// About Joulo

Built by fintech founders

The mission

Accelerating the transition to electric driving.

Everything we build serves that one sentence. Electric driving should be beautiful and easy. EREs are the start: automatic registration, every sale published and a 20% service fee with no small print. Then comes the rest of charging: sharing, smart charging, one charge card for the road and charging points that we operate.

The founders

Ruben Stolk (CTO) and Johan Trip (CEO) are neighbours and both drive electric. Johan previously built payment and subscription platforms, Ruben compliance software. Now they build Joulo together.

// Platform

Fintech infrastructure for emission credits

Joulo works like a payment platform: you connect once, then everything runs by itself. We read your charging sessions, register them with the NEa and pay out every quarter.

Direct connections

We connect your charger directly through the manufacturer's API. You never submit meter readings again.

Every kWh recorded

We record every kWh, check it and convert it into ERE credits. You see every step in your dashboard.

Sales and payouts

We sell the ERE credits every quarter via brokers and then pay out. Every sale is in our open sales ledger.

// Identity

What Joulo stands for

Transparency

20% service fee as standard, lower through loyalty and referrals. Always visible in your dashboard, no small print.

Automation

Connect your charger and forget Joulo exists • until money lands in your account every quarter.

Accessibility

Large companies have been earning from emission credits for years. Since 1 January 2026 every home charger can take part. You connect, we handle the rest.

Community

Joulo grows because customers refer new home chargers. Every active referral lowers your service fee by 1 percentage point, down to a floor of 10%.
