The Opportunity

Problem

Solo founders lack CAN bus expertise required to develop connected car features, blocking their product progress.

Solution

Get instant REST APIs for common features like diagnostics, telemetry, geofencing using our CAN gateways. Solo founders connect in 5 mins via keys, scale with usage. Focus on your app, we handle CAN parsing and vehicle compatibility.
