indie Semiconductor designs and sells mixed-signal semiconductors and software for automotive applications, with a primary focus on ADAS. indie is fabless — it outsources manufacturing to foundry partners like TSMC and GlobalFoundries — and sells its chips to Tier 1 automotive suppliers like Bosch and Valeo, who integrate indie's chips into modules installed in vehicles by OEMs. indie's core product portfolio spans the key sensing modalities used in ADAS: a 77 GHz chipset for radar (object detection, automatic emergency braking, blind spot detection), and the iND880 image signal processor for camera monitoring systems, e-mirrors, and driver and occupant monitoring systems. indie also sells in-cabin user experience chips covering wireless charging, USB power delivery, and in-car connectivity, though indie is actively de-emphasizing these lower-margin products in favor of ADAS. indie's business model is volume-driven — revenue scales with chips shipped, which is tied to vehicle production and chips per vehicle. Automotive semiconductor design cycles are long, with design wins typically 3–5 years before production begins. indie acquired emotion3D in 2025, adding AI-based in-cabin perception software that introduces a software royalty stream alongside hardware sales. indie also operates a small Photonics unit making laser components for LiDAR and quantum communications. indie is divesting its 34% stake in Wuxi indie Micro, a Chinese subsidiary that represented roughly 43% of FY25 revenue but carried below-average gross margins.
