Case Study: Retisio achieves reliable, scalable event-sourced trading with Akka Platform

RETISIO and AIEnterprise help a major retailer accelerate page-loading, boost conversion, and cut costs

StashAway is a Singapore-founded digital wealth manager that uses its ERAA (Economic Regime–based Asset Allocation) robo‑advisory framework to deliver transparent, low‑cost investment services. The company needed a way to aggregate thousands of individual client trades into omnibus accounts and guarantee timely, auditable settlement under strict regulatory rules—so transactional correctness, reliable message delivery and a full audit trail were critical.

To meet that need StashAway deployed Lightbend’s Akka Platform for native event sourcing across its microservices-based trading stack, ensuring guaranteed message delivery, accurate ledgers and scalable processing. The result: rapid growth and strong reliability—daily trades scaled from ~100k ($4M) to ~200k ($15M) in a year, quarterly volumes now include millions of orders and transactions, assets under management topped $1B, and the platform has delivered high availability with minimal operational overhead.
