SiMa.ai, a startup developing chips and software for physical AI systems such as robots and drones, has raised $150 million in a Series C funding round at a $1.45 billion valuation.

Fidelity Management & Research Company and Amplify co-led the round, SiMa.ai said Monday. Existing investors Alter Venture Partners, Dell Technologies Capital, Maverick Capital, +ND Capital, Point72 and StepStone Group also participated.

AllianceBernstein, Baron Capital, JPMorgan and the State of Michigan joined as new investors. The Series C brings SiMa.ai's total funding to $500 million, according to the startup.

Before the latest round, SiMa.ai said it had raised $355 million as of August 2025, including an $85 million round that month and a $70 million round in 2024. Earlier rounds included a $67 million Series B1 in 2022, an $80 million Series B in 2021, and a $30 million Series A in 2020. Semiconductor manufacturing company Micron Technology also made an undisclosed strategic investment in SiMa.ai in April of this year.

What is SiMa.ai?

SiMa.ai develops chips and software for AI applications in robots, vehicles, drones, industrial equipment, aerospace and defense systems, smart cameras and healthcare devices.

"While Physical AI has historically relied on expensive, complex, and power-hungry NVIDIA GPUs, SiMa.ai delivers the industry’s leading full-stack Physical AI platform combining purpose-built silicon and software to streamline deployments from months to days or hours," the startup claimed.

SiMa.ai said its revenue grew fourfold between 2024 and 2025 and continued to increase in 2026, though it did not disclose figures. Its customers and partners include Bosch, Emerson, Micron, Synopsys, TRUMPF and L&T Technology Services.

"Physical AI in humanoids, automotive, and drones is the gateway to a $50 trillion market that has remained largely untouched by modern innovation," said SiMa.ai founder and CEO Krishna Rangasayee, a former chief operating officer at Groq, an AI chip company focused on running AI models. "This investment will further catapult us into a dominant position, giving us the resources to scale our purpose-built platform."

SiMa.ai said it will use the funding to expand Palette Neat, its software environment for developing and deploying AI applications on physical machines.

The startup will also develop its next generation of hardware, planned for the first half of 2028. The products will include machine-learning intellectual property, chiplets and complete systems-on-a-chip.

SiMa.ai said the new hardware will provide 1,000 dense TOPS (trillions of operations per second) of computing performance. TOPS measures how many trillion operations a processor can complete each second.

The technology is being developed for medium- and high-end drones, humanoid robots, driver-assistance systems, and AI features inside vehicles and cockpits, according to SiMa.ai.
