Pleo ⎯ Finance Management Platform - United Kingdom

Development

project

Introduction

Bloomteq engineers are working closely with Pleo's team to build robust integrations with banks and third-party financial institutions. The goal is to enhance the Pleo platform with new features like multi-currency wallets, automated money movements, expanded international support, and external account management - all within the Pleo app.

Challenge and Scope

Pleo needed to expand its platform capabilities to stay competitive in the rapidly evolving FinTech landscape. Key challenges included:

  • Integrating with a wide range of third-party financial institutions and bank APIs.

  • Enabling Open Banking features to meet regulatory requirements such as PSD2.

  • Building reliable multi-currency wallet functionality with automated money movement.

  • Extending international support while maintaining seamless user experience inside the Pleo app.

  • Managing external accounts securely within a single, unified platform.

Approach, Solution and Outcome

Approach

Bloomteq's engineers collaborated directly with Pleo's integrations team to assess the technical landscape and identify the fastest path to delivering value. The team focused on:

  • Deep-dive analysis of existing bank API connectivity and gap identification.

  • Designing event-driven architecture for payment notifications and ledger updates.

  • Defining a phased roadmap for Open Banking feature delivery.

Solution

  • Built robust integrations with banks and third-party financial institutions using Kotlin and PostgreSQL.

  • Implemented multi-currency wallet infrastructure with automated money movement flows.

  • Developed external account management features available natively within the Pleo app.

  • Leveraged Kubernetes on AWS for scalable, high-availability deployment with Grafana for observability.

  • Integrated with Open Banking APIs and various bank connectors to expand Pleo's international reach.

Outcome

  • Pleo customers gained access to expanded international banking support and multi-currency capabilities.

  • Automated money movement reduced manual processing overhead for Pleo's operations team.

  • The modular integration architecture enables faster onboarding of future banking partners.

  • Improved observability through Grafana dashboards reduced incident response time.

Business Impact

The new capabilities delivered by Bloomteq directly support Pleo's growth strategy by unlocking new markets through international support, improving customer retention via richer in-app financial management features, and reducing operational costs through automation. The scalable architecture ensures Pleo can continue adding banking partners without significant rework, providing a strong foundation for future product expansion.
