Our Story

Personalization Was Slow, Breaking the Website Workflows, and Unable to Scale. We Built Ninetailed to Change This

Nowadays, we have more data than ever, sitting in different systems and platforms. Producing content is easy and affordable, but showing the right content to the right person is still a big question.

To tailor every experience, we need to solve the biggest unsolved challenge around personalization: How to Deliver Personalized Experiences at Scale?

Ninetailed was started by Andy and Alex to solve their own problem, creating landing pages at scale that are personalized for paid traffic and location.

Traditional solutions were not built for the modern web, slowing down websites, breaking the website flow, and unable to scale.

To change this, Alex and Andy started building Ninetailed on composable MarTech principles by closely working with the early users of the product.

Continuous Optimization of Tailored Experiences Is the Future

Personalization has emerged as the holy grail for marketers in the digital age, yet achieving this at scale with legacy tools has been like finding a needle in a haystack. Traditional marketing technologies often fall short, unable to bridge the gap between vast amounts of customer data and the actionable insights needed to deliver personalized experiences.

Ninetaied is a composable personalization solution built with composability and MACH principles at its core, giving businesses the tools for tailored experiences, scalability, and continuous optimization.

By bridging the gap between datacustomer, content, and experience, composability, and AI, Ninetailed empowers businesses to turn infinite content and customer data into the best possible personalized experiences delivered at the right time, in the right format, and via the right channel.

Visionary Technology

Personalization at Scale Is a Loop That Constantly Optimizes the Experiences

Personalization at scale requires data, content, streamlined workflow, and continuous optimization. Personalization at scale is not climbing up a pyramid but rather a loop that needs to optimize itself from every interaction:

  • Analyze

    Identify segments and individual audience characteristics by leveraging past experiments, behavior, and conversion data.

  • Create

    Produce the content variants for personalized experiences.

  • Experiment

    Discover, based on data, what resonates best with the audiences.

  • Personalize

    Deliver the most effective content variant to a given audience.
