Cities depend on data to design safer roads, protect vulnerable road users, and prioritize infrastructure investments. Yet the tools used to study roadway safety have changed little in decades. Engineers still rely on temporary sensors, manual traffic counts, and hours of video review to understand what happens on the street.

Cumulant was founded to modernize this process.

Our platform transforms roadway infrastructure into a continuous source of scaling safety intelligence - automatically collecting and interpreting real-world traffic behavior directly from the street.
