UX KEY

What UX KEY does

UX-KEY SAS is a French UX design agency and software publisher headquartered in Metz, France, founded in 2019 by three engineers — Loïc CUERONI (President, École Centrale Paris), Michel KUEHN (Technical Director, Telecom Nancy), and Pierre-Louis JAEGER (Scientific Director, École Centrale Lyon). The company develops a proprietary AI-powered diagnostic platform that collects anonymized user behavior data (mouse positions, movement velocity, clicks) via a lightweight RGPD-compliant script and reconstructs navigation journeys to surface friction points in SaaS applications, web applications, and digital interfaces. The AI engine is complemented by a 3-step audit methodology combining behavioral data collection, page-level ergonomics/accessibility/UX-writing analysis, and compliance verification against UX/UI standards. UX-KEY also holds a filed patent (FR3110269) and conducts monthly collaborations with leading French computer science laboratories including Centrale Supélec Metz and LCOMS at the Université de Lorraine. The company conducts over 1,200 UX studies per year and lists more than 120 partner references. Data is hosted on European Scaleway infrastructure under full GDPR compliance with a dedicated RGPD referent.

UX-KEY generates revenue through two streams: (1) professional services including ergonomic audits, UX research, prototyping and mockup design using Figma, and RGAA digital accessibility compliance — typically billed on a project or retainer basis — and (2) a SaaS analytics component derived from the proprietary diagnostic tool, which produces recurring revenue through ongoing monthly data collection and reporting. Distribution is sales-led and quote-based, with no public pricing tiers; prospects engage via a website contact form or Google Calendar appointment booking. The primary customer segments are B2B SaaS software publishers (with stated use cases covering churn reduction, conversion uplift, and developer-time savings), web application developers, and public institutions/collectivités requiring RGAA compliance. Named clients include Chronocaisse, DIMM.UP, Job Explorer, and Superactifs, with broader references spanning BtoB, BtoC, services, industry, legaltech, communication, HR, telecoms, and silver economy.

The company operates in 4 countries — France (HQ), Luxembourg, Germany (UX-KEY GmbH, Frankfurt), and Canada (EX-CLÉ subsidiary, Sherbrooke, Quebec) — and reported €4.5M in revenue with 25 employees as of February 2025. According to the company's own history page, revenue tripled each year through 2023. UX-KEY is privately held with no parent company and no subsequent venture funding beyond the 2019 Initiative Metz / Bpifrance grants; founder ownership and control remain intact.

Direct peers

• Hotjar: Self-serve SaaS product for heatmaps, session recordings, and user feedback targeting product and UX teams. Direct competitor to UX-KEY's behavioral analytics software layer, with broader SMB reach but no bundled consulting service or EU-only data residency.
• FullStory: Digital experience analytics platform with session replay, heatmaps, and AI-powered insights for product and UX teams. Comparable product offering to UX-KEY's AI behavioral diagnostics, aimed at digital product optimization.
• Smartlook: Product analytics tool with session recording, heatmaps, and event-based analytics for websites and mobile apps. Comparable in offering AI-augmented UX analytics aimed at product teams, with similar mid-market positioning.
• Crazy Egg: Heatmap, scrollmap, and user-session analytics platform targeting SaaS and e-commerce sites. Comparable as an entry-level UX analytics tool; UX-KEY differentiates via AI depth, expert consulting, and European data residency.
• Contentsquare: French-founded digital experience analytics platform offering behavioral analytics, session replay, and UX insights for enterprise websites and apps. Closest direct peer: same geography (France), same target customer (enterprise/SaaS product teams), overlapping AI-driven behavioral analytics capability.

Broad incumbents

• Frog (Capgemini Engineering): Global design and innovation consultancy offering UX strategy, research, and product design services. Comparable to UX-KEY's consulting arm (ergonomic audits, prototyping) but at enterprise scale with broader geographic reach.
• UserTesting (now UserZoom): Enterprise-scale human insight platform for usability testing, surveys, and video-based user research. Broader incumbent offering UX research services that overlap with UX-KEY's ergonomic audit and UX research deliverables at enterprise scale.
• Amplitude: Enterprise product analytics platform for digital products, with behavioral cohorts and AI-driven insights. Overlaps with UX-KEY's behavioral analytics and friction-point identification, though broader in scope and not UX-specialized.

Emerging players

• Maze: Continuous user research platform for prototype testing, surveys, and usability studies. Adjacent competitor addressing the UX research portion of UX-KEY's service offering, with stronger self-serve SaaS positioning.
• LogRocket: Frontend monitoring and session replay tool with product analytics overlays for engineering and product teams. Comparable AI-augmented behavioral analytics offering, though more developer-centric than UX-KEY's UX designer-centric approach.
