Accel has doubled down on Fibr AI with a $5.7 million seed round, bringing the company’s total funding to $7.5 million after an earlier $1.8 million pre-seed investment in 2024. The round was led by Accel, with participation from WillowTree Ventures, MVP Ventures, and a group of Fortune 100 executives serving as angel investors and advisors. Fibr AI is tackling a growing disconnect in digital marketing: while advertising has become highly personalized, most websites remain static, delivering the same experience to every visitor. The startup uses autonomous AI agents to transform generic webpages into dynamic, one-to-one experiences tailored to individual users in real time. Founded in early 2023 by Ankur Goyal and Pritam Roy, Fibr AI operates as a layer on top of existing websites, integrating with advertising, analytics, and customer data systems to understand visitor intent. Its AI agents then continuously generate and optimize variations of content—copy, images, layout—on the fly, treating each page as a living system rather than a fixed asset. This approach replaces the traditional model of relying on agencies, engineers, and manual A/B testing, which limits enterprises to only a few experiments per year and requires weeks of coordination. Fibr AI runs thousands of micro-experiments in parallel, enabling rapid, data-driven optimization across diverse traffic sources. Goyal emphasized that the platform is designed to be self-sustaining. “We are the software, and the agency is the workforce of agents we are deploying,” he said. Once implemented, the system requires minimal ongoing attention, leading to long-term contracts—typically three to five years—especially among large enterprises like banks and healthcare providers. Early adoption was slow, with only one or two customers in the first two years. But momentum picked up last year, growing to 12 enterprise clients. The fact that regulated, risk-averse industries are investing in the platform has strengthened confidence in its reliability and impact. For Accel partner Prayank Swaroop, the key differentiator isn’t just the AI technology, but the shift in operational model. “Advertising today is one-to-one, but landing pages are still one-to-many,” he said. Fibr AI closes that gap by enabling true personalization at scale, removing the human bottlenecks that have long constrained experimentation. Looking ahead, Fibr AI sees opportunity in the rise of AI-driven discovery. As users increasingly use large language models like ChatGPT to research and shortlist products before visiting websites, the ability of a site to adapt based on what an AI agent already knows becomes critical. While this use case is still emerging, Accel views it as a future-proofing advantage. With the new funding, Fibr AI plans to expand its U.S. sales and customer success teams while continuing to grow its technical base in India, where 17 of its 23 employees are based. The company aims for $5 million in annual recurring revenue by year-end and to reach around 50 enterprise customers. Fibr AI enters a market dominated by incumbents like Adobe and Optimizely, which offer personalization tools but rely on complex setups and ongoing human intervention. Goyal and Swaroop argue these platforms are too slow and rigid to keep pace with modern marketing dynamics. Fibr AI’s agentic, automated approach, they say, is better suited to a world where customer journeys are increasingly driven by AI.
