What Welyft does
Welyft is a Paris-based data marketing agency founded in 2022 by three ex-Uptilab co-founders (Clément Hornec, Léo Denis, Amaury Ortolland) that specializes in Conversion Rate Optimization (CRO), A/B testing, user research, and analytics consulting for B2B clients. The firm operates from a single office at 65 rue Ramey, 75018 Paris, is incorporated as a Société par actions simplifiée (RCS 919 992 917) with €1,500 share capital, and reports no external institutional funding. Welyft sells to enterprise clients across e-commerce, media, lead generation, and SaaS verticals, with named customers including Groupe Etam, Les Mousquetaires (Bricomarché), Salomon, and Sephora.
The agency's service portfolio is organized around four pillars — CRO & Continuous Improvement, Experimentation & Derisking, Data & Analytics, and Upskilling & Training — supported by a proprietary 4-pillar CRO Audit methodology that integrates heuristic analysis, web analytics, behavioral data (heatmaps and session recordings), and Voice of Customer research. Welyft does not sell proprietary software; instead, it implements and certifies on third-party platforms, maintaining Core-tier partnerships with AB Tasty, Kameleoon, Optimizely, Dynamic Yield, Contentsquare, and Hotjar, and Minor-tier partnerships with Algolia, Amplitude, Mixpanel, Piano Analytics, VWO, and others. The firm augments its service offering with free tools (Statistical Confidence Calculator, Chrome A/B Test Detection extension) and has three productized tools in development.
Welyft runs a sales-led B2B go-to-market, acquiring customers through content marketing (blog, Substack 'Wetalk' newsletter), webinars, SEO, LinkedIn, and case-study-driven consultative selling, with quote-based multi-year engagements. Operational scale signals include 60+ customers served, 250 A/B tests launched, and 120 missions completed, delivered by approximately 15-20 consultants and three co-founders.
