Built by a Veteran
Robert Joseph
Built by a veteran mechanic, for every driver

I built Know Your Ride because I got tired of watching people get overcharged for information that should be free. After years working on everything from diesel generators and agricultural equipment to military fuel systems and high-voltage electric vehicles, I know what it takes to keep machines running. Every spec in this app is the same data the pros use — now it's yours.

  • US Military Veteran
  • Professional EV diagnostics technician (high-voltage electric vehicles)
  • Diesel engine and heavy equipment experience
  • Off-road and agricultural equipment expertise
  • Military fuel systems — helicopter refueling operations
  • Years of hands-on experience across gas, diesel, and electric powertrains
