Case study
Challenge
A multinational fast-food brand serving 69M+ customers daily across 100+ countries needed mobile performance validation under 6M active users and 2M+ offer subscriptions per hour — with little prior mobile NFT and a complex five-tier stack.
Approach
VST stood up CoE deliverable templates, validated mobile portfolios in four countries, and ran endurance (72-hour) and failover tests while analysing AWS capacity and competitor feature gaps.
