Fibr AI Announces $5.7M Seed Boost to Scale Real-Time Website Personalization, +$7.5M Total

Fibr AI, a San Francisco-based platform that deploys autonomous AI agents to transform generic websites into one-to-one experiences, raised $5.7 million in a seed round co-led by Accel. The round brings total funding to $7.5 million, with participation from WillowTree Ventures, MVP Ventures, and Fortune 100 angels and advisors. The startup’s layer-on-top architecture connects to advertising, analytics, and customer data to infer intent and generate, test, and optimize page content in real time, running thousands of micro-experiments in parallel. Adoption accelerated last year among banks and healthcare providers, with 12 enterprise customers and plans to reach 50 by year-end and $5 million in ARR. Fibr AI expands sales and customer teams in the U.S. while maintaining a technical base in Bengaluru, as it positions to outpace incumbent tools by eliminating agency and engineering bottlenecks and delivering outcomes-based cost efficiency.
