About Joulo

    Two entrepreneurs. One idea.

    Joulo was founded by two neighbours from Brummen • both entrepreneurs, both Tesla drivers. We saw that the new ERE regulation offers opportunities for home chargers and decided to do something about it.

    // our story

    We're obsessed with electric driving.

    We both drive Tesla, with Full Self-Driving. Every day we enjoy how great electric driving is • and we want more people to make the switch.

    When we discovered that home charging generates emission credits, we saw an opportunity: a platform that automatically rewards EV drivers. Lowering your charging costs and making the switch to electric even more logical.

    // our approach

    How we build

    Three principles in the architecture of everything we make.

    01Invisible

    The best infrastructure goes unnoticed

    Joulo works in the background — no manual work, no hassle. Registration, validation and payouts are fully automated.

    02Fair

    Every kWh is traceable

    Every euro is accountable. Transparency isn't a feature, it's the architecture. Full audit trail, always accessible.

    03Autonomy

    The system runs itself

    The system learns, validates and pays out. Without intervention, without delay. Built to scale without human bottlenecks.
