Fibr Raises $1.8M from Accel and Launches CRO Agents Workforce

Fibr announced a successful $1.8 million seed funding round led by Accel and used it to launch its CRO Agents Workforce, an innovation in Conversion Rate Optimization (CRO) that turns websites into smart, self-optimizing growth machines designed to turn every visitor into a conversion.

What Problem Was Fibr Built to Solve?

Fibr's journey began with the realization that existing CRO tools are outdated and fragmented. Fibr was co-founded in January 2023 by Ankur Goyal, a marketing veteran with over 13 years of experience and education from Stanford and IIT Delhi, and Pritam Roy, an IIT Bombay alumnus with extensive experience building transformative products, out of a need to solve the limitations of traditional CRO platforms. Most CRO solutions are manual and outdated, focusing on a single element like ads or email: they provide generic landing pages, run basic A/B tests, and fail to monitor the website for potential errors that could impact performance. Recognizing this gap, Fibr's founders set out to develop an AI-powered platform that takes the hassle out of optimization, with the goal of creating a solution where websites and campaigns evolve autonomously, delivering conversions through dynamic personalization, continuous optimization, and proactive monitoring. Today, Fibr is empowering marketers with AI-CRO solutions designed to simplify workflows and deliver results without the need for constant manual intervention.

What are agentic web experiences?

Agentic Web Experience is Fibr AI's vision to make every URL an intelligent agent. Instead of showing the same static page to every visitor, agentic websites craft experiences that understand user intent, adapt in real time, learn from performance, and optimize continuously.

How does Fibr AI keep experiences aligned with our brand guidelines?

Fibr AI learns your brand guidelines — voice, messaging, colors, fonts, and visual style — and generates every page, variant, and element within those guardrails. This keeps AI-created experiences consistent and on-brand even as you personalize and test at scale.

Does Fibr AI keep humans in control before experiences go live?

Yes. Fibr AI pairs AI agents with human oversight. Marketers review, edit, and approve AI-generated variants and pages before they publish, so your team always controls what visitors see. This human-in-the-loop approach lets you move fast while protecting quality, accuracy, and brand safety.

How do marketers run A/B tests without a developer or writing code?

Fibr AI is built for marketers to create, launch, and manage A/B tests without code or developer support. You can edit pages visually, generate variants with AI, and publish experiments directly — removing the engineering bottleneck that slows most testing programs.

What does bulk landing page creation look like in Fibr AI?

How does Fibr AI match each landing page to the ad a visitor clicked?

Fibr AI automatically aligns landing page content with the specific ad, keyword, or audience that drove the click. This ad-to-page message match keeps the experience consistent from click to conversion, helping improve Quality Score and conversion rates on paid traffic.

Will Fibr AI personalize experiences for visitors coming from AI assistants like ChatGPT?

Yes. Fibr AI can detect visitors referred from AI platforms like ChatGPT, Gemini, Claude, and Perplexity, and personalize the page to match the intent behind that AI-referred visit — helping you capture and convert this fast-growing source of traffic.

Does Fibr AI localize and personalize pages for different languages and regions?

Yes. Fibr AI can generate localized, vernacular landing page experiences tailored to a visitor's language, region, and market. Global and multi-region teams use this to personalize locally and run region-specific campaigns without rebuilding pages for each market.

Will Fibr AI work on top of our existing website and CMS without replatforming?

Yes. Fibr AI layers onto your current website and CMS, so you don't need to rebuild pages or replatform. It adds personalization and experimentation to your existing setup and works alongside the ad, analytics, and customer-data tools you already run.

What makes Fibr AI different from other website optimization tools?

Fibr AI is AI-native. Where traditional tools rely on manual variant creation, test setup, and personalization rules, Fibr brings audience discovery, hypothesis generation, variant creation, personalization, experimentation, and optimization into one agentic workflow — so teams optimize every experience continuously instead of one test at a time.

Why do enterprise teams choose Fibr AI over conventional CRO or personalization platforms?

Enterprise teams choose Fibr AI when they want personalization and experimentation at scale without the manual overhead or developer dependency of conventional platforms. Fibr AI is AI-native, works on top of existing CMS and martech stacks, and is built for enterprise security and compliance — SOC 2 and ISO 27001 certified, with GDPR and CCPA support.
