Physical AI Chipmaker SiMa.ai Hits $1.45B Valuation to Challenge Nvidia at the Edge

SiMa.ai secured $150 million in Series C financing at a $1.45 billion valuation to scale its embedded AI compute platform for robotics, drones, and autonomous vehicles. The capital will fund the development of Modalix, a next-generation system-on-chip targeting 1,000 tera operations per second (TOPS) by the first half of 2028. The startup is explicitly positioning its lower-power silicon and agentic development environment against Nvidia's high-end Jetson AGX Thor modules, which currently hit 2,000 TOPS but require power-heavy CUDA architecture. Fidelity Management & Research Company and Amplify co-led the investment, joining corporate backers like Dell Technologies Capital, Robert Bosch GmbH, and Synopsys Inc. "Physical AI in humanoids, automotive, and drones is the gateway to a $50 trillion market that has remained largely untouched by modern innovation. While others are still figuring out the pieces or repurposing their cloud offerings, we’ve built the entire puzzle." — Krishna Rangasayee
