Case Study: Simply Wall Street achieves faster experiments and team self-sufficiency with Unleash

How Simply Wall Street uses feature flags to deliver sleek 
and accessible analytics

Simply Wall Street, a stock data visualization platform serving over 5 million users in 170 countries with reports on 150,000 stocks across 95 markets, was outgrowing its previous feature-flag solution. They needed better performance and scalability for both backend and frontend scenarios, an intuitive UI that non-engineers could use, and the ability to track and target anonymous users — so they evaluated Unleash and adopted Unleash Enterprise.

Unleash implemented a feature-flagging platform used for experimentation and risk mitigation, enabling multiple teams to work in parallel, evaluate flags with minimal performance impact, and target anonymous cohorts. As a result, Unleash helped Simply Wall Street run more experiments in faster loops, simplify their codebase, increase team self-sufficiency, and get product managers actively involved in rollout strategy.
