Fibr AI Secures $5.7M Seed Funding to Expand AI-Powered Website Personalization Platform

Fibr AI, an emerging martech startup focused on autonomous website optimization, has raised $5.7 million in seed funding led by existing investor Accel. The capital injection, equivalent to approximately INR 52 crore, will fuel the company's expansion efforts as it scales its agentic AI-powered platform designed to transform how enterprises approach conversion rate optimization (CRO) and user experience personalization.

Founded in 2023 by Ankur "AJ" Goyal and Pritam Roy, Fibr AI addresses a critical inefficiency in digital marketing: while companies invest millions optimizing advertisements, emails, and campaign targeting, their actual websites often remain static and generic. This disconnect results in broken user journeys and wasted marketing spend when visitors land on pages that fail to match the intent signaled by their arrival source.

The platform operates as an intelligent layer on top of existing websites, using AI agents to detect how visitors arrivewhether from paid ads, search results, recommendations, or AI systems like ChatGPT and Claudeand automatically adjusts page content in real time. This includes headlines, imagery, layouts, and user flows, all without requiring code modifications or large teams of optimization specialists.

Fibr's technology relies on three primary AI agents working in concert: a personalization agent that tailors content to specific user segments, an experimentation agent that generates and tests variations autonomously, and a performance agent that monitors results and optimizes continuously. This autonomous approach replaces traditional CRO methods, which are typically slow, expensive, and heavily dependent on human teams conducting manual A/B tests.

The platform integrates seamlessly with existing martech infrastructure, connecting to popular tools including Adobe Target, Optimizely, Google Analytics 4, HubSpot, and major advertising platforms like Google, Meta, and LinkedIn. This integration capability enables marketers to automate their entire CRO workflow without disrupting existing systems or requiring extensive technical overhauls.

Fibr AI has already attracted notable enterprise customers, including India's largest insurance provider and a $3 billion broadband company. Early adopters have reported approximately 10% improvements in conversion rates and lead quality, alongside gains in overall productivity and efficiency. The company currently serves 12 enterprise customers and aims to expand to 50 by year-end.

The startup's early success in regulated industries such as banking and healthcare is particularly significant. These sectors typically operate with standardized, rarely-updated website infrastructure and face strict compliance requirements. Fibr's built-in governance, security features, and privacy controls address these concerns, allowing enterprises to move quickly while maintaining regulatory compliance.

Beyond its core CRO platform, Fibr offers complementary products designed to enhance marketing efficiency. Pilot enables marketers to create personalized landing pages for campaigns across ads, emails, and SMS channels. Blocks allows teams to adapt and repurpose existing content across different formatsconverting a high-performing Facebook ad into a blog post or Google search ad, for example.

The company has also developed specialized capabilities for AI-driven traffic. Fibr automatically detects visitors arriving from large language models and serves customized experiences tailored to their research stage and intent. This feature recognizes that LLM-referred users have often already researched product categories and benefit from technical documentation, feature comparisons, and direct paths to trials rather than traditional marketing messaging.

Fibr enters a market long dominated by established players like Adobe and Optimizely, which typically require significant agency support and engineering resources. By automating the experience layer and minimizing manual intervention, Fibr positions itself as a more accessible alternative for enterprises seeking to future-proof their digital experiences as AI-driven traffic continues to grow.

The $5.7 million seed round will support expansion of Fibr's sales and customer-facing teams in the United States while continuing technical development in India. As the company scales, it aims to demonstrate that websites can evolve from static assets into intelligent, self-optimizing systems that adapt in real time to every visitor's unique context and intent.
