About the Ninetailed Personalization and Experimentation app

Ninetailed is a composable personalization and experimentation solution which provides digital teams the radical freedom to instantly create experiences to personalize, test, and optimize the customer journey. This allows companies to iterate on and improve their customer experience without ever leaving the Contentful interface. With its market-leading APIs and customer profiles that grow with each new data source, Ninetailed makes personalizing, testing, and unifying customer experiences extremely straightforward.

Integration with a composable stack is painless, freeing up developers to quickly move on to bigger and better tasks. With SDKs and plugins for modern frontend frameworks like Gatsby, Next, React, and NodeJS, developers can connect Ninetailed with Contentful in well under an hour! (Can you beat the current record of 26 minutes?)

Ninetailed’s data API connects seamlessly with any data source and analytics solution, building unified customer profiles that grow with every new piece of data and every new behavioral event — even if the user remains anonymous. Digital teams can use these profiles to create anything from 1 to 1 personalized experiences to full multi-channel customer journeys. Ninetailed’s everything-on-the-edge approach to both data and delivery means experience variations cause zero loading lag and zero interruptions for the customer.

Creative teams can build, preview, deliver, and experiment with variations directly within Contentful, focusing on what they do best: dreaming up and designing experiences that delight customers.
