How Mondu Scales with Real-Time Treasury from Atlar and Banking Circle

Mondu, one of Europe’s fastest-growing B2B payments providers, is working with Atlar and Banking Circle to run its treasury in real time as the business expands across six markets. Founded in 2021 and backed by more than $120 million in funding, Mondu needed a setup that could keep pace with rapid operational growth across multiple banks, entities, and jurisdictions.

Atlar and Banking Circle already support several joint customers across the fintech ecosystem. Mondu is a standout example of how the combination can provide finance teams with the clarity, speed, and reliability required to scale.

A modern treasury for a fast-moving fintech

As Mondu grew, its finance team needed accurate, real-time visibility across accounts and entities, faster payment cycles, and a more reliable data layer to support multi-market operations. Legacy processes and delays in accessing bank data made it harder to maintain control while keeping pace with the company’s growth.

“Real-time treasury is essential for any fintech operating across markets,” said Quiron Cunha, Chief Financial Officer at Mondu. “With Atlar we finally have all our accounts, all our data, and all our payments in one place. It’s transformed how we run finance.”

A unified setup built on Atlar and Banking Circle

Using Atlar, Mondu connects directly to Banking Circle through modern APIs and secure banking channels. Atlar’s connectivity is fully managed in-house on a proprietary platform, bringing bank connections, ERP integrations, and multi-entity workflows together without middleware or consulting projects. Because the connectivity layer is productized, implementation is significantly faster than traditional approaches.

This gives Mondu real-time access to balances, transactions, statements, and payment statuses while automated workflows replace manual touchpoints and reduce operational risk.

“For us, the implementation was smooth and well supported, and the platform is intuitive enough that our team could use it effectively from day one,” said George Hodorog, Head of Finance Operations at Mondu. “Atlar has significantly improved our cash visibility and allowed us to process payments much faster.”

The result is a setup that frees time, strengthens control, and helps Mondu unlock idle liquidity—without adding complexity as the business scales.

Delivering clarity and speed for modern finance teams

“Atlar helps finance teams work in real time without the delays or manual work they’re used to,” said Joel Nordström, Co-founder and CEO of Atlar. “Mondu is a great example of a company that moves quickly and expects the same from its financial tools. Together with Banking Circle, we’re giving them a setup designed for speed, clarity, and scale.”

Banking Circle is a fully licensed bank headquartered in Luxembourg, providing customers with direct access to several major payments schemes and 24 currencies, with exciting expansion plans in many more jurisdictions. By combining robust and modern API technology with the resilience of a regulated bank, Banking Circle enables finance teams like Mondu’s to move funds quickly, streamline cross-border payments, and operate with greater certainty at scale.

Recently named World’s Best Challenger for Cash Management by Euromoney, Banking Circle continues to expand its real-time capabilities for financial institutions. Charlotte Schiøttz Hassing, Head of Payments and Business Development, said: “Our mission is to remove friction from cross-border banking. Working with Atlar enables companies like Mondu to access reliable, real-time data and payment flows as they grow.”

With Atlar and Banking Circle, Mondu now operates with real-time visibility across accounts, faster payment cycles, and a more scalable treasury foundation for the next phase of growth.
