Neo Bank Asia case study

VC-backed neobank scaling across Eastern Europe with digital services for people and businesses

Challenge

Neo Bank Asia aimed to enter the market with a digital lending experience that could compete on both speed and scale. They identified car loans for new-to-bank customers as an ideal entry point, but existing systems lacked the speed, automation, and flexibility required to support rapid lending at scale.

The bank needed a modular lending engine capable of processing loan applications in minutes, integrating with national data sources, and adapting to new credit products without rebuilding the core. Compliance, scalability, and fast time-to-market were non-negotiable.

Solution

We designed and implemented a modular lending platform with high-speed decisioning and flexible orchestration.

• Built a cloud-native credit engine with event-driven architecture and granular APIs

• Integrated with national ID, police, and pension databases, as well as public and private credit bureaus

• Used ML models to extract and validate vehicle data via VIN and photo recognition

• Enabled visual process orchestration with Elsa Workflows — allowing analysts to manage flows without dev involvement

• Delivered frontend onboarding via micro-frontend apps enabling fast iteration

• Adopted ISO 20022 formats and containerized infrastructure for future interoperability

• Deployed with real-time data sync, failover, and multi-environment support — all open source, no licensing overheads

• Designed for reuse across SME and unsecured lending products, with SME lending next in line

Impact

• 85% of car loan applications processed end-to-end without manual intervention

• Decision time reduced from ~2 days to under 10 minutes

• Custom engine delivered in 12-month timeframe (Apr 2024 – Apr 2025)

• First market rollout completed in Eastern Europe

• Lending infrastructure now serves as backbone for future products and regions
