Ninetailed is a composable personalization and experimentation solution providing digital teams the freedom to instantly create experiences inside Contentful to personalize, test, analyze, and optimize the customer journey. This allows companies to iterate on and improve their customer experience — ultimately increasing conversion rates and revenue.

With its market-leading APIs and progressive customer profiles that grow with each new data source, Ninetailed makes personalizing, testing, and analyzing digital customer experiences extremely straightforward.

Ninetailed’s 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 Next, React, Node.js, and Gatsby, developers can connect Ninetailed with Contentful in well under an hour!

Ninetailed’s data API connects seamlessly with any data source and analytics solution, building progressive customer profiles that grow with every new piece of data and every new behavioral event — even if the user remains anonymous. Marketing teams can use these profiles to run experiments and A/B tests and 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.

Marketing teams can build, preview, deliver, and experiment with variations directly within Contentful and analyze and understand their personalized experiences and experiments with Ninetailed’s experience analytics solution. Therefore, marketers can focus on what they do best: dreaming up and designing experiences that delight customers to increase their conversions and revenue.
