In just three years, Yassir scaled from 50 engineers to 400, serving 8 million customers across 45 cities. This rapid growth came with a price: tangled team structures, misaligned priorities, and mounting delivery bottlenecks. In this case study we show how Team Topologies helped turn chaos into clarity and faster flow.

This case highlights how applying Team Topologies principles can evolve an organization into a high-performing, empowered ecosystem capable of delivering value faster, with greater sustainability and team well-being. REA Group’s Financial Services division undertook a major transformation to address slow delivery, high cognitive load, and inefficiencies caused by large, monolithic teams. By adopting Team Topologies, the organization restructured into small, autonomous, stream-aligned teams and introduced a strong focus on flow efficiency, intentional ways of working, and cognitive load management.
