AB TastyWHO WE ARE
Ready to shape the future of digital optimization as part of Wingify, the company bringing VWO and AB Tasty together?
Wingify brings VWO and AB Tasty together as one company, and one platform, built to make every digital experience relevant in the moment it happens. Following the merger of the two pioneers earlier this year, we unify experimentation, personalization, customer insights, commerce optimization, feature management, and customer engagement on a shared data foundation, with AI built into the core rather than bolted on top, powered by Wingz, our embedded AI engine. We call this Agentic Experience Optimization.
Wingify brings together more than $105 million in revenue, 4,000 customers, and 700 employees across 11 offices worldwide, two teams that have each spent over 15 years in digital experience optimization. We serve brands including L'Oréal, LVMH, Decathlon, Puma, Forbes, Motorola, AXA, and De Beers, and we are building the future of digital optimization, powered by AI, experimentation, personalization, and data.
Our mission is simple: help brands grow by creating meaningful user experiences that drive business performance.
Joining us means stepping into a dynamic, international environment where innovation, ownership, and impact are not buzzwords—but daily realities.
Our culture is driven by strong values:
We bring client satisfaction
