Swap,
don’t rent.
A car waiting for you on the other side of the country.
Two travelers heading opposite directions. Two cars sitting at two airports. Siffna matches them — so each one drives off in a stranger’s car instead of paying $90 a day to Hertz.
Three steps. No counter, no surge.
Most people don’t realize how often two trips line up perfectly — your car is sitting at LaGuardia for the same week mine is sitting at LAX. Siffna finds those pairs and brokers the swap.
Tell us your trip
Where you’re flying from, where you’re landing, and the dates your car will be parked at the airport.
We match the swap
Siffna pairs you with a verified traveler going the opposite direction. Both cars get inspected, insured, and listed for the matched window.
Keys at the airport
Pick up your match’s keys at the airport lockbox when you land. Drop them off when you fly home. Your car is back in your driveway when you are.
From plan to pickup, in your pocket.
Siffna lives on your phone. Plan a swap in the morning, get matched by lunch, walk off your flight to a car already waiting for you.

Every kind of car. Every kind of trip.
Sedans for solo travelers. SUVs for families. Trucks for moving day. The Siffna fleet is whatever your neighbors drive.
“The car is the second most expensive thing most Americans own, and it sits idle 95% of the time. Siffna is what you get when you finally let it work for you.”— The Siffna thesis
Cheaper than renting. Better than parking.
Renting a car at your destination and parking yours at the airport are two ways of paying for the same week of driving. Siffna replaces both with one trade.
Cheaper than renting
The average swap saves $487 over a week of renting, because nobody is charging you a daily counter rate. You pay one flat inspection + insurance fee.
No idle car at home
Your car would have sat at the airport burning $35/day in long-term parking. Instead it earns its keep driving someone else around your city.
Skip the rental counter
No upsell, no “did you decline collision?”, no shuttle bus to off-airport lot 7. Walk off the plane straight to your match’s car.
Real humans, both ways
Both drivers pass background + license checks. Both cars get inspected the day before. Insurance covers everything in between.
A stranger’s car, without the strangeness.
The whole thing only works if you’d genuinely hand your keys to your match — and they’d hand theirs to you. So we built the trust layer first.
Covered end-to-end
Every swap is underwritten by our insurance partner. Liability, collision, comprehensive — bundled into the inspection fee. No deductible surprises.
28-point pre-trip check
Both cars stop at a Siffna-certified shop the day before the swap. Mileage, fuel, tires, photos — all on record before keys change hands.
Drivers we’d trust ourselves
License + background + driving history check on every member. Anyone who can’t pass the bar we’d set for our own car doesn’t get matched.
