Fibr AI — Building the Agentic Web Experience Layer for Modern Marketing

Introduction — Why Fibr AI Matters Now

In the age of AI, most marketing stacks have become automated and data-driven — except one critical component: the website. Despite smarter ads, advanced analytics and personalized email campaigns, the average website remains static, delivering the same experience to every visitor regardless of intent, source or behavior.

Fibr AI is challenging this limitation by turning websites into intelligent, adaptive agents that sense user intent and dynamically reshape digital experiences in real time. Founded in 2023 by serial entrepreneurs Ankur “AJ” Goyal and Pritam Roy, the startup is building what it calls an agentic web experience layer for enterprises and growth teams.

The company’s mission is simple but ambitious:
make websites behave like intelligent sales and marketing teams.

The Problem — Static Websites in a Dynamic World

Modern marketing has become hyper-personalized across channels, but once a user lands on a website, personalization often stops. Most websites:

• Deliver identical pages to all visitors
• Require manual A/B testing
• Depend on slow experimentation cycles
• Fail to connect campaign data to real-time user behavior

This creates friction between marketing spend and conversion outcomes. Fibr AI argues that websites should not be static destinations — they should be adaptive, learning systems that continuously optimize themselves.

The Product — An AI-Driven CRO Agent Workforce

1. Adaptive Web Experience Agents

Fibr AI turns each webpage into an intelligent agent capable of:

• Understanding visitor intent
• Adjusting content dynamically
• Personalizing landing pages
• Running experiments autonomously
• Optimizing for conversions in real time

Instead of marketers manually testing headlines or layouts, the AI continuously learns and adapts experiences for each visitor.

2. Autonomous CRO (Conversion Rate Optimization)

Fibr’s platform functions as a full-stack AI CRO engine that can run multiple experiments simultaneously, dramatically increasing testing velocity. It enables companies to run far more experiments at faster speeds and lower cost than traditional CRO workflows.

Key features include:

• Real-time personalization
• AI-generated landing pages
• Behavior-based content changes
• Automated A/B testing
• Conversion analytics

The platform’s AI agents (such as personalization and experimentation agents) allow marketing teams to focus on strategy while automation handles optimization.

Technology — The Agentic Web Layer

Fibr AI positions itself as an agentic AI platform, where digital interfaces act autonomously to improve outcomes.

Its core philosophy:

Digital experiences should become self-optimizing systems that learn and evolve continuously.

This model reflects a broader shift toward agentic AI — systems that perceive context, make decisions and take actions autonomously to achieve goals.

Instead of relying solely on human marketers, Fibr deploys AI agents that can:

• Interpret visitor behavior
• Generate personalized content
• Optimize layouts
• Reduce customer acquisition costs
• Increase ROI

Founders & Leadership

Fibr AI was founded by:

• Ankur (AJ) Goyal — CEO
  A serial entrepreneur and Stanford MBA, previously building data and growth platforms.
• Pritam Roy — Co-Founder & CPO
  Former operator at companies like CRED and Rippling, with deep experience in growth and product scaling.

Together, the founders bring more than two decades of experience across consumer tech, marketing, and SaaS. Their backgrounds in building and scaling companies shaped Fibr’s focus on real-world growth outcomes rather than theoretical AI tools.

Funding & Growth

Fibr AI has gained strong investor backing early in its journey:

• Pre-seed funding: about $1.8 million to build its AI personalization platform.
• Seed funding: about $5.7 million led by Accel, with additional investors including WillowTree Ventures and others.

This funding signals growing investor confidence in AI-driven marketing infrastructure and the shift toward agentic web experiences.

Market Opportunity

The global martech and CRO market is evolving rapidly as:

• Privacy changes reduce third-party tracking
• Customer acquisition costs rise
• Personalization expectations increase
• AI adoption accelerates

Fibr AI addresses these shifts by helping companies rely more on first-party data and adaptive experiences, making it highly relevant in a privacy-first digital landscape.

Its platform is already being used across sectors including SaaS, fintech, insurance and e-commerce to improve engagement and conversion rates.

Multi-Role Perspectives

Journalist Lens

Fibr AI represents a broader transformation in marketing — moving from static interfaces to intelligent, adaptive digital systems that behave like autonomous growth teams.

Product Lens

The company’s biggest strength lies in its integration layer. Instead of replacing marketing tools, Fibr sits on top of existing stacks, enabling personalization without rebuilding infrastructure.

Investor Lens

AI-driven CRO is becoming a foundational layer of the digital economy. With strong early funding and a clear enterprise use case, Fibr AI sits at the intersection of AI infrastructure and revenue optimization.

Operator Lens

For growth teams, Fibr reduces manual experimentation and enables faster iteration cycles — turning optimization into a continuous process rather than periodic testing.

Why Fibr AI Is a Disruptor

Fibr AI is disruptive because it redefines what a website is.

Instead of a static digital brochure, the website becomes:

• An AI agent
• A conversion engine
• A real-time personalization system
• A revenue optimization layer

This shift could fundamentally reshape how companies think about customer journeys and digital growth.

The Bottom Line

Fibr AI is building the intelligent web layer for the next generation of digital experiences. By transforming websites into adaptive AI agents, the startup is positioning itself at the center of marketing, growth and customer experience infrastructure.

If the future of software is agentic, then the future of websites will likely look a lot like what Fibr AI is building today.
