Cumulant builds AI operators for the physical world. Starting with safer streets and smarter transportation.

Measure what actually happens on the road, from the road. Cumulant turns existing camera infrastructure into direct observations, high-resolution behavior data, and reviewable evidence.

Safety decisions should begin with what actually happened.

Cities already have cameras and continuous video. Cumulant makes that infrastructure useful by interpreting movement, interaction, and risk while keeping every finding connected to its source.

Ground-truth measurements

Lane-level trajectories, speeds, and multimodal interactions provide the spatial and temporal detail required for modern safety analysis.

Transparent and verifiable

Every insight remains connected to observable events and source evidence, so teams can review, validate, and defend the decisions that follow.

Build AI that has to work in the real world.

Our team connects vision AI, edge systems, product design, and field operations. Strong ideas still have to survive cameras, connectivity, policy, review, and daily use.
