Fibr AI raises $5.7M to automate website personalization

Fibr AI, a startup that uses artificial intelligence to customize web content for individual visitors, has secured $5.7 million in a seed funding round led by Accel. The investment brings the company’s total funding to $7.5 million, following an earlier pre-seed investment of $1.8 million in 2024. Other participants in the seed round include WillowTree Ventures and MVP Ventures.

The funding breakdown includes:

• Seed Round: $5.7 million led by Accel
• Pre-Seed Round: $1.8 million raised in 2024
• Total Funding: $7.5 million

Founded in early 2023 by Ankur Goyal and Pritam Roy, Fibr AI uses autonomous AI agents to turn static websites into personalized web content tailored to individual visitors. The startup aims to replace traditional, human-heavy marketing agencies and engineering workflows with software that continuously runs experiments and updates pages in real time. Goyal, who serves as co-founder and chief executive, described the platform as background infrastructure that operates seamlessly once integrated, meaning clients do not have to continuously manage it. He explained that the startup’s software acts as the core platform while its deployed agents function as the workforce.

The startup currently has 12 customers, having recently seen increased adoption among large U.S. companies in regulated sectors like banking and healthcare. These enterprise clients typically sign three- to five-year contracts. By the end of this year, Fibr AI targets about $5 million in annual recurring revenue and around 50 enterprise customers. This expansion plans to position the startup against incumbents like Adobe and Optimizely, which Goyal and his backers argue have been slow to adapt to automated, real-time experimentation.

Prayank Swaroop, a partner at Accel, noted that the firm invested because Fibr AI addresses a gap in digital marketing. “Advertising today is one-to-one, but when users land on a website it becomes one-to-many,” Swaroop said, pointing out that while ads are highly targeted, the destination websites usually remain generic due to engineering bottlenecks. Fibr AI plans to use the new capital to expand its sales and customer-facing teams in the U.S., while continuing to build out its technical base in India. The startup currently has roughly 23 employees, with 17 based in India and six in the U.S.

Why it matters

Fibr AI is attempting to solve the “one-to-many” website problem by replacing human-heavy agency models with autonomous agents, a shift that has attracted significant backing from Accel. If successful, this approach could redefine how enterprise companies manage digital personalization at scale without relying on slow, manual engineering cycles.
