// About Joulo

Built by fintech founders

The mission

The ERE market is a financial instrument • and deserves the same fintech approach as the payments market. Joulo was founded on the conviction that transparency, automation and fair pricing should be the standard, not the exception.

The founders

Ruben Stolk (CTO) and Johan Trip (CEO) are neighbours, EV drivers and former fintech builders. They combine years of experience in API platforms, data infrastructure and payment systems to build Joulo.

// Platform

Fintech infrastructure for emission credits

Joulo is not an app • it is infrastructure. Built on the same principles as modern payment systems: API-first, real-time processing and payment-grade payouts.

API-first

Direct connections to chargers through manufacturer APIs. Never submit meter readings by hand again.

Ledger system

Every kWh is recorded, verified and converted into ERE credits. Transparent and auditable.

Market optimisation

Selling credits at the optimal moment. Payment-grade payouts every quarter.

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

Emission credits are not a privilege of large companies. Every EV driver with a home charger is entitled to their share.

Community

Joulo grows by sharing. The more home chargers take part, the more efficient ERE registration becomes. We give that benefit back through referrals: users help each other to lower service fees, without complicated campaigns.
