The vision and mission
One idea.
Joulo was built by two entrepreneurs with years of experience in fintech, compliance and software • both Tesla drivers. With the new ERE regulation we combine that expertise into a platform that automatically rewards home chargers.
// our story
Fintech DNA, built for the energy market.
Before Joulo existed, we built payment-gateway architecture, audit-compliance platforms and subscription systems at scale. That fintech experience is embedded in every part of Joulo: from automated NEa registration to the audit trail behind every charging session.
As Tesla drivers with Full Self-Driving, we know how great electric driving is. When we discovered that home charging generates emission credits, we saw the opportunity to combine fintech and energy into one platform that automatically rewards EV drivers.
// architecture
Built as
one system
Four layers that think, decide and execute together • without manual work.
01 · Connections
Joulo talks to 45+ charger brands. Connecting often takes a single click.
02 · Memory
Every session, every kWh, every price • remembered and organised.
03 · Brain
Automatically validate, calculate and pay out. No hassle.
04 · Insight
Your dashboard, app and exports • always up to date.
// founders background
Years of experience in fintech and compliance.
Johan has worked in energy and tech for years • from Solarplaza to Philips. Ruben has been building software and platforms for years with his company Capptions. Together we combine that experience in Joulo.
That background makes Joulo different: we understand how markets work, how to process data reliably and how to build a fair product that people trust.

// our approach
How we build
Three principles in the architecture of everything we make.
01 • Invisible
The best infrastructure goes unnoticed
Joulo works in the background • no manual work, no hassle. Registration, validation and payouts are fully automated.
02 • Fair
Every kWh is traceable
Every euro is accountable. Transparency is architecture: full audit trail with source, timestamp and mutations per session.
03 • Autonomy
The system runs itself
The system learns, validates and pays out. Without intervention, without delay. Built to scale without human bottlenecks.
