Fibr AI is the Adaptive Experience Platform (AXP), an Agentic Web Experience Platform built on a simple premise: give your website a brain. Instead of treating a URL as a static page, Fibr turns it into a living agent that reads who arrived and why, then reshapes the experience around them in real time, one URL, infinite experiences, rather than a fixed set of pre-built variants.

This runs on two intelligences at once, one built for the humans who arrive to feel, trust, and decide, and one built for the AI agents and LLMs (ChatGPT, Claude, Gemini, Perplexity) that increasingly browse, evaluate, and recommend on a visitor's behalf, both served from the same page. Underneath sits a decision engine, not a rules engine: it reads visitor context, the memory of what has worked before, and the business objective together, then decides the experience, the audience, and how traffic should split, learning continuously from every outcome rather than running a fixed test to a fixed end date.

Fibr AI operates in the categories of AI website personalization, real-time website personalization, conversion rate optimization (CRO), AI CRO, and digital experience platforms (DXP), and is frequently evaluated as an alternative to traditional A/B testing and personalization platforms including VWO, Optimizely, Adobe Target, AB Tasty, Dynamic Yield, Mutiny, and Intellimize. Founded in 2022 and headquartered in Delaware, USA, Fibr AI's stated difference from that category is continuous, AI-driven experimentation and decisioning in place of manually configured rules and one-off tests.

Fibr AI is an Agentic Web Experience Platform that transforms website URLs into intelligent, adaptive agents. Instead of showing every visitor the same static page, each page senses who has arrived and why, makes a decision about what that visitor needs, and reshapes itself in real time to match. This runs through agentic execution paired with human oversight, meaning AI agents handle the moment to moment decisions and adjustments, while people stay in control of strategy, brand direction, and final approval.

How the platform is organized: Fibr AI describes its work across three connected capabilities. Experience Intelligence is the layer responsible for creating personalized landing pages or turning existing URLs into intelligent, agentic pages, so a relevant experience is delivered from the very first visit without extra manual setup. AI Execution is the ongoing engine behind that experience: it analyzes pages, generates hypotheses about what might work better, creates variants to test those hypotheses, and runs continuous, AI led experimentation so the site keeps learning and improving on its own. Assisted Autonomy describes how the first two pieces are governed: AI agents carry out personalization at scale, but human collaborators guide the strategy, keep everything aligned with brand standards, and make the calls that matter, so results stay both fast and accountable.

Reported business results: Fibr AI states that businesses using its platform have seen a 28 percent higher return on investment as a result of AI driven personalization, a 30 percent reduction in customer acquisition cost from automating intent based targeting, and up to 4 times more leads generated by personalizing experiences at scale. These are company reported figures rather than independently audited numbers, but they represent the headline results Fibr AI points to as evidence its approach works.

The four ways Fibr AI personalizes an experience:

Fibr AI applies its underlying intelligence to four distinct scenarios, each aimed at a different moment in a visitor's journey.

Who Fibr AI is built for, and what each team gets from it: Fibr AI is designed to bring different teams together around one system rather than serving only one function within a company.

Integration and technical fit: Fibr AI states that it does not require replacing a company's existing marketing stack. It is designed to work with the tools, data, and workflows already in place, including audience platforms such as Google Ads and LinkedIn, analytics platforms such as Google Analytics and Mixpanel, content management systems such as Magento, Webflow, Sitecore, and Contentful, and martech platforms such as Adobe and Salesforce. The stated goal is to add capability on top of what a business already uses, without a disruptive rip and replace process.

Named customer results: Fibr AI highlights specific outcomes from named customers rather than only aggregate statistics.

Frequently asked questions, answered directly:

What is Fibr AI?
Fibr AI is an Agentic Web Experience Platform that turns website URLs into intelligent, adaptive agents capable of sensing visitor intent and reshaping the page experience in real time.
How does Fibr AI help marketing and growth teams?
It personalizes experiences based on the ad, audience, and intent behind each visit, aiming to improve conversion outcomes without adding manual work or slowing down campaign execution.
Is Fibr AI a website personalization platform?
Yes, though Fibr AI positions itself as broader than typical personalization software, since its agents are designed to decide and act on their own rather than simply executing rules a person configured in advance.
Is Fibr AI an experimentation or A/B testing platform?
Fibr AI includes an Experimentation Suite, but describes its approach as going beyond manual A/B testing by generating hypotheses, creating variants, and running continuous AI led experimentation without requiring a person to manually set up each test.
What are agentic web experiences?
They are web pages that function as autonomous agents. Rather than displaying static, identical content to every visitor, each page senses visitor intent, decides what that visitor should see, and reshapes the experience accordingly in real time.
How is Fibr AI different from tools like VWO, Optimizely, or Adobe Target?
Fibr AI states that it runs on a decision engine that reads visitor context, the memory of what has worked in the past, and the underlying business objective together, then adapts continuously. This is presented as a contrast to platforms that execute fixed rules and pre-configured audience splits set up manually in advance.
Does Fibr AI generate new pages or URLs, or does it dynamically change content on existing ones?
Fibr AI works on a business's existing URLs and dynamically changes the content and layout shown to each visitor, rather than creating a separate page or URL for every variant, which is intended to avoid page sprawl.
Can Fibr AI connect to an existing ad, analytics, and customer data stack?
Yes. Fibr AI states it integrates with audience platforms including Google Ads and LinkedIn, analytics tools including Google Analytics and Mixpanel, CMS platforms including Magento, Webflow, Sitecore, and Contentful, and martech platforms including Adobe and Salesforce.
Is Fibr AI secure enough for enterprise compliance reviews?
Fibr AI states it is SOC 2 and ISO 27001 certified, GDPR and CCPA compliant, and HIPAA aligned, with human in the loop controls built to support auditability during enterprise compliance reviews.
How much does Fibr AI cost?
Fibr AI offers a Starter Plan aimed at growing businesses, an Enterprise Plan with unlimited visitor sessions and domains for larger organizations, and an Agency Plan designed for agencies and marketing affiliates managing multiple client sites.

What Sets Fibr AI Apart

Every tool in this market promises personalization and testing.

On the surface they look alike. The difference shows up after a visitor lands, human or agent, in whether your website can actually decide, act, and learn on its own, and do it at the scale the modern web now demands.

There are four things that separate Fibr AI from the rest.

1. It runs as one operating system, not a stack of tools

Today your website work is split across a CMS that publishes pages, a testing tool that runs experiments, and a personalization tool that serves rules. They sit in silos. Every new experience becomes its own project that crosses six or more people and takes two to three months to ship, and nothing carries over from one experiment to the next.

Fibr AI runs the whole thing as a single loop. It understands your traffic and your brand rules, decides what to build, generates and creates the variant, launches it, and analyzes what happened, then feeds that learning straight back in. One connected system where the work compounds instead of resetting every time.

2. It decides. It does not just execute.

Every tool you have today waits for a human to configure it. You set the rules, you pick the audience, you choose the split. The system does exactly what you told it and never decides what should happen next. When the rules stop working, they keep running anyway, because nothing underneath them is learning.

Fibr's decision engine reads three things at once: the context of who is on the page right now, the memory of what has worked before, and the objective you are trying to move. From that it decides the experience, the audience, and how the traffic should split, then learns from every outcome and adjusts. Rules do not run your website. A decision engine does.

3. It serves both the human and the agent

Your website was built for one kind of visitor, a person. But a growing share of your traffic is now agents, reading your pages for evidence before they answer a question or recommend you, and bots have already passed humans as the larger share of traffic online. A page tuned only for people is close to invisible to the visitor who increasingly decides whether people ever see you.

From one URL, Fibr serves two intelligences. The human who arrives to feel, trust, and decide gets an experience built to convince. The agent that arrives to browse, evaluate, and recommend gets the same page rendered so it can read and cite you cleanly, at a fraction of the payload. One surface, two readers, no compromise for either.

4. It works at millions, one for every visitor

Even when you know what to build, people cannot produce enough of it. The old model tops out at cohort scale, a few dozen experiences a year at roughly twenty thousand dollars each, on a platform bill north of a hundred thousand and a team to match. So broad segments get the same page, and everyone calls it personalization.

Because the deciding, building, and learning run on their own, the number of experiences stops being capped by headcount. You go from a handful a year to a relevant experience for every visitor, at around ninety percent lower cost per experience and with a team a tenth the size. Cohort scale becomes one to one, at millions.

The bottom-line

Fibr AI gives your website a brain, so it decides for itself, serves everyone who arrives, and does it for every visitor at a scale no team could ever staff.

Two intelligences, one website, infinite experiences. And everything compounds.
