Obvio, a San Carlos-based startup, has raised $22 million in a Series A funding round led by Bain Capital Ventures to expand its AI-powered stop sign camera technology. The system uses bright orange, solar-powered pylons equipped with cameras at intersections to detect and record serious traffic violations, including running stop signs, speeding, crosswalk violations, illegal turns, unsafe lane changes, and distracted driving. The cameras process footage locally, retaining non-violation footage for only 12 hours before deletion. Only clips of actual violations are uploaded for human review before being sent to law enforcement, and municipalities retain ownership and access to the data. Obvio's technology is already operational in five cities in Maryland, with plans for further expansion. The company reports a 50% reduction in stop sign running within eight weeks of deployment. Obvio provides its technology to municipalities at no upfront cost, generating revenue through a share of citation fees, with the split varying by jurisdiction. Co-founders Ali Rehan and Dhruv Maheshwari emphasize balancing safety, privacy, and community advocacy, focusing on targeting the most dangerous driving behaviors rather than minor infractions.
