Steradian Semiconductors

What Steradian Semiconductors does

Steradian Semiconductors Pvt. Ltd. is a fabless semiconductor company founded in 2016 and headquartered in Bangalore, India that developed CMOS millimeter-wave radar products for 4D imaging radar applications. The company's vertically integrated portfolio comprised three products: the SVR Radar IC — a fully integrated 16-channel E-band MIMO radar transceiver with 19 dBm transmit power, 8 dB noise figure, integrated 100 MSPS ADC, and a 14 Gbps data interface; the IRU Imaging Radar Unit — a 256-channel E-band MIMO radar module with 1.2° azimuth beam width, 120° azimuth field of view, and 15 fps refresh over Ethernet; and the IRS4D 4D Imaging Radar Software — a complete MIMO processing stack and visualizer achieving 0.1° azimuth and 0.3° elevation accuracy and compatible with Nvidia GPU compute platforms. Underlying technology is proprietary E-band CMOS MIMO radar developed by a leadership team composed predominantly of ex-Texas Instruments and Qualcomm RFIC engineers, with the CEO holding 40+ patents and products that previously shipped in volumes exceeding 1 billion units.

The company's commercial motion was enterprise field sales targeting automotive OEMs and Tier-1 suppliers for ADAS and autonomous-driving applications, with secondary targeting of smart mobility and intelligent transportation infrastructure use cases including traffic monitoring, urban driving scenario analysis, indoor sensing, and overbridge scenarios. Revenue was generated through hardware sales of the SVR IC and IRU module (with the IC ultimately distributed through Renesas/IDT post-acquisition) and through licensing of the IRS4D software stack. Pricing was not publicly disclosed; the website directed prospective customers to contact the company directly, consistent with a high-touch enterprise engagement model.

Following its acquisition by Renesas Electronics Corporation in October 2022 — under undisclosed financial terms — Steradian became a wholly-owned subsidiary of the Japanese automotive semiconductor leader, integrating its 4D imaging radar technology into Renesas' broader ADAS portfolio. Prior to acquisition, the company had raised approximately $2.1 million across a 2017 seed round, a 2018 Series A led by Endiya Partners, and a 2020 round led by Inflexor Ventures with participation from StartupXseed Ventures. Headcount at the time of acquisition was in the 51-100 range.
