Case Study: Avanza Bank achieves millisecond response and 5X customer growth with GigaSpaces

Avanza Delivers Innovative Banking Services with Millisecond Response Growing Customer Base by 5X

Avanza is a Swedish digital-first savings and investment bank serving 1.7 million customers with stock trading, funds, savings and open-banking services. Rapid commercial growth, a complex estate of 1,600 microservices (running in 6,700 instances/day), 900+ APIs and heavy trading spikes (>280k equity transactions/day) led to latency, database bottlenecks and operational complexity that threatened the customer experience.

Avanza replaced its backend with GigaSpaces’ in-memory platform and built a custom trading stack, enabling 50,000 responses/second (1–2 million calls/second at peak), sub‑0.5s view rendering and 17 TB of in‑memory data. The move delivered millisecond response times, shortened development cycles, reduced infrastructure overhead for 250 developers, and supported rapid, scalable growth (5× customer base) while improving the premium trading experience.
