SiMa.ai was founded in 2018 by Krishna Rangasayee, who was previously the COO of chipmaker Groq. The company provides energy-efficient chips that eliminate the need to send data back and forth to the cloud. It aims to serve physical AI devices, a category that includes humanoid robots.

SiMa.ai hopes its low-latency performance and more affordable chips, compared with Nvidia's GPUs, will help it capture the growing market for physical AI devices. TechCrunch reported that the market includes humanoid robots.

The new round brings SiMa.ai's total capital raised to more than $500 million. PitchBook data cited by TechCrunch show SiMa.ai was previously valued at $960 million after raising an $85 million Series B in July 2025. The Series C values the startup at $1.45 billion.
