Premium German OEM — mobile, AI, and connected-services platform
Conversational GenAI to 900K+ vehicles in six weeks
900K+ vehicles activated in 6 weeks
The challenge
The OEM committed to the first production conversational GenAI feature in its vehicles. The U.S. delivery path crossed app, cloud backend, vehicle, security, and legal — five-plus org boundaries that rarely move at the same speed. The launch window was weeks, not quarters, and there was no prior playbook for shipping production GenAI to a live fleet at this scale.
What Stephan did
Owned the U.S. delivery path end to end. Sequenced the cross-functional dependencies so app, backend, and vehicle teams stayed in lockstep. Stood up the GenAI operations and rollout controls needed to launch safely, and used feature-flag and entitlement infrastructure to gate activation and contain risk as volume ramped.
The outcome
900K+ vehicles activated in six weeks — the first OEM production conversational GenAI launch to reach the market. Delivered inside the window, with progressive rollout keeping risk controlled at fleet scale.
The numbers
- 900K+ vehicles activated in 6 weeks
- Zero rollback events
