Mambai, Feb 05 : Martech startup Fibr AI has secured $5.7 million in a seed funding round led by Accel, with additional participation from WillowTree Ventures, MVP Ventures, and several angel investors. The latest raise follows a $1.8 million pre-seed round completed in 2024, also backed by Accel, signalling continued investor confidence in the company’s vision.
Established in 2023 by Ankur Goyal, an alumnus of Stanford Graduate School of Business and IIT Delhi, along with IIT Bombay graduate Pritam Roy, the company is developing what it describes as an “agentic web experience layer.” The technology aims to convert traditional websites into intelligent platforms capable of adapting content dynamically based on visitor behaviour and context.
The platform enables enterprises to deliver personalised interactions not only to human users but also to AI-powered systems such as language models, automated agents, and web crawlers. By embedding autonomous agents into individual URLs, each webpage can interpret user intent, analyse engagement patterns, and modify elements instantly to improve outcomes.
Drawing from his earlier experience working on consumer brands like Maggi and Paperboat, Goyal said the objective is to eliminate the disconnect between marketing campaigns and on-site messaging. The system replaces manual personalisation and conventional A/B testing with continuous optimisation, linking operational costs directly to measurable metrics such as engagement and conversion rates.
Explaining the approach, Goyal noted that targeted advertisements often lead users to generic landing pages despite being tailored to specific needs. Fibr’s technology instead aligns website content with campaign messaging, leveraging insights from analytics, advertising data, scroll behaviour, and user attention patterns.
The startup primarily serves enterprise clients in the United States across sectors including financial services, telecommunications, and healthcare. According to the company, businesses using its platform have reported a 35–50% reduction in customer acquisition costs along with as much as a tenfold improvement in engagement and customer satisfaction.
Fibr AI positions its offering as a response to the gap between modern digital marketing strategies and outdated website infrastructure, arguing that adaptive, data-driven experiences are becoming essential for brands seeking stronger online performance.
