Imagine websites that adapt to every visitor dynamically, driving revenue autonomously. That’s the future Fibr AI envisions.
Founded by serial entrepreneurs Ankur Goyal (2x) and Pritam Roy (3x) — with backgrounds from IITs and Stanford — we spotted a gap: today’s static websites fail marketers. Fibr AI (fibr.ai) is an enterprise-grade AI Agents platform, building an AI-CRO (Conversion and Revenue Optimization) Agentic Workforce built for consumer marketers that automates optimization workflows in marketing - experimentation, personalisation and performance - to enhance web experiences and drive conversions at scale. This enables companies to run 100x more experiments at 10x the speed of traditional CRO methods, and almost at half the cost of fragmented tools, agencies, or experts. Early results with design partners show promise — think 1,500 tailored landing pages to drive ~20% conversion uplift. Fibr AI integrates seamlessly with existing Martech stacks like CRO tech stack, CDPs, ad platforms, and email systems to ensure that website experiences reflect all the data and insights generated across those channels, making the website an intelligent, responsive part of the marketing ecosystem. Fibr AI eliminates the bottleneck of current CRO - relying on human resources or developers, and replaces traditional CRO agencies (10x market size to CRO SAAS) offering a smarter, faster, and more efficient approach to conversion and revenue optimization. Our Vision? Turn interfaces (websites) into living, self-optimizing revenue driving engines.
