What Global Web Index does
GWI (legally Trendstream Limited in the UK, GlobalWebIndex Inc in the US, both wholly owned by GlobalWebIndex Holdings Limited) is a London-headquartered SaaS and data company that sells syndicated consumer-insight subscriptions to brands, agencies, media organizations, and sports, gaming, and finance teams. The company operates a global online survey panel covering 52 markets representing roughly 2.8 billion people, conducting over 2 million interviews per year and aggregating 35 billion data points refreshed quarterly across four data waves, with 15+ years of trended history.
The core product is the GWI Platform, an on-demand consumer-insights workspace offering interest, attitude, and buying-habit exploration across 50+ markets. Adjacent offerings include Respondent Level Data (RLD) for individual-level analytics, Audience Activation, Fusions (data-partnership combinations), Brand Tracking, Segmentation, Audience Profiling, Ad Effectiveness, Concept Testing, Analyst Hours, Synthetic Audiences, Retail Media Data, and GWIQ (a cookie-based advertising-effectiveness service). GWI sells API access on a subscription basis and embeds insights directly into client systems, dashboards, and AI tools. In 2025 the company launched Agent Spark, a conversational AI-powered insights analyst that queries the 35-billion-point survey corpus to deliver analyst-quality answers in natural language without using web-scraped prompts.
GWI monetizes primarily through multi-year enterprise subscriptions to the Platform and APIs (continuous access during the subscription term), professional services for custom research, integrations revenue, and data-monetization streams from pseudonymized RLD and custom activations — supplying pseudonymized respondent-level data to major advertising holding companies including Publicis (Epsilon), WPP, IPG, Omnicom, and Accenture, as well as to the global professional services firm Accenture. Go-to-market combines enterprise field sales with 30-minute tailored demos, inside sales, an API-first distribution model, and a product-led-growth self-serve surface for smaller teams, supported by a GWI Partner Program for resellers. Customers include agencies (Passion Digital), social platforms (Nextdoor), and sports organizations (One Championship), with additional insights referenced by Threads and Bluesky. The company employs 501–1,000 people globally across London, New York, Athens, Prague, and Singapore.
