Boost

Boost puts AI at the heart of its work as an agency focused on Conversion Rate Optimization (CRO) and digital analytics. Headquartered in Barcelona, with teams in Miami, Panama City and Tallinn, we help ecommerce, SaaS and hospitality brands earn more from the visitors they already attract—without raising their advertising budgets. Our approach is grounded entirely in data. By bringing together GA4 insights, heatmaps, session replays and A/B experiments, we uncover ways to improve conversion and test each proposed change before it goes live. That means no hunches or personal opinions—just evidence-led decisions with results measured in euros. A few outcomes achieved with our clients: - Catalonia Hotels: €708,815 in extra monthly revenue through booking engine improvements - The Excellence Collection: $1M in added revenue from nine experimentation initiatives - DogfyDiet: Average conversion rate up 47.8% across its subscription journey - Mim Habits: Conversion growth of 136% from 23 initiatives over 10 months We also created Scan&Boost, an AI-based CRO auditing platform that reviews any website in minutes and provides practical recommendations for improvement. After delivering more than 1,000 experimentation initiatives and generating an additional €7.8M for clients, Boost helps ambitious companies scale more intelligently—not simply get bigger.
