Fibr

Fibr AI is an Agentic Web Experience Platform that turns static URLs into intelligent, adaptive landing pages that sense visitor intent and reshape themselves in real time using AI agents with human oversight. Its core product, Fibr Web Pilot, combines no-code A/B testing, conversion-rate optimization (CRO), and personalization — including ad-to-landing-page matching, audience and LLM-visitor personalization, bulk page creation, and AI-driven experimentation — for enterprises, agencies, and growth marketers. The platform integrates with Google Ads, Meta Ads, GA4, CDPs, and major CMS tools, and also ships a large library of free AI marketing tools (headline, hook, CTA, caption, and copy generators, a CRO audit, a landing-page analyzer, and an LLMs.txt generator). Founded in 2022-2023 by Ankur "AJ" Goyal and Pritam Roy and backed by Accel, Fibr is offered through Starter, Agency, and Enterprise pricing tiers. Fibr does not currently publish a public developer API or OpenAPI; this profile captures its identity, developer-adjacent surface, and security/compliance posture.

Fibr is profiled on the APIs.io network. Tagged areas include Company, Conversion Rate Optimization, Personalization, Landing Pages, and A/B Testing.

Fibr’s developer surface includes documentation, pricing, engineering blog, signup flow, support, and 9 more developer resources.
