Ouster makes lidar sensors — devices that use lasers to generate 3D maps of a surrounding environment — and sells them to companies building autonomous machines and intelligent infrastructure. Ouster's core product is the OS sensor family, a line of scanning lidar sensors available in multiple configurations that trade off field of view versus range. These sensors are built on Ouster's proprietary custom silicon, which Ouster argues delivers high performance at lower cost than traditional analog lidar architectures. Beyond the OS line, Ouster sells two software-bundled products: Ouster Gemini, a perception platform for smart infrastructure applications like yard logistics and facility security, and Ouster BlueCity, a turnkey traffic management solution sold to cities and transportation departments. Both products bundle hardware and software into a single sale, and cannot be purchased separately. In early 2026, Ouster acquired Stereolabs, adding AI cameras and edge compute hardware to its portfolio, expanding Ouster beyond pure lidar into a broader sensing and perception platform. Ouster sells primarily direct to customers, though BlueCity relies heavily on regional exclusive distributors with established government relationships. Ouster's customer base spans four verticals: smart infrastructure, industrial, robotics, and automotive. Revenue scales with units shipped and average selling price, with gross margins improving as volumes increase, software-attached sales grow as a share of mix, and each new silicon generation improves performance without proportional cost increases.
