Fibr AI, the martech startup pioneering the “Agentic Web,” has raised $5.7 million in a seed funding round led by Accel. The round saw participation from WillowTree Ventures, MVP Ventures, and a group of Fortune 100 operators as angel investors.
This latest infusion brings Fibr AI’s total capital to $7.5 million, following a $1.8 million pre-seed round in 2024, which was also led by Accel. The funding will fuel the startup’s expansion into the U.S. market and accelerate the development of its autonomous website optimization platform.
Moving Beyond the “Static Web”
Founded by serial entrepreneurs Ankur “AJ” Goyal (Stanford GSB, ex-Nestlé) and Pritam Roy (IIT Bombay, ex-CRED), Fibr AI addresses the “personalization gap.” While digital advertising has become hyper-targeted, the destination—the website—often remains a generic, one-size-fits-all landing page.
“Marketing has become intelligent everywhere except the website,” said Ankur Goyal, CEO and Co-Founder of Fibr AI. “We are building a web where every URL operates as a living experience system that understands context and responds in real time—for humans and AI agents alike.”
How it Works: The Agentic Experience Layer
Unlike traditional A/B testing tools that require manual setup and weeks of data collection, Fibr AI embeds autonomous agents into individual URLs. These agents act as a “workforce” for conversion rate optimization (CRO):
-
Real-Time Adaptation: Websites dynamically adjust layout, imagery, and copy based on audience signals, traffic source (Google, Meta, etc.), and user intent.
-
AI-to-AI Interaction: As conversational AI (like ChatGPT or Gemini) begins to research products on behalf of users, Fibr AI ensures websites are “agent-readable,” providing specific data to these automated systems.
-
Autonomous Experimentation: The platform runs thousands of parallel micro-experiments, continuously self-optimizing without human intervention.
Rapid Enterprise Adoption
Fibr AI is already being utilized by large, regulated enterprises in banking, telecom, and healthcare. Early rollouts have delivered a 20%+ conversion uplift and up to 50% lower customer acquisition costs (CAC).
Prayank Swaroop, Partner at Accel, noted: “CMS platforms are effective at publishing content, but not at understanding context. The website can’t just be a destination—it has to respond immediately and intelligently. Fibr brings AI agents directly into the experience layer to make true one-to-one experiences possible at scale.”
