Ambarella Acquires Oculii for $307.5 M, Expanding Radar & Sensor Fusion for Autonomous Vehicles

Ambarella has announced the acquisition of Oculii Corporation for $307.5 million, positioning the company to broaden its offerings into radar perception and sensor fusion—critical technologies for next‑generation automotive AI.

Founded in 2013 and headquartered in Dayton, Ohio, Oculii has pioneered adaptive AI software that transforms standard production radar chips into high‑resolution sensors. By dynamically adjusting waveform parameters, Oculii’s algorithms deliver up to 100‑fold higher resolution, extend detection ranges to 400 meters, and enhance accuracy—all while keeping power consumption and cost comparable to conventional radar.

These capabilities unlock new possibilities across the automotive spectrum, from advanced driver‑assist systems (ADAS) to fully autonomous vehicles, robotics, and security solutions. The technology enables an all‑weather, wide field‑of‑view perception platform that can be integrated with existing radar RF modules.

Oculii is already in partnership with 10 of the top 15 automotive tier‑1 suppliers and has secured commercial development agreements with leading OEMs and AV firms. The company has begun generating pre‑production revenue and is slated to launch production programs in CY2023. Notably, General Motors invested “millions” in September 2023, and Oculii previously raised $55 million in May 2021. It also maintains collaborations with Geely and Great Wall Motors in China.

Oculii’s software is fully compatible with Ambarella’s CVflow SoCs, allowing seamless integration of radar data with the company’s established vision AI stack. This synergy enhances safety and reliability for automotive, mobile robotics, and security endpoints.

In the acquisition announcement, Ambarella highlighted how the deal expands its addressable market beyond vision AI to encompass radar perception and sensor fusion. The combination of Ambarella’s camera technology and Oculii’s radar software stack delivers a low‑cost, scalable solution that supports higher autonomy levels for automotive tier‑1s and OEMs worldwide.

Fermi Wang, President and CEO of Ambarella, said, “The Oculii team brings exceptional synergies to our algorithm‑first approach and our edge AI initiatives. Their adaptive radar perception will unlock new levels of accuracy when combined with our vision and AI processing.” He added that future Ambarella SoCs will feature increased processing power for video‑and‑radar fusion.

Steven Hong, CEO of Oculii, noted, “Joining Ambarella accelerates our radar technology development and leverages the strengths of a leading vision and AI processor company.”
