While advertising and targeting have become increasingly personalized, the website — the final destination for that traffic — has remained largely static. Fibr AI aims to bridge that gap by using AI agents to turn generic webpages into one-to-one experiences tailored to each visitor, a thesis that has prompted Accel to double down on the company.
Accel has led Fibr AI’s $5.7 million seed round following an earlier $1.8 million pre-seed investment in 2024. The fresh funding also included participation from WillowTree Ventures and MVP Ventures, alongside Fortune 100 operators joining as angel investors and advisors, bringing the startup’s total funding to $7.5 million.
For large companies, the gap between increasingly personalized ads and largely generic website experiences has traditionally been filled by a mix of personalization software, engineering teams, and marketing agencies — a model that is slow, expensive, and difficult to scale. While ads can be tailored instantly for different audiences, changing what happens once a visitor lands on a site often requires weeks of coordination and limits teams to running only a handful of experiments each year. Fibr AI argues that this human-heavy operating model no longer works. Instead, the startup uses autonomous AI agents to infer intent, generate variations, and continuously optimize pages in real time.
Fibr AI replaces the agency- and engineering-heavy model with autonomous systems that operate continuously, Ankur Goyal (pictured above, right), the co-founder and chief executive, said in an interview.
“We are [the] software, and the agency is the workforce of agents we are deploying,” Goyal told TechCrunch, adding that this allows Fibr AI to run thousands of experiments in parallel rather than a few dozen each year.
Adoption was initially slow. Founded in early 2023 by Goyal and Pritam Roy (pictured above, left), Fibr AI had just one or two customers for much of its first two years as enterprises took time to evaluate the approach. That began to change last year, Goyal said, with adoption picking up among large U.S. companies, including banks and healthcare providers, bringing the total number of customers to 12.
“We are an infra afterthought layer,” Goyal told TechCrunch. “Once it’s set up, nobody wants to think about it again.” That dynamic, he added, has led Fibr AI to sign three- to five-year contracts with large enterprises, which tend to treat website infrastructure as something to standardize rather than continuously revisit.
