SiMa.ai, a startup developing chips and software that let robots, drones, cameras and other devices run AI locally, has raised $150 million in Series C funding at a $1.45 billion valuation. The round was co-led by Fidelity Management & Research Company and Amplify, with participation from Alter Venture Partners, Dell Technologies Capital and StepStone Group.

Founded in 2018 by Krishna Rangasayee, former COO of chipmaker Groq, the company offers energy-efficient chips designed to reduce reliance on cloud data transfers. SiMa.ai aims to tap the growing physical AI device market, including humanoid robots, with lower-latency and more affordable alternatives to Nvidia GPUs.
