Background
Founded in 2023 by Ankur Goyal and Pritam Roy and headquartered in San Francisco, California, United States, Fibr AI (fibr.ai) is an agentic web experience and conversion rate optimization (CRO) platform built for performance marketers, growth teams, and digital agencies across B2B SaaS, e-commerce, financial services, healthcare, and telecom. Operating with a team of 11-50 employees and backed by $9.5M in Seed funding across three rounds from lead investors Accel, MVP Ventures, Sprint Vc, 2am VC, and Kunal Shah, the company solves the post-click conversion drop-off caused by sending diverse paid ad audiences and AI search referrals to static, one-size-fits-all landing pages.
How Fibr AI works
Fibr AI operates at Level 3 autonomy by deploying three specialized AI agents—Liv (Personalization Agent), Max (Optimization Agent), and Aya (Web Performance Agent)—on top of existing websites via a lightweight script tag without requiring engineering rebuilds. Liv connects directly to Google Ads, Meta Ads, LinkedIn Ads, and Google Analytics to read campaign keywords, ad creative messaging, audience segments, and inbound LLM referral context, dynamically rewriting landing page headlines, hero visuals, social proof, and calls-to-action in real time for 1:1 message match. Concurrently, Max analyzes visitor behavior to formulate CRO hypotheses, launches automated A/B and split tests, and shifts traffic toward higher-converting variants, while Aya monitors 24/7 for page latency spikes, broken checkout links, or script errors under SOC 2, ISO 27001, GDPR, and CCPA compliance.
Limitations
Operational limitations and technical trade-offs include:
- Client-Side DOM Manipulation Latency Risk: Dynamically swapping hero headlines and visual elements via client-side scripts requires proper anti-flicker configuration and edge caching to prevent Cumulative Layout Shift (CLS) or brief content flashing on slow mobile connections.
- Statistical Significance Traffic Bottleneck: Running autonomous multi-variant experiments via Max requires sufficient monthly visitor sessions per landing page; low-traffic B2B niche pages face slow convergence timelines.
- Brand & Legal Approval Governance: In regulated industries such as banking, healthcare, and insurance, allowing AI agents to autonomously alter landing page claims or pricing callouts requires human-in-the-loop compliance approval gates.

Fibr AI offers tiered SaaS and enterprise plans (spanning Starter, Agency, and Enterprise editions, with a 30-day pilot option) with custom pricing available on request. Tiers are metered by monthly personalized visitor sessions, number of active domains, and the number of live personalized web experiences and autonomous A/B tests deployed.
