Launching at UC Berkeley
ride together. split the cost.
A student is already driving where you're going. tag. finds them, you tag along, and the real cost of gas splits between everyone in the car.
One Saturday trip
Jordan was already driving from Berkeley to Tahoe on Saturday. He posts the trip on tag.
Maya needed a ride the same morning. tag. matched her with Jordan's trip, and the gas now splits two ways.
Sam tags along too. Nobody renegotiates anything. Another seat fills and everyone's share just drops.
Leo takes the last seat. Four people, one car, the same drive that was happening anyway.
Everyone gets there. Riders paid a fraction of driving alone, Jordan's gas is covered, and nobody profited.
Each person pays
$9.90
3 riders · car full
Example trip: about 180 miles, a 30 MPG car, gas at $5.85 a gallon, and tag.'s flat $1.50 rider fee. Real prices are computed live for every trip.
The idea
Ride pairing, not ridesharing.
A student who is already driving somewhere fills their empty seats. Riders split the real cost of getting there. Nobody drives for money.
What tag. is
Students sharing a drive.
- ✓ A driver posts a trip they were already taking.
- ✓ Riders tag along and split the real gas cost.
- ✓ The price drops as more seats fill.
- ✓ Everyone is a verified .edu student.
What tag. is not
Not Uber. Not a gig.
- · Not a taxi or ride-hail service.
- · Drivers don't earn fares or make a profit.
- · No meters, no surge, no strangers off the street.
- · Cost-sharing between students. That's all.
How it works
Three steps. Both sides can start.
Post a trip, or ask for a ride
Driving somewhere? Post the trip you were making anyway. Need a ride? Post a request with a rough window, like Friday afternoon.
Get matched
tag.'s matching engine pairs trips with requests going the same way. Riders ask to join, drivers approve, and the plan comes together.
Split the real cost
Gas is computed from the actual route, the car's EPA mileage, and today's gas price, then divided by everyone in the car. You see it before you commit.
The split
You see every cent, every time.
No surge, no hidden margins, no guesswork. Your share is the gas, divided by the people in the car, plus a flat $1.50 platform fee. That fee is the only money tag. makes.
Friday, 3:30 PM · Alex's Honda Civic
Drops to $6.75 each if every seat fills.
The app
Native iOS, built like it belongs there.
Trust
Students only. Verified, every one.
Everyone on tag. confirmed a real college email before they could post or join anything. You're sharing a car with people from campus, not the open internet.
.edu verified
A valid, confirmed college email is required to sign up. No email, no account.
Real profiles and ratings
Names, photos, cars, and ratings after every completed ride. You know who you're riding with before you tap join.
One campus at a time
tag. launches campus by campus, starting at UC Berkeley, so the network stays close to home.
