The back of a pickup is the most-read blank space in the city.

Pickups drive the busiest roads in Los Angeles every day, and the car behind is looking straight at the tailgate. Most of them carry nothing.

We built Tailgate to change that, with one rule: an advertiser should be able to check every impression they pay for. So every sign carries a beacon, every truck carries a tracker, and every number in a report traces back to public traffic data.

Drivers get paid fairly for miles they were already driving. Anyone can also buy a sign for their own truck.
