tech stack—FPGA, ASIC, 3GPP, Satcom, Rust, WebRTC, and mixed-signal design tooling—reflects a hardware-to-systems integration play. Active projects span OpenRAN radio units, DPD subsystems, AI inference chips, and decentralized networking, signaling a pivot toward AI-on-silicon alongside traditional connectivity. Leadership-heavy hiring (principal, director, VP roles) combined with tight funding constraints suggests they're positioning for a Series A or customer-anchored growth phase.
