How Roam Energy increased charge sessions by 100% in five months with Monta

The Challenge: Growing Fast Without the Right Software

Roam Energy was built on a simple idea: make EV charging profitable, reliable, and easy to use, not just for drivers. The co-founders had built hundreds of EV sites and had seen firsthand where the process broke down: complicated software stacks, poor data visibility, unstable hardware, and zero accountability when things went wrong.

They built Roam to avoid those issues. They chose site locations carefully and designed stations people actually wanted to use. But finding the right software was proving difficult. They tested nearly every major platform, but none offered the visibility, flexibility, or support they needed to scale.

As Roam grew, problems mounted:

• No central performance view
• Driver support calls went straight to the founders
• Payment terminals often failed
• Financial data was scattered and delayed

Roam didn’t need another workaround. They needed one system to bring everything together. That’s when they found Monta.

The Solution: A Software Built for Professional Operators

Monta understood exactly what Roam needed: operational clarity, real-time diagnostics, and scalable support. Roam migrated their charging portfolio to Monta, upgrading their entire operation:

• Centralized charger management with deep visibility into OCPP messaging
• Real-time health and connectivity monitoring with alerts and live data
• OTA firmware updates and remote troubleshooting reducing field visits
• Reliable, cloud-connected payment terminals, stabilized by Monta's integrations
• Integrated driver support through Monta’s 24/7 team
• Automated revenue routing via Monta Wallet with full transaction visibility
• OCPI interoperability for seamless roaming across networks
• Advanced reporting and analytics for ROI and performance tracking
• Collaborative product development through a direct operator-to-Monta feedback loop

The impact was immediate. Roam gained live visibility into failures, connectivity, and OCPP-level data. Instead of juggling spreadsheets and field calls, they could detect and fix issues before drivers were affected. Monta’s support team took over driver communication. For the first time in months, the founders slept through the night.

With support off their shoulders and software filtering only urgent alerts, Roam could trust that drivers were covered and chargers stayed online. Financial reporting also improved. Roam could now segment performance by site, charger type, or capital partner. Revenue was routed automatically, no spreadsheets required.

With Monta powering their operations, Roam stayed lean but scaled faster. They used Monta to:

• Monitor and limit peak demand, reducing energy costs
• Set load limits based on real-time and historical data
• Launch new sites quickly and consistently
• Avoid unnecessary fieldwork
• Benchmark hardware performance
• Access earnings and site performance instantly through Monta Wallet
• Deliver a premium driver experience at scale

The Results: A Stronger Business and a Better Driver Experience

With Monta’s cloud integration, terminal performance stabilized, and combined with the QR/NFC easy pay option, driver experience improved and PlugShare scores began to climb. Drivers were charging more consistently, support calls were reduced, and Roam avoided expensive hardware swaps.

These improvements eased operations and fueled growth. Within five months of switching to Monta, Roam saw a 110% jump in kWh charged and a 100% rise in charge sessions. “We’re starting to see some really interesting trends in recurring use,” says Joe.

Utilization improved month over month. Joe credits the momentum to Monta’s platform stability and simple OCPI integrations, which boosted visibility and usage without requiring him to build roaming partnerships himself.

In just 5 months, Roam achieved:

• 110% increase in kWh charged
• 100% increase in charge sessions
• Fewer support calls waking the founders
• Higher charger uptime and success rates, with failed sessions cut in half
• More stable payment terminals across locations
• Smooth, consistent revenue reconciliation
• Higher PlugShare ratings and fewer driver complaints
• Scalable growth with a lean team of under 10 employees

By switching to Monta, Roam eliminated the friction holding them back and gained a true operating advantage. They now scale faster, stay lean, and turn more sessions into revenue without adding overhead.

The Vision: A Smarter Way to Scale Charging

Roam sees Monta as part of their team, offering hands-on engineering support, clear roadmap visibility, and a dedicated US-based Customer Success Manager who meets with them regularly. Even Monta’s CEO has joined troubleshooting calls to help solve urgent issues. With Monta, Roam no longer needs DevOps or custom tools to grow. They operate like a larger company without increasing headcount.

Roam is building the kind of CPO others aspire to be: lean, focused, and grounded in real-world results. Their growth is measured by chargers in the ground, not headlines.

Monta shares that mindset. From software updates to proactive support, the partnership is built on shared goals. As Joe said, “When you say ‘Our problem is your problem,’ we believe it. And we know it to be true.”

Monta is in the US for the long term. Our work with Roam reflects our mission: to help CPOs scale faster, smarter, and more sustainably. For Roam and others like them, Monta is more than a vendor. We are a true infrastructure partner.

Customer Testimonial

“Prior to migrating everything to Monta, we didn't have a good understanding of what our problems really were. We knew we had some weird behaviors. We knew we had some inconsistencies in driver experience, but we didn't have enough data to understand what those issues were. So when we moved everything to Monta, we very quickly became acutely aware of the pain points for the driver and the inconsistencies in the driver experience and leveraging the data that Monta makes available at our fingertips.”
