The Any-Stack
Alternative to Ninetailed
Ninetailed lives inside Contentful’s headless stack. Personyze is built for Growth Teams. Get the same full personalization power—Recommendations, Testing, and CDP—on any site, no headless re-platform required.
No Headless Re-Platform Required
Ninetailed (now Contentful Personalization) is a modern personalization layer, but it lives inside Contentful’s composable stack—so unless you’ve already gone headless, it is out of reach. It’s API-first and developer-led, and getting value means adopting Contentful’s enterprise CMS (often €40k–€100k+/yr) and building the front end around it.
Personyze democratizes this power. We believe you shouldn't need a Fortune 500 budget to deliver a personalized experience. Our platform offers the same unified "Growth Stack"—combining A/B testing, AI Recommendations, and a CDP—into one agile, transparently priced solution.
