carpool and get paid for the energy you save.
share a ride with people you know. eligible shared journeys can be certified through Spain's energy savings certificate (CAE) programme, and you receive your share through sparkies.
how it works
share your car
record your shared journeys in naiss with the people who travelled with you.
we certify it
that energy saving is measured and officially certified as a CAE. companies obligated to save energy buy them.
you get paid
your share is recorded as sparkies. the app shows their status and when a payout is available.
why you earn more with naiss
for the same certified energy savings, you take home around 60% more.

other apps
sharing has value. we return most of what we receive for certified energy savings and use a share to keep the app, servers and team running.
why we don't promise you a fixed amount
a fixed number sounds nicer, we know, but promising it doesn't make the saving real: it depends on the price the certificates sell for and on them being officially certified. so we count your share in sparkies and pay you your real share of the pot, no inflated numbers, no fine print.
so what are sparkies?
- eligible shared journeys earn sparkies for the driver and passengers.
- your wallet shows confirmed sparkies, pending steps and available payouts.
- check your own balance and payout details in the app.
the important bits, no fluff
- it's real and regulated (Royal Decree 36/2023). that's why it takes time: certifying the savings is an official process.
- to take part you must be over 18 and verify your identity (DNI/NIE). the anti-fraud rules require it.
- payment depends on the savings being validated. if a trip isn't validated, it can't be paid.
- we tell you exactly what data we process and how in the privacy policy and the terms and conditions.
