Fibr: The Agentic Web Experience Platform

Fibr transforms your website's URLs into intelligent, adaptive agents. Each page automatically senses visitor intent, makes decisions, and reshapes its experience in real time for whoever arrives. Founded in 2022 and backed by Accel, Fibr combines software infrastructure and AI agents with human-in-the-loop oversight to deliver personalized and dynamic web experiences without requiring engineering changes.

What is Fibr's Agentic Experience Layer?

Fibr provides an agentic experience layer for the modern web that operates on the principle of AI-driven execution with human oversight. The platform's AI agents handle personalization and optimization at scale, while human teams guide the overall strategy, brand alignment, and final decisions. This ensures that every experience is not only personalized but also drives measurable business outcomes and remains fully compliant.

How Does Fibr AI Work?

Fibr is built on three core pillars that work together to turn static websites into adaptive experiences. The platform combines intelligence to understand visitor needs, AI execution to act on those insights, and human governance to ensure control and alignment.

Experience Intelligence: Create Experiences Instantly

Fibr allows teams to create personalized landing pages or transform existing URLs into intelligent, agentic pages powered by AI. This capability enables businesses to deliver relevant experiences from the first visit with no extra work. For example, a financial services page can be adapted to show clear coverage and honest pricing, resulting in a 23% conversion rate lift and an 8/10 visual score from the AI agent.

AI Execution: Always-On Optimization

Fibr’s AI Agents continuously analyze your pages, automatically generate hypotheses for improvement, create new variants, and run AI-led experiments. This "always on" optimization engine constantly learns what works best for different audiences and applies those learnings to improve every subsequent experience without manual intervention.

Assisted Autonomy: AI Execution with Human Oversight

The platform provides a full-stack agentic experience layer where AI agents execute personalization at scale, while human allies guide strategy, brand alignment, and decisions. This model of assisted autonomy ensures every automated experience drives measurable outcomes and adheres to brand standards.

What Impact Has Fibr AI Driven at Scale?

Fibr's platform is designed to deliver measurable results across the entire customer journey. By deploying adaptive experiences, customers have achieved significant performance improvements.

What Can You Personalize with Fibr?

Fibr's AI senses where a visitor's story began and carries it forward, adapting pages on arrival so the experience feels continuous and relevant. The platform enables several types of personalization to improve engagement and conversion.

Ads Personalization

AI-driven pages instantly align with the intent of your ad campaigns, creating seamless experiences that convert visitors with precision. This leads to higher return on ad spend (ROAS), increased lead generation, and better Google Ad quality scores.

LLM-based Personalization

When visitors arrive from an LLM like ChatGPT or Claude, Fibr’s AI interprets their intent and adapts the page content dynamically to match their needs. This results in better page engagement, higher conversion rates from AI-driven traffic, and lower bounce rates.

Journey Personalization

Fibr follows your visitor's journey across your site, adjusting every page they land on to ensure the experience flows seamlessly and intuitively. This helps reduce funnel drop-off rates, improve engagement, and lower customer acquisition costs (CAC).

Audience Personalization

With Fibr, every audience segment sees a tailored experience. The AI adapts your pages based on audience data, making each visitor feel understood and engaged. This improves engagement rates, lead conversion, and time on page.
