Martech startup Fibr AI has raised $5.7 million in a seed funding round led by Accel, with participation from WillowTree Ventures and MVP Ventures. The round also saw backing from several Fortune 100 operators as angel investors.
With this, Fibr AI’s total funding stands at $7.5 million, including a $1.8 million pre-seed round raised in 2024, also led by Accel.
The fresh capital will be used to enhance product capabilities and expand enterprise adoption across global markets.
Founded by Ankur Goyal and Pritam Roy, Fibr AI is building an agentic web experience platform that turns websites into adaptive systems designed to respond to visitor context in real time. The platform focuses on optimising on-site experiences for both human users and AI-driven traffic.
Fibr AI embeds autonomous agents into individual URLs, enabling continuous optimisation and personalisation without relying on traditional A/B testing or manual workflows. The company says this allows websites to adjust experiences dynamically based on audience, channel and intent signals.
The startup claims its enterprise customers have reported reductions in customer acquisition costs and improvements in engagement metrics. Fibr AI currently works with large enterprises across banking, financial services, telecom and healthcare sectors.
