Cariqa is here to make EV charging work - faster, safer and completely transparent. We’ve built an omnichannel platform that gives Charge Point Operators total control: control pricing, get paid directly, and reach drivers however they want to pay. No markups. No middlemen. Just a transparent platform that helps clean transport scale. We’re not tweaking the old model. We’re replacing it.
We’re backed by leading investors in both climate and fintech - supporting our mission to bring direct, fair, and transparent payments to EV charging. We’re now actively growing our team. If you want to be part of this journey, apply now. And one day, when you plug in your EV and see a fair price at the charge point, you’ll know you helped make that happen.
