Kameleoon

Kameleoon is a Paris-headquartered experimentation and personalization platform with offices in the US, Canada, UK, Germany and Switzerland. It combines web and feature experimentation with AI-driven personalization in a single platform, supporting client- and server-side A/B and multivariate tests with linear or multi-armed bandit traffic allocation, and personalization based on price sensitivity, channel, behaviour, persona, 45+ built-in criteria or any data-layer segment. PBX (Prompt-Based Experimentation) lets teams launch tests by chatting with AI. Pricing is custom; the A/B testing offer reportedly starts around $35,000 per year and scales with traffic.
