Autonomous Variant Creation
Go from hypothesis to
live variant in seconds
Fibr’s AI agents create new test versions of your page-copy, images, and layouts included. You can tweak everything instantly in a visual editor, no design or dev help needed.
Adaptive Traffic Routing
Minimize risk while
maximizing learning
Smarter than a 50/50 test. Fibr uses AI to match visitors to the right experience by device, location, and source without losing measurement accuracy.
Scale Powered by AI
Let winning patterns
self-replicate
Fibr automatically scales what’s working and phases out what’s not. Winning experiences expand to similar audiences so revenue keeps growing.
Enterprise-Grade Significance
Trust your results with an adaptive statistical engine
Fibr’s engine automatically selects the most accurate statistical model (Bayesian, Fisher, or Z-test) for your data. You’ll know exactly when an experiment reaches statistical significance (95% confidence).
How it works:
From hypothesis to revenue
No dev bottlenecks. No manual tracking setup.Just a simple sequence
that turns an idea into a winning pattern, step by step.
1
Define Metric
Select a clear primary success metric, like bounce rate, and set a specific target to define what success looks like upfront.
2
Generate Variants
Fibr’s AI agents instantly build multiple variants based on your approved hypotheses. Use the no-code editor for final styling or one-click approval.
3
Set Holdout
Set your traffic allocation. Use a holdout percentage (typically 10%) to ensure a group of visitors still sees the original variant for an accurate performance baseline.
4
Evolve & Scale
Publish the experiment. Fibr tracks performance in real-time, auto-promoting winners so your website evolves autonomously as it learns what works.
