VWO is a conversion rate optimization (CRO) and experimentation platform from Wingify that enables companies to continuously improve digital experiences across websites, mobile apps, and backend services. Originally launched as Visual Website Optimizer, the product pioneered an intuitive visual editor for A/B testing so marketers could launch experiments without relying heavily on developers. Today, VWO has evolved into a connected, AI-driven platform that brings together behavior analytics, experimentation, personalization, feature flagging, and data management in one unified environment.
Founded in 2009 in New Delhi, India, VWO grew as one of the early bootstrapped SaaS success stories from India, serving thousands of customers globally without raising venture capital. In early 2025, private equity firm Everstone Capital acquired a majority stake in Wingify, providing significant growth capital while VWO remained a standalone SaaS platform focused on experimentation and experience optimization. The company reports more than 50 million dollars in annual recurring revenue and serves over 3,000 brands worldwide, including enterprises such as Amazon, Domino’s, Disney, eBay, Lego, and the World Economic Forum.
VWO’s platform is structured into modular products: VWO Testing for web experimentation, VWO Insights for behavior analytics (heatmaps, session recordings, forms and funnels, surveys), VWO Personalize for real-time targeting and personalization, VWO Feature Experimentation and VWO Mobile Insights for server-side and mobile app testing, and VWO Rollouts and Data360 for controlled feature rollouts and centralized event data. These modules sit on top of a shared data layer and are enhanced by VWO Copilot, an AI assistant that surfaces insights, generates test ideas, creates copy variations, and helps define audiences and metrics.
Positioned as a mid-market and enterprise-grade alternative to tools like Optimizely and AB Tasty, VWO emphasizes ease of use, strong customer support, and enterprise security. It offers ISO 27001 and ISO 27701 certifications, SOC 2 Type II attestation, and GDPR, HIPAA, PCI DSS and CCPA readiness, backed by Google Cloud Platform data centers in multiple regions. With 450+ employees and offices in India, Europe, and the US, VWO continues to expand globally, investing in AI-first experimentation workflows and deeper integrations with analytics, CDPs, eCommerce platforms, and marketing stacks.
