As digital advertising becomes increasingly personalized, the websites users land on often remain largely static. Fibr AI is positioning itself to close that gap, using autonomous AI agents to tailor webpages in real time based on visitor intent. The approach has attracted renewed backing from Accel, which led the company’s $5.7 million seed funding round.
The latest investment follows Accel’s earlier $1.8 million pre-seed round in 2024 and brings Fibr AI’s total funding to $7.5 million. WillowTree Ventures and MVP Ventures also participated, alongside several Fortune 100 operators joining as angel investors and advisors.
For large enterprises, the mismatch between personalized ads and generic website experiences has traditionally been addressed through a combination of personalization software, internal engineering teams, and external agencies. That model is often slow, costly, and difficult to scale. While advertisers can quickly generate hundreds of tailored ads, changing a website experience can take weeks and limits how many experiments teams can run in a year.
Autonomous Agents Replace Manual Workflows
Founded in early 2023 by Ankur Goyal and Pritam Roy, Fibr AI replaces that human-heavy workflow with autonomous AI systems. The platform operates as a layer on top of an existing website, connecting to advertising, analytics, and customer data systems. Its AI agents infer visitor intent, generate variations in content and layout, and continuously optimize pages as traffic flows in.
Instead of relying on manually configured rules or sequential A/B testing, Fibr AI runs thousands of micro-experiments in parallel. Each webpage is treated as a dynamic system that learns and adapts, rather than a fixed asset that requires periodic redesigns. According to Goyal, this allows enterprises to evaluate performance based on outcomes such as conversion impact and cost per experiment, rather than staffing levels or agency fees.
Adoption was initially slow, with only a handful of customers during the company’s first two years. Momentum picked up in 2024, particularly among large U.S. enterprises in regulated sectors such as banking and healthcare. Fibr AI now counts 12 enterprise customers and has signed multi-year contracts, reflecting how companies tend to standardize core website infrastructure once deployed.
Competitive and Strategic Context
Accel said the operating model, rather than AI branding alone, drove its decision to invest again. The firm views Fibr AI as addressing a structural limitation in enterprise experimentation, where agency and engineering bottlenecks restrict scale. Early adoption by conservative industries helped validate demand for a more automated approach.
Fibr AI is entering a market long dominated by incumbents such as Adobe and Optimizely, which provide experimentation and personalization tools but often depend on manual configuration and agency-led operations. Fibr AI argues that those constraints make it difficult to move quickly as customer acquisition and messaging become more dynamic.
Looking ahead, the company is also preparing for a shift in how users discover products online. As AI systems increasingly mediate research and comparison before users reach a website, Fibr AI aims to enable sites to adapt based on what a visitor, or an AI agent acting on their behalf, already knows.
With the new funding, Fibr AI plans to expand its U.S.-based sales and customer teams while continuing product development in India. The company is targeting about $5 million in annual recurring revenue by year-end and roughly 50 enterprise customers.
